What is Spry?

Spry is a lightweight Dart web framework built around a simple idea: the folder tree should describe the server, and the framework should generate the runtime entrypoint needed to run it.

What makes it different

Spry is not trying to be a giant application container. It is trying to be a sharp server layer with:

• file-based routing
• generated app output you can inspect
• explicit middleware and scoped error boundaries
• static asset support
• runtime portability across Dart and selected JavaScript targets

The authoring model

You write a project like this:

routes/
middleware/
public/
hooks.dart
spry.config.dart

Spry scans that structure and builds a concrete app definition from it.

The deployment model

Spry lets you target:

• Dart VM
• Node
• Bun
• Cloudflare Workers
• Vercel
