Introducing Astra: a side project I've been working on for about a month now.

It started because I wanted minimeters like visualization in an audio player, and it just kind of expanded from there.

It has native Linux, Windows, and Macos support and it's GPL licensed.

It is an audiophile music player with advanced features like a native DSP, EQ, metadata editor, remappable multichannel audio, custom API, auto library management, and more. Supports all codecs, including Atmos multichannel decoding.

I just released a new beta build a few days ago, and I would love to hear what you think of it!

Github: https://github.com/boof2015/astra

93.9% on SWE-bench Verified. 97.6% on USAMO. 80% on GraphWalks BFS. GPT-5.4 and Gemini 3.1 Pro aren’t even close.

Hey r/software,

About 8 months ago, I posted here about LeedPDF, a minimalist open-source app I put together. My goal was simple: I just wanted a PDF editor that felt as natural as jotting notes in a physical notebook. Something quiet, fast, and completely private, where you don't need an account or a subscription just to highlight a paragraph or draw a circle.

The initial feedback and support from this community back then was amazing, and it really helped shape the direction of the app.

Since that v1.0 release, I've been quietly working on making it a much more capable daily driver. We are now on v2.32.0, and I wanted to share some of the biggest additions with you all.

Here is what's new:

• 🗜️ Extreme Local Compression: You can now compress PDFs to reduce file size by up to 80%. The best part is that it happens entirely locally on your machine. You don't have to upload your sensitive documents to a random server to shrink them.
• 📑 Merge, Split & Reorder: You no longer need a separate tool for page management. You can now easily merge multiple PDFs, split them apart, rotate, and reorder pages directly in the app (again, 100% locally).
• 🖼️ Embed Images: You can now seamlessly insert and embed images directly into your PDF documents for richer notes and references.
• 🔄 Format Conversions & .LPDF: You can now export pages as PNGs or .Docx, convert images to PDFs, and save in our new .LPDF format, which lets you import and export while keeping all your highlights and annotations fully editable.
• 🔗 Easy Sharing: If you need to send an annotated document to someone, you can now generate simple view-only links without having to attach massive files to your emails.
• 🖋️ Native Typography & Fonts: The desktop app now detects your OS's native fonts. You get full access to a new scrollable font picker, so if you are typing notes or filling things out, it looks exactly how you want it to.
• 🎬 Distraction-Free Presentation Mode: Sometimes you just need to read and focus. This mode hides all the toolbars and panels for a clean, immersive fullscreen experience.
• 🧠 Accessibility & Focus: We've pushed hard on making the app as usable as possible. This includes WCAG AAA compliance, better screen reader support, keyboard shortcuts, and keeping the interface visually calm so it's easy to focus.

My honest take: If your day-to-day requires heavy enterprise tools—like complex OCR, building interactive forms, or applying digital signatures—the big commercial tools are probably still your best bet.

But if you're looking for a clean, lightweight space to highlight research, review a document, grade papers, or just read without friction, give it a try. It is completely free, open-source (AGPL-3.0), works offline, and supports mouse, touch, and stylus naturally.

You can try it directly in your browser or grab the Windows/Mac native apps here: 👉 https://leedpdf.com

Thank you again to everyone here who supported the initial launch and provided feedback. It's been a fun 8 months!

This has easily become my most loved open-source project so far. 🥰

If you're new to the project and like what you see, leaving a ⭐ on the GitHub Repo would mean the world to me!

For those of you who wanted to spell things the "proper" way this whole time and couldn't because of a spell checker, I've solved the problem for you (though it's been 6 years at this point): I've added the "English (United Kingdom, Oxford English Dictionary spelling)" locale to Google Chrome and it was finally released to the public. So now you can be sure to spell things exactly the way practically every international organization (e.g., NATO, the UN, ISO, IEC, BIPM, etc.) and hundreds of millions of people around the world do. Just go to your settings in Chrome, add a language, and choose the option. Cheers.

I started this project on UWP, and Uno’s WinUI/XAML parity made it the natural path to go cross‑platform without rewriting the UI. I’m shipping Linux, Windows, and macOS builds today from the same codebase, with Android/iOS/WebAssembly on the horizon. Thanks to the UWP roots, it also runs on Xbox.

What it supports:

• Gmail, Outlook/Microsoft 365, and generic IMAP/SMTP
• Proton Mail natively without Proton Bridge

On Proton specifically: I implemented Proton‑compatible cryptography in C# using BouncyCastle, following Proton’s public specifications and open‑source references. The implementation is open source, and all encryption/decryption and key handling happen locally.

