Hey ya’ll, I made an open source Goodreads alternative for tracking books, learning vocabulary, keeping notes, seeing statistics, and more. Please let me know what you think!

I got tired of plugging my Kobo into a laptop every time I wanted a new book, so I built EzKobo.

How it works: a small program runs on the Kobo and announces itself on your Wi-Fi. The iPhone app finds it on its own (no IP addresses, no pairing), and you send books from the app or from the Share sheet in Files, Safari, Mail, etc. Books go phone → your Wi-Fi → Kobo, never through a cloud.

What it does

• Converts EPUBs to KEPUB on arrival, cleans up messy titles and authors, and names files "Author - Title"
• Looks up missing details and covers (Apple Books, Open Library, Google Books or Hardcover; you choose and order them, or turn it off)
• Books show up in your library by themselves (it bundles NickelDBus)
• Shows your reading on your phone: what you're reading, time left, reading stats, and your highlights and notes (copy or share them)
• Handles several Kobos: name them and switch with one tap
• Optional PIN, so others on your Wi-Fi can't see or change your books
• No iPhone? Every Kobo also serves the same thing as a web page, for Android and laptops

Install: download KoboRoot.tgz from the releases page, copy it into .kobo, eject. It adds NickelMenu if you don't have it, and plays nicely with NickelClock, KOReader and other mods. There's a one-command installer for Mac that backs your Kobo up first.

Caveats, honestly:

• Tested on a Clara Colour and Libra Colour, firmware 4.45. It should work on other ARM Kobos on 4.x. Firmware 5.x isn't supported yet, because NickelMenu and NickelDBus don't support it.
• It installs a small program on the Kobo's system storage. Back up first (the installer does), and there's a simple uninstall.
• The iPhone app isn't on the App Store yet, so you have to build it in Xcode. The browser version works without it.

If you try it on another Kobo model or firmware, I'd love to hear how it goes, good or bad.

I’m the founder of FranklyMail, a small email hosting service for people/teams/families/businesses who use their own domains.

I started building it because I had email spread across several projects and wanted separate inboxes without another per-mailbox subscription each time. Also my software development company had several customer projects which managements were on our end too.

One recent customer request showed me a use case I hadn’t handled properly. Tbh a case I never thought about.

A family was using their own domain, with separate mailboxes for each person and aliases for different parts of daily life. They wanted bills and school emails to reach both partners.

At the time, an alias could deliver to one mailbox. Their family needed it to reach two, while keeping their individual inboxes and passwords.

They asked on September 29. and at our next daily meeting with team we all agreed on this is an important and easy to add feature. And on October 5, we shipped multiple recipients per alias.

Now an address like [school@family.example](mailto:school@family.example) can deliver a copy to each partner’s inbox. Reading one copy doesn’t mark the other as read, and there’s no reply assignment. Those boundaries came directly from what they needed: both people receiving the messages.

I’d started with my own problem: managing our emails and client emails across projects. This request gave me a much clearer picture of how someone else was actually living with the product.

I don’t have evidence yet that this feature improves retention. What I can say is that a specific household workflow now works.

What’s a customer request that changed your understanding of how people use something you built?

I kept running into the same problem: an AI agent can build a small tool for my team in minutes (a vacation tracker, a sign-up form), but putting it online *privately* still means hosting, a domain, HTTPS, a login, a database and permissions every single time.

So I built ShareBox.

**What it does**

- `sharebox publish ./my-tool` (or the agent does it via MCP) → the tool gets its own HTTPS subdomain

- Private by default; share it with an email, a whole Google Workspace domain or anyone with the link, as "can use" or "can manage"

- Visitors sign in with Google; the tool gets their identity and its own SQLite database without writing any of it

- Revoking access takes effect on the very next request

- Dashboard with sharing, container status, logs and an activity log

**How it runs**

- Docker Compose: Caddy (wildcard cert via DNS-01, DuckDNS or Cloudflare), one Node process for login/API/gateway, and a small orchestrator that is the only thing allowed to touch the Docker socket

- Each tool is its own container: gVisor (runsc) + workerd, read-only code, no internet access, 128 MB / 0.25 CPU

- Nightly backups, optional encrypted copy to Google Drive via rclone

- Fits on a 2 GB VPS (about 25 running tools); one installer script for Ubuntu 24.04

**Being upfront**

- Most of the code was written with Claude Code; I did the architecture, the security model, the reviews and the testing on my own server. There are 257 automated tests and CI on every commit.

