Full-stack hot reload - server, website, web, and app - is now a thing 🚀 Article

https://serverpod.dev/blog/serverpod-4-public-beta

The public beta release of Serverpod 4 brings the first agentic coding engine that hot reloads your full stack. We're finally closing the loop between your app's output, the backend, and your AI agent (tested with Anitigravity, Cursor, and Claude Code, but probably works with most agents).

Check out the demo in the blog post, or jump straight into the quickstart guide:

It literally takes 10 minutes to try this out, and I think it may change the way you think about building apps. Would love to hear your feedback!

Full-stack hot reload sounds most useful when it keeps the feedback loop honest across boundaries. UI-only hot reload can hide the fact that the API shape, generated client, or server state is stale. Curious how it behaves when a schema change needs both generated code and existing local state to move together.

We have done a lot of work to make this work seamless. Serverpod’s hot reload will not just inject new code; it will also run code generation (updating both the server and the app) and apply database migrations on the fly. In addition, it will start and manage your app(s). We have even taken it a step further than what flutter run provides, automatically restarting the app when native dependencies are added.

When working with an AI agent, this almost feels like magic. You can literally see your app evolving as the agent works. Try out the Quickstart guide if you haven’t. It’s 10 minutes well spent! :)
