Phoenix.new is a remote AI runtime for the Phoenix web framework. You describe the app you want, and it starts from a fully designed mockup and builds all the way to a working real-time application.
Every build comes with a dev server on a URL you can share, which makes it handy for showing in-progress work. The team leans into Phoenix's strengths - clustering, pubsub and presence - which pair well with LLM-generated code for simple multiplayer games and collaborative apps.
The service signs you in with Fly.io and is pitched at quickly getting basic apps working rather than replacing a full engineering setup.
