This is a centrally-run implementation of CloudFlare's VibeSDK. It seems pretty solid for prototypes though there are some missing features - I can't figure out how to specify models in the AI Gateway specifically and the build model is fairly weak, it doesn't seem to set up any infra but workers / doesn't have a JSONC editor directly or let you configure infra. A drag-and-drop or scripting engine would be nice.
It does allow temporary git creds so you can clone to a repo and upload to one of your own, so that's nice and helps with the finish engineering portion.