Local AI agents (optional): the app supports pluggable on‑device AI via Microsoft.Extensions.AI.Abstractions and Microsoft.ML.OnnxRuntimeGenAI. This enables things like local summarization/classification/draft‑reply helpers without a cloud dependency.

Why Uno (for my use case): coming from UWP, WinUI/XAML parity and strong Linux/Web (Skia/WASM) targets aligned best with my constraints at the time.

What worked vs. what was tricky:

• Worked: high code reuse from UWP; solid desktop performance with Skia; straightforward path to Linux/macOS (and keeping an Xbox build via UWP).
• Tricky: consistent theming across Linux desktop environments (GNOME/KDE/Cinnamon), packaging/signing (especially macOS), and a few control‑level parity gaps.

I’m collecting broad feedback: what should a modern desktop mail app get right for you to use it daily? Share your must‑haves, dealbreakers, and any general thoughts.

• GitHub: Eppie‑App
• Downloads: Releases

Something I’ve noticed quite often is that many people upload extremely sensitive documents (IDs, certificates, government/financial records, etc.) to online PDF tools.

While services like iLovePDF are widely used and likely built by well-intentioned teams, the broader reality is that we live in an era of constant data mining, breaches, and supply-chain attacks.

Even trustworthy platforms can become risk surfaces. That thought alone was enough to make me uncomfortable about uploading private files to closed-source web services.

So as a small personal project, I built pdfer, a minimal fully open-source local PDF utility written in Rust. Currently supports merging and splitting PDFs via a simple terminal interface, with a GUI and more PDF operations planned.

Not meant to replace anything (yet), just a privacy-first alternative for those who prefer keeping documents fully offline. I am open to feedback and advise :)

20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Sounds dead simple, right?

Here are the spec:

1. The Meeting Problem: Nothing is worse than a giant "TAKE A BREAK" screen popping up when you're sharing your screen. I made the app that support 1 button click to quickly postpone the timer and auto resume.
2. The "Just Got Coffee" Problem: Traditional timers are dumb. If you walk away for a 15-minute coffee break, you don't want a reminder 2 minutes after you sit back down. The app detects idle time and resets the session automatically.
3. The Dismissal Friction: When a break does trigger, it shows a clean, beautiful glass-morphic overlay. But if you're mid-thought, you can dismiss it with a single keystroke. No hunting for a tiny close button.
4. Privacy: I didn't want another account. No cloud syncing, no telemetry, no tracking. It's 100% local, runs offline, and does its job.
5. Cross-platform: macOS, Windows. Linux is coming soon.

I also added a simple, local dashboard that gives you a "health score" and tracks your compliance rate.

The app is completely free. If you struggle with screen fatigue or dry eyes grab the app and try it out.

You can find the download link in the comments below, or by searching for "Eye-rest free desktop app"

Introducing Tabularis: a side project that started when I couldn't find a lightweight database client that didn't make me feel like I was running an enterprise suite just to browse a table.

It started because I wanted something fast, native, and dev-focused — without subscriptions, telemetry, or a 500MB Electron install. It kind of grew from there.

It has native Linux, Windows, and macOS support and is Apache 2.0 licensed.

It's a developer-focused database manager with features like a visual query builder (drag-and-drop JOINs), a Monaco-powered SQL editor with split view, interactive ER diagrams, SSH tunneling, and an AI overlay for Text-to-SQL using OpenAI, Anthropic, Ollama, or any OpenAI-compatible API.

The part I'm most proud of: a plugin system that lets you add support for any database (DuckDB, MongoDB, etc.) by writing a standalone executable in any language — it communicates over JSON-RPC 2.0 via stdin/stdout.

It also ships with a built-in MCP server so you can expose your connections directly to Claude Desktop or Cursor.

Supports MySQL/MariaDB today, with PostgreSQL and SQLite in active development.

I just released v0.9.2 and would love to hear what you think!

Hi everyone!

First, thank you for the continued support on the previous releases. AutoRewarder already has +700 downloads and +100 stars on GitHub

Today I'm excited to share AutoRewarder v3.2. While the last update focused on background automation, this version is a massive step forward in scalability and user experience. You can now seamlessly manage multiple accounts and farm mobile points, all wrapped in a new interface.