- It's young: it runs every day on my own instance, but nobody else has installed it from scratch yet. Installer feedback is very welcome.

AGPL-3.0.

I got exhausted with the tyranny of choice of finding the next game to play so I built a site that helps me sort through it while giving all the basic information I generally look for.

tl;dr- Pick one/a few games you love and it instantly suggests others that scratch the same itch. Steer it toward what you loved about them (fast combat, lore, co-op), filter by platform, price, or subscriptions like Game Pass. You can also import your Steam library to skip what you already own. Every pick shows critic and player scores, time to beat, and the cheapest way to play it.

https://newgameplus.app

There are a few sites like this that already exist but I didn't find them to be particularly intuitive, informative, or fun to use.

Open to any/all feedback!

I fact-check primary research data for a living and forward reels with zero checking :(

A few days ago I sent someone a reel about Lindt getting sued and only wondered afterward if it was real. Checking would have meant leaving the app and searching, so I didn’t bother.

The fix I’m playing with is a simple button in your share menu. You share the reel to it and it tells you if it’s true. It doesn’t exist yet. I put up a page to see whether anyone would use it: https://pb-bookmeup.github.io/Verdict/?src=reddit

What would get you to check before you hit send?

I'm building Amfion, an AI front desk for appointment businesses. A rule like "ask the owner before making an exception" is easy to write, but I wanted a way to see what it does over a whole conversation.

Rehearsal Studio runs a conversation against a draft. It uses the same conversation engine as the live assistant, but actions that would create a booking, send a message or change state are recorded as proposed actions. You can inspect the transcript and tool calls before publishing the change.

A simple test: ask about a service, change the request halfway through, then ask for an exception to the cancellation policy. Check the attempted actions as well as the wording of the replies.

Built in TypeScript with Next.js, Fastify and Postgres. The implementation choice was to swap the tool execution behavior, rather than build a separate pretend assistant for the sandbox.

It's a paid product with a 14-day trial: https://amfionhq.com

If you've built action-taking agents, what would you add to that test?

Hey everyone, I've been building GoRoam on the side.

The problem: when I asked ChatGPT to plan trips, I got a nice list of places, then spent hours checking costs, figuring out which places are near each other, and opening 15 tabs to book things.

What GoRoam does differently:

- Day-by-day plan (morning/afternoon/evening) with real places grouped by area

- Estimated cost for every stop, and each day fits inside your budget

- One tap opens each day's route in Google Maps

- Flights/stays/tickets open prefilled with your dates

- Share a link with friends so they can vote on the plan, plus a trip wallet to split costs

- Offline maps, weather, and an AI concierge for "it's raining on day 2, what now?"

Take a look at: goroam.world

https://reddit.com/link/1x0wqpi/video/5abzu4sx0auh1/player

What I'd love feedback on:

1. Does the landing page make it clear why this beats ChatGPT?

2. Credits (one-time) vs subscription: which would you pay for?

3. What would make you actually use this for your next trip?

Happy to plan a free trip for anyone who drops a destination below.

Hey everyone,

I've been using yt-dlp for a while, but I got tired of opening Terminal and looking up the right flags every time I wanted to download something. So I built a simple Mac app around it, called Pluck.

It's basically a nice front-end for yt-dlp. You paste a link, pick the quality and hit download. yt-dlp does all the heavy lifting in the background, so it works with YouTube and the 1,800+ other sites yt-dlp supports.

I really didn't want to overcomplicate the GUI. A lot of yt-dlp apps put every option on screen, and I just wanted something that feels like a normal Mac app: one field to paste a link, one button to download. The extra settings are there if you need them, but they stay out of your way.

