Developers

Guides for app authors building on Nimbus: tutorials that teach the platform and how-to guides for getting specific things done. Start with the developer quickstart if you haven’t run Nimbus yet, then build your first app.

  • Build your first app — a complete tutorial: schema, functions, and live queries.
  • Authenticate users — wire an identity provider into your functions.
  • Node.js runtime"use node" actions, packages, and bundling.
  • Building for AI agents? Sandboxes, services, and sessions have their own Agents section.

Each protocol surface has a front door, and the ported-source surfaces (Convex, Firestore, Cloud Functions) add a migration guide. Every server serves these surfaces by default, and nimbus dev detects which one your app uses and wires the app to it automatically. Not sure which to reach for? Adapters explains what a front door is and compares them side by side.

The full per-surface compatibility matrices live in the Reference section.
