About Cobalt

Cobalt gives an AI developer its own cloud computer. Describe what you want in plain language, and it writes code in your GitHub repo, runs the tests, and shows you the app running live — even after you close the tab. Run multiple tasks in parallel; each gets its own environment. Best for indie developers and small teams who want to parallelize feature work.

Solid core product. The mobile experience for Cobalt needs some work though.

Been recommending Cobalt to my team. Everyone loves it so far.

Cobalt does what it promises. Wish the docs were a bit more detailed.

Bookmarked Cobalt — going to try it this weekend.

The AI features in Cobalt are actually useful, not just gimmicky.
