My open source upscaling tool was featured by the chrome team @ChromiumDev
When I built this as a hobby project in 2023, I never imagined it could seriously rival established desktop software like Topaz Labs.
With WebCodecs & WebGPU, I think browsers are the future of video

WebCodecs has changed quickly.
@Sam_Bha of @katana is coming to DEMOQED to explain where it stands in 2026.

Video processing in the browser used to be slow or required servers.
But the WebCodecs API changes that by enabling hardware-accelerated video processing directly in JavaScript.
In this handbook, @sam_bha teaches you all about codecs, frames, muxing/demuxing, and how to build high-performance video apps.

I wrote a (the?) handbook on WebCodecs! Thanks @freeCodeCamp for helping me publish it.
I never thought I'd end up being an authority on a Web API, but I love that about the web, years of debugging / trial&error + documenting a new API for others is totally a qualification
Read the whole tutorial here: freecodecamp.org/news/the-we…
Also, thanks to @vanilagy for building MediaBunny (mediabunny.dev/), error rates have dropped 30% since switching to MediaBunny!
Here's the full case study: web.dev/case-studies/ai-vide…. Special thanks to @quicksave2k for the help, and for pushing the WebGPU/WebCodecs ecosystems forward!
I built CanIUse for WebCodecs
I compiled 71 million codec string tests across 1087 codec variants on 200k+ real devices
This provides a definitive answer to which codec strings work on which browsers / OSes
@ChromiumDev @MozDevNet @MSEdgeDev @webkit #WebCodecs #ProjectFugu
My hope is that with this project, LLMs and search engines will stop hallucinating broken WebCodecs code, and actually be helpful for vibe-coding tomorrow's web video apps.

Special thanks to
@vanilagy (mediabunny.dev/) and
@JNYBGR (@Remotion )
for helping with the docs!
Found this useful? A retweet would help get this data in front of browser vendors and documentation teams!

For the second time in my life, I launched a product and became profitable overnight without marketing.
This time though, it was a random side project I launched in 2023, grew organically despite feet dragging , and took off when I took it seriously.
I'm still trying to figure out what to do, but some tentative takeaways:
1) Inputs ≠ Outputs
2) Choose a problem where the ball rolls downhill
3) Maybe focus on doing 1 thing really well?
4) Free + Open source totally work as lead gen