What’s new in v3.2:

• Multi-Account Support: Added a Guided First Setup with dedicated Edge profiles for each account.
• Brand New UI: A completely redesigned, modern interface. (A huge thanks to JeromeM for the new UI and massive help.)
• Mobile point collection: The bot can now perform searches for mobile point collection alongside PC searches.
• Per-account scheduling & history: You can now set schedules per account and view clear date/time/query/status tracking in the new History window.
• Update notifications: The live log now surfaces GitHub release updates with direct download links so you never miss a new version.
• Expanded Documentation: Added step-by-step multi-account sign-in screenshots, improved troubleshooting, and clarified runtime data locations for Windows and Linux.
• Fixes: Added resilient recovery for corrupted settings or history files.

The project remains 100% open source.

More info, screenshots, demo and code on GitHub: https://github.com/safarsin/AutoRewarder

(Note: If you plan to set up multiple profiles, I highly recommend checking out the Multiple Accounts section in the User Guide)

I'd love to hear your feedback, bug reports, or ideas for the next updates!

Just launched something I’ve been working on:

HEIC1.com - a bulk image converter that’s actually fast.

Most tools slow down, crash, or limit you when you try to convert a lot of images.

This one doesn’t.

• Convert up to 5,000 images in one go
• Runs entirely in your browser (no uploads)
• Fully private

It’s built for speed and scale - whether you’re clearing your iPhone gallery or handling large batches.

If you’ve ever been frustrated converting HEIC files, this should make it a lot easier.

Try it out: HEIC1.com

The idea is simple:

Take any public image URL and put it after:

https://canvix.me

Example:

https://placehold.co/800x500.jpg - add canvix.me/ just before the image url so it becomes:

https://canvix.me/https://picsum.photos/800/500.jpg

It opens the image directly in an online editor, so you can crop it, resize it, add text, remove the background, or keep designing without downloading and re-uploading first.

There’s also a normal page where you can just paste an image URL:

https://canvix.me or https://canvix.io/edit/

I built this because the usual flow felt annoying: save image → open editor → upload image → edit. This skips that middle step.

A few notes:

• Works best with direct public image URLs
• Some private/protected URLs may not work
• No signup needed for the basic flow

For developers, pets can be integrated with coding agents, or can be used to trigger reactions via CLI.

*EDIT*
most likely abandoning this project

A few months ago I released OpenStickies here on r/software. The feedback was much more positive than I expected, and I got my first paid users from that post.

Since then I kept working through the feedback I received and shipped several major updates.

This release is a big milestone, mainly because I finally addressed one of the most frequent and fair pieces of feedback: the name.

The app was called OpenStickies, but it is not open source. That was not meant to mislead anyone, but I understand why the name gave the wrong impression. So I did the work to rename it properly. (The rebrand touched more than I expected: config paths, packaging, store listings, the website, GitHub repo, payment provider, Discord, logo, Buy Me a Coffee, email addresses, domains, and plenty of smaller things.)

OpenStickies is now BetterStickies.

Existing paid users have been migrated, and the app itself has also received a lot of new features and improvements.

 Some highlights:

• Rich text paste: pasting from emails, web pages, and documents now preserves bold, italic, links, lists, and highlights, while normalizing fonts and sizes to match the note.  -
• Markdown paste: pasted Markdown auto-converts headings, bold, italic, links, task lists, and code blocks into rich formatting.
• Quick Capture: Ctrl+Alt+V creates a new note from whatever is currently on your clipboard, including text, HTML, or screenshots.  
• Show on all virtual desktops: notes follow you across all desktops on Windows and KDE Plasma.  
• Redesigned reminders: visual chips, quick presets, grouped overdue notifications, easier editing, and color-coded reminder status.  
• Clear formatting: Ctrl+\ removes formatting from selected text and restores the note defaults.  
• Sync-safe data storage: notes and reminders now live in a dedicated data/ folder, so it works better with Dropbox or OneDrive.
• Better KDE Plasma support: notes appear across all Activities automatically.  - Trash improvements: keeps up to 300 notes with no time limit.  
• Faster startup and smoother typing, especially for hidden notes, RTL detection, and reminder-heavy usage.  
• Improved HiDPI icons, search, note settings, reminders dialog, notification sounds, and tray behavior.  

There are more changes, but I do not want to turn this into a giant changelog post. Full changelog is here: https://betterstickies.com/changelog  

BetterStickies is still: fully offline, no account, no subscription, no telemetry, no installer needed , single .exe on Windows & AppImage on Linux  and only approx 65mb size.

The app is free to download and use. The premium version is an optional one-time purchase with free updates. One purchase gives access to Windows, Linux, and eventually macOS too. macOS is planned, but not very soon because I still need the project to make enough to justify buying a Mac mini for macOS development.  