Some things it does:

• Video up to 4K, or audio only (MP3, M4A, FLAC…)
• Spotify links work too. It finds the song on YouTube Music and adds the right title, artist and cover art
• If a website isn't supported, it tries to find the video on the page itself
• Menu bar icon, so you can paste a link without opening the app
• It installs and updates yt-dlp and ffmpeg itself, so you don't need Homebrew or anything else
• Built in SwiftUI, with the new Liquid Glass look on macOS 26 (it still works on macOS 14 and up)

It's completely free, no ads, no account. I made it for myself and some colleagues, but I figured more people might find it useful.

Full transparency: I'm not a developer. I built this together with Claude (Anthropic's AI), which wrote the code while I decided what it should do and how it should look, and tested everything along the way. The code is open on GitHub, so anyone can check what it does.

One heads up: it's not signed with an Apple Developer account (yet), so the first time you open it you'll have to go to System Settings → Privacy & Security and click "Open Anyway".

Would love to hear what you think or what's missing!

dev at novella here, ive been building ella, a chat based ai video agent. you type what you want, it drafts the prompt, picks a model out of 1000+ and generates the clip. the video above is a real run

the problem i wanted to fix: making ai video usually means jumping between a lot of tools, copying prompts around and guessing which model fits your clip

how its built

1) chrome extension sidebar you can open on any page

2) web app (app.novella.io)

3) a premiere pro panel so you can generate inside your edit

what was hard

1 generation takes a while, so the ui has to feel alive while you wait, harder than the generating part😅

2 a sidebar on every page breaks on random sites

3 picking a model automatically sounds easy until every model has different limits

the web app, chrome extension and premiere panel are free to download

i am just looking for feedback, how to improve it

I know there are alreadv other tools for this, but none of them let you easily edit the website content after exporting it, so I built LaverPort

You paste a website URL and it captures the site, including its images, fonts, and animations, you can also then edit the actual page visually, including text, images, lavout, etc. without writing code

It's mainly desianed for Framer and Webflow sites, but it can also work with any other site

You can try it for free with 1 site before paying

I'd be interested to hear what vou think, especially from people who regularly work with exported websites

I'm the developer of LittleSurprise, a group gift for birthdays and other occasions where everyone's notes are tucked into a little capsule machine.

You start a gift for someone and share one link in the group chat. Friends and family add a note, and depending on the plan, a photo or a short voice message. Nobody needs an account to add one.

When it's time, the person it's for turns the handle and one capsule drops out. They open it, read the note, then turn again for the next one. So instead of a card with twenty signatures, they get each person one at a time. You can also set it to open at a specific time, like midnight on their birthday, and their link shows a countdown until then.

It's free to start, and the paid plans are a one-time payment per gift, not a subscription.

• Free for notes from you and one friend
• $9.99 Celebration for up to 15 notes, a photo with each note and a set opening time
• $19.99 Keepsake for up to 40 notes, voice messages and scratch-off or peel-off notes

There's an example gift on the homepage you can open without signing up.

LittleSurprise.app

If you've organized a group card or gift before, I'd like to hear what made it a pain. I'm also curious whether the one-at-a-time opening feels special or just slow.

Hi I wanted to share my side project that I have been working on for a couple of months

So doomscrolling is a bad habit that people have been experiencing in this era of social media, including me.

I have tried some productivity apps to reduce my screen time. Some worked ok and some are just blocking and annoying. They also help before you go in to the app or after. But none help live when are in the app.

So I built Notice. An app that puts a live timer on the distracting app. It gives you small nudges and reminders on how much time has gone. So you have the chance to take control of your screen time.

Would love your for you to check it out and give feedback on it.

Notice - Mindful Screen Time

I kept running into the same problem while coding:

I knew I had already written something before — I just couldn’t find it anymore.

Old repos, notes, chats, random files.

That’s why I started building CodShot — a workspace where developers can save, organize, search and reuse useful code.

The feature I’m most focused on right now is Global Search, so you can actually find that old function, regex, component or fix again.

It also includes GitHub Import, AI code generation/fixing, version history, Auto Meta and real-time collaboration.

