phoenix.new is good at getting basic apps working.
It starts with a fully designed mockup and builds all the way to a working real-time app.

You'll get a dev server with a URL you can share—great for showing off in-progress dev work. Phoenix's strengths in clustering, pubsub, and presence pair well with LLM-generated code, making it fun to build simple multiplayer games and collaborative apps.