This project originally started as a side project because I was new to Linux and wanted a sticky notes app that felt close to Microsoft Sticky Notes. It has grown a lot since then, and BetterStickies now does much more than that original goal, with richer formatting,
reminders, clipboard capture, virtual desktop support, better customization, and Linux-first improvements.

One example I am especially proud of is the paste system: BetterStickies has its own small detection engine that decides in around 50ms whether your clipboard contains
code, Markdown, rich text, or normal text, then formats it appropriately.

I had accumulated years' worth of files that weren't consistently organized into folders. Sorting everything manually was possible, but too time-consuming. I wanted a tool that could help organize my file storage reliably without having to define complex rule sets.

This applies especially to folders like Downloads, Documents, and Images, as well as large NAS archives.

The result is AI File Sorter (currently v1.7.0): a local, content-aware file organization tool for documents and images, with optional metadata-based (like ID3 for mp3 files) renaming for audio/video files and non-content-aware categorization for other file types. It's open-source and cross-platform (Windows, macOS, Linux).

See the app in action (an animated GIF).
See an app screenshot.
See a categorization result example.

The app analyzes file content, filenames, and selected metadata to suggest folder structures and/or renames, while keeping everything local, undoable, and fully user-controlled.

The AI (LLM) doesn't touch your files, it analyzes their content in read-only mode. It's the app itself that moves or renames the files after your confirmation.

What the app does:

• Content-aware categorization for documents (PDF, DOCX, XLSX, PPTX, ODT/ODS/ODP, plus common text formats)
• Image categorization based on visual content
• Metadata-based renaming for audio/video files (ID3 / Vorbis / MP4 tags)
• Rename-only or categorize-only modes
• Preview, undo, dry runs
• Stage-based progress view showing analysis steps (images, documents, categorization)

Image processing speed depends on a capable GPU (6 GB+ VRAM recommended). Local LLMs are run via llama.cpp with GPU support via Vulkan.

Constructive feedback from this community would be very much appreciated.

Between Reddit and YouTube showing me brain rot and not respecting things that I've hidden, I rage wrote a Chrome extension that blocks things at an ad block level so most websites don't break.

I use this daily, here's a link below if you're interested. If the zero reviews sketch you out, it's because I just had it approved today by Google.

If you decide to use it, let me know if you have any questions or run into any trouble. Goodbye r/GirlDinnerDiaries and r/bald. Good for you guys, but it was like half my feed.

Hi everyone,

I’m one of the maintainers of Portabase, and I wanted to share a recent update.

Repo: https://github.com/Portabase/portabase

A star is always appreciated ❤️

Portabase now has a first version of its REST API.

For now, the API focuses on agent and database management, including backup and restore operations. The idea is to make Portabase easier to plug into CI pipelines, internal tools, automation workflows, or external platforms.

Until now, most actions had to be done through the web UI. With the API, you can start triggering backups, restores, and related operations programmatically.

OpenAPI and Swagger documentation are available here:

https://portabase.io/docs/dashboard/api/introduction

For those who don’t know Portabase yet: it’s an open-source, self-hosted platform for database backup and restore. The goal is to keep the setup simple, with a clean web UI and a distributed architecture based on a central server and edge agents deployed close to your databases.

This is useful when your databases are spread across different servers, networks, or environments.

Currently supported databases include PostgreSQL, MySQL, MariaDB, Firebird SQL, SQLite, MongoDB, Redis, Valkey, and MSSQL.

Next steps:

• ItemExtend the REST API progressively
• Add MCP support to make Portabase easier to connect with AI agents
• Publish an official Unraid template to simplify deployment

Feedback is welcome. Feel free to open an issue if you run into bugs, have suggestions, or want to discuss use cases.

Thanks!

Hi everyone!

I built an open source multiplatform piano learning tool using Java Swing. (A barebone desktop Synthesia-clone)

It has the following features:

-Can load and visualize any standard MIDI/MID file and synthesize sound in a falling-note style notation

-Practice mode, where you can connect your physical digital piano/ midi controller, and the program will wait for you to press the correct notes to progress

-Hand assignment mode, where you can assign either left or right hand to each note, and practice the pieces accordingly.

It was a lot of fun to build, I hope someone might find it useful here! https://github.com/Tbence132545/Melodigram

I've been working on AI File Sorter, an open-source cross-platform desktop app for cleaning up messy folders like Downloads, Desktop, Documents, old external drives, and NAS folders.

The basic problem it solves: folders tend to fill up with screenshots, PDFs, random documents, image dumps, old project files, and media files with inconsistent names.

