Guys, hot reload is coming to the server side. 👀
Today, we’re thrilled to share a tech preview of Serverpod 4. 🚀 The first agentic coding engine that hot-reloads the full stack and can run locally on your computer. If you are a developer, this will forever change the way you think about building apps. We are finally closing the loop between your app’s output, the backend, and your AI agent.
Here is what makes Serverpod 4 radically different: Sub-second stateful hot reload across the server, database, web, and app. Everything is wired up to your favorite AI agent through a tried and tested MCP server and skills. We’ve added an embedded Postgres database; there's no need for complex setup or Docker containers. Everything just works.
You can literally see your app evolving as the agent works. No recompilation. No restart. No wait.
Serverpod 4 runs locally on your computer, and with Flutter for the frontend, your app runs at native speed on any platform. And did we say that it’s all free and open source? Join us on Discord to be among the first ones to try it out.
