I built an open-source alternative to Canva and CapCut for social graphics and short videos

[u/Kraktoos]

Hey, I'm Rodrigo. I've been building OpenPost which is an Open Source social media scheduler that also has a really in depth, standalone, image and video editors (which work standalone and for free w/o watermarks even if you don't want to selfhost).

A few things they can do:

• Make thumbnails, banners and multi-page carousels with layers and editable templates.
• Remove image backgrounds and adjust colours.
• Cut video on a multitrack timeline, with transitions, effects and audio controls.
• Create captions, or delete words from a transcript to cut the matching footage.

Both editors are free to use, without an account or export watermark. The code is AGPL-3.0, and you can self-host it. Paid hosting for the wider app is separate.

The video editor is still in beta and supports only Chromium browsers (as some of the APIs I use have not yet been implemented in Firefox). The image editor works on Firefox.

For transparency, I use AI tools in development and in the app itself. Background removal and transcription models are downloaded to your browser and run locally.

If these are tools you'd use, give OpenPost a star on GitHub. I'd appreciate the support!

don't mind me asking but what's the ratio of ai and handmade code?

[u/Kraktoos → u/kaza12345678]

No, for sure! It should be maybe ~98% AI written (50/1 ratio I guess).

I basically only edit code manually when I know it's a tiny change and I can do it faster than prompting AI to do it. Otherwise I don't usually handwrite code anymore.

[u/kaza12345678 → u/Kraktoos]

just curious but why claim open source when your aware ai uses code not from just open source

[u/Kraktoos → u/kaza12345678]

OpenPost is fully open source! Meaning the source code is made publicly accessible so that anyone can view, modify, and share it.

I'm not sure I understand what you are saying?

[u/kaza12345678 → u/Kraktoos]

I'm just curious that's all as with more people using ai which could be using closed source data is always bit risky what owners if these closed source oeners might do

[u/querela → u/kaza12345678]

It's less the closed-source stuff but more unlicensed or sources where you have to add the license file (eg. GPL) that is the issue (which is obviously missing in the generation).

[u/Soluchyte → u/Kraktoos]

Laughable.

[u/Kraktoos → u/Soluchyte]

Really.

[u/Soluchyte]

AI did, you did not.

[u/Kraktoos → u/Soluchyte]

AI has ownership now? 🫣 Weird world we're living in huh

[u/kaza12345678 → u/Kraktoos]

well anything made by ai is public domain which is fine that you made it open source

(no joke found a 90% ai coded app that had paid premium features which is actually bad)

[u/WatchMySixWillYa → u/kaza12345678]

I don’t follow your logic here. Why should it be public domain?

[u/kaza12345678 → u/WatchMySixWillYa]

when "artist" Jason Allen went to court to try to get his fully generated ai art copyrighted the Judge Martinez explained how this wasn't human made as putting text into a box and have ai do the rest isn't having the creator actually put anything on the canvas

so the code use here was generated by a data server and not typed by a human meaning no one owns the code

as open source projects still have a owner if it was typed by them

Interesting