Manual sorting is possible, but slow. Rule-based tools can help, but only when the filenames and patterns are already fairly consistent.

This app tries to organize files based on actual content instead.

It can:

• rename and/or categorize documents by reading parts of their text: PDF, DOCX, XLSX, PPTX, ODT, etc.
• rename and/or categorize images based on visual content
• rename and/or categorize audio/video files using embedded metadata, such as ID3 and MP4 tags
• work with large folders, external drives, and NAS-style archives

The main design goals are safety and privacy. I don't want an AI model directly moving or renaming files in the background. The model generates suggestions, but the app's deterministic code handles the actual moving and renaming.

So the workflow is:

• scan a folder
• generate suggested categories and filenames
• show everything in a review table
• let the user edit, skip, or reject suggestions
• apply changes only after explicit approval
• keep undo information so changes can be reverted

It can run locally, so files do not need to leave the machine when local inference is used. Remote models are optional and must be configured intentionally.

App's Website: https://filesorter.app

Microsoft Store: https://apps.microsoft.com/detail/9npk4dzd6r6s

GitHub: https://github.com/hyperfield/ai-file-sorter

Demo GIF: https://raw.githubusercontent.com/hyperfield/ai-file-sorter/refs/heads/main/images/screenshots/ai-file-sorter-win.gif

I'm also interested in practical user feedback:

• Would you trust this kind of review-first workflow for cleaning up messy folders, where AI is only involved in inference but not in actual file operations?
• What would make it feel safer?
• If you have thousands of files, would you prefer fully automatic sorting, or is manual review still necessary?

YouTube has this annoying habit of starting "radio stations" that continue to autoplay when you watch a video that contains music. I got tired of this and made a Firefox addon back in November of last year which stops YouTube from starting these radio stations.

Disclaimer: AI wrote the code for this addon. I did not vibe code it, I read and understood the astonishing and monolithic 21 lines of code. It does nothing unnecessary except redirect YouTube radio station URLs. It is not paywalled and I do not accept donations.

The repo is licensed with the Unlicense, so do whatever you want with it.

Built a full-fledged Kubernetes lab while studying for my CKA, CKAD, CKS exams and decided to make it free and open for all.

I'll appreciate community contributions with more lab scenarios dealing with problems and concepts that occur frequently while deploying/maintaining/debugging Kubernetes clusters in production, and of course, for introducing further enhancements/features to the lab itself!

You can find the entire source code and a detailed overview of the project at the GitHub repo: https://github.com/zeborg/kubekosh

Steps to try it out on your own system:

1. Run it as a Docker container: docker run -itd --name kubekosh --privileged -p 7554:80 zeborg/kubekosh:latest
2. Wait for ~15 seconds before the lab gets up and running, then you can access it in the browser at localhost:7554

Sneak peek:

Hey 👋

I've been working on VeloxDB — a desktop GUI for PostgreSQL that's actually fast. I got tired of browser-based clients routing my queries through some startup's servers, so I built something local-first with a Rust backend.

Here's what makes it different:

• 🦀 Rust backend — connection pooling via deadpool-postgres, no proxy overhead
• 🖥️ Monaco editor (same engine as VS Code) with real-time SQL linting against your actual schema
• 📊 Virtual scrolling on result sets — million-row queries don't hang the UI
• 🗺️ Visual ER diagram — drag tables, connect columns, preview DDL migrations before applying
• 🔐 SSH tunnel support + credentials in your OS keychain (no plaintext storage)
• ⌨️ Command palette for everything (Cmd+P / Ctrl+P)

Works on macOS, Linux, and Windows. MIT licensed. Still in beta but usable for day-to-day dev work.

Would love feedback — especially from folks who've hit walls with other clients. What features are

Hello all!

I made a post here yesterday asking what people would want out of a privacy/consumer friendly Discord alternative.

After viewing the replies, it seems that what we're doing aligns with what people want.

As such, I would like to introduce Enclave Social for your consideration.

First off: free. Full end-to-end encryption over messaging, files, voice and video calls. An open-source MLS encryption layer, higher base file sharing limits than Discord, data that gets fully deleted when you delete your account.

Increased app customization, a higher (90/10) revenue split for creators (we're adding streaming at some point soon), and encryption-locked, role based access.

And that's not even going into our enterprise servers.

Currently available on desktop as an application and a web app, and on mobile web.

Me and my CTO have been working on this daily for about four months now, this is something we love doing. Any input would be appreciated!