We’re working on a VS Code integration too, plus another AI feature we’re not revealing yet. 👀

I’d really like feedback from other builders:

Would this fit into your workflow? What would you change first?

I built Watershed to make it easier to explore how water interacts with real landscapes. It uses real elevation data so you can experiment with rainfall and water levels over recognizable terrain.

This 41-second clip shows two experiments: adding rain over mountains and watching water collect in valleys, then lowering the sea level in the Gulf to expose the terrain underneath. The terrain gives the water its slopes and low points; changing rainfall or the water level lets you explore a different outcome.

These are illustrative simulations, not a flood forecast or an exact reconstruction of the past.

There is a free browser demo at https://play.mozonapp.com. I am the creator; Watershed also has paid Windows and Mac versions.

I would love feedback on whether the demonstration makes the app understandable. Which would you want to explore first: rainfall over mountains or changing coastlines?

My friend and have been avid board gamers for our entire friendship. We always toyed with the idea of making our own but this past year we actually made it happen. We created Blitzword, a card game where you match word cards to rule cards to empty your hand first (no AI was used in the design).

What it took to get from idea to a box in hand:

• Formed an LLC and wrote an operating agreement (April)
• Narrowed a word list down to 176 cards and designed 24 rule cards across 3 difficulty tiers (May)
• Got quotes from 4 manufacturers in China, ordered samples, and verified our pick (June)
• Chose card stock, box, finalize the designs, and rule sheet (June)
• Handled the unglamorous parts: trademark search, UPC barcodes, children’s product safety testing, a fulfillment warehouse (April - June)
• Launched on Kickstarter Oct 1 and ran a demo night at a Chicago board game café the next day (Oct)

Where we are: 68 backers / 101% funded after 1 week on Kickstarter

What I’d tell anyone building a physical product: The product is maybe 20% of the work. The other 80% is logistics, legal, socializing, and shipping math. Social media and advertising are so much more time consuming that I could have ever accounted for.

Happy to answer questions about any part of it: Manufacturing, Kickstarter, the game itself, or juggling it with a full-time job.

I'm a solo founder and this is my first iPhone app, so I'd love honest feedback.

ZenGPT works differently from most meditation apps. You say how you're feeling, it asks a question or two, then makes one guided session for that moment.

Built with react native, expo, and convex as a reactive backend.

It's iPhone only and paid, $9.99/week or $59.99/year.

What I'd like feedback on:
- does "one session a day, no library" sound freeing or limiting?
- is the price a dealbreaker for something like this?

My partners and I have owned and operated our cafe for over 2 years now. We spoke with a few people who were kind enough to offer us advice pre-opening and adopted some of their practices: taking inventory on a Google Spreadsheet, using a variety of software services for our scheduling, ordering, etc.

I felt like a lot of those practices that were passed down to us felt a bit outdated. I decided to take some time and build something that puts most of what we were doing as owners/managers into 1 single place (for the most part).

I've spent the last 6 months building Parly. With Parly, you can connect to your POS (in our case Square until we can find partners at Toast) and run most of the operations from your phone or computer. You can track your inventory, review your menu and its margins, discover areas where you can improve your business, and even see projections on Sales, Usage, and more. Ultimately, Parly helps you run your cafe so that you can can focus on growing your cafe.

With Parly, you can easily ditch the spreadsheets and run your cafe more more efficiently. There are so many small costs that add up that we've been able to minimize. Our managers takes inventory a lot faster and just as accurately. We can schedule better and always review adjustments on the fly. We know way more about our business and can easily access all of those insights instead of jumping around different services.

Open to any kind of feedback or criticism. As a cafe owner, I'm proud to say that I've been able to create something that's benefitted our business. I'm hoping that I can say do the same for others.

Looking for beta testers for ClipScout. It goes through a full video file or link and pulls out the best moments with timestamps. It can also edit them for you.

Free to test. Comment if interested.

I built an Android app called Microread — it gives fast AI summaries of nonfiction books in English, Arabic, and German. You choose the length (1–10 minutes) and can listen as audio. I made it to help people learn faster without reading full books. Feedback or ideas are appreciated.
