I was horrified looking at the commit history. The whole project was authored by Claude and it spawned out of a single commit. Really, check it out
Sorry to break it to you, its from our internal project (only the editor part) which had way less feature. And you should watch commit history of open source projects more often every single one usages Claude/codex, people no longer code by hand its over.
I'm pretty sure a good portion of Canva is vibe-coded too. You could argue Canva has tests, QA, etc. But somehow I feel we just tend to associate quality to commercial products.
