AI-powered code review that runs code in microVMs to catch more bugs.

Ito, AI Code Review that Runs Code I've been using AI code review tools but none of them actually run code so I built one: https://www.ito.ai/ The way it works is that it uses microVMs to spin up your environment with all of the services running. Then a bunch of AI agents go and test the application to collect runtime evidence. The result is you get test cases along with evidence about whether or not the test cases pass or fail. The runtime evidence can be videos, request/response curls, db

I am developing an alternative work environment to Claude Design. When I first tried Claude Design, I really liked the idea. But after generating a design, I kept wanting a more direct way to continue working on it not as a separate design representation, but as a live, working interface. That’s what I’m building with VisualWizard. The canvas contains real, interactive prototypes. You can select elements directly, move or resize them, change styles, and keep interactions and

I was the only dev at a startup that made it to revenue. Launched my own thing 3 days ago and 61% leave on the first screen The founders I worked with had already built one company that did well before I joined. I was the only developer on the second one, sitting next to them the whole way while it grew into something with real revenue. Watched how they made calls, what they refused to spend time on, how they decided what mattered. Figured I'd absorbed enough to do my own. Three days in, th
