Frequently Asked Questions

Architecture and operational details for Canary Lab

Canary Lab complements Docker Compose. It runs your application services directly in development mode (e.g., `npm run dev`), leveraging hot reload for immediate feedback on code fixes without Docker image rebuilds. You can use Compose for infrastructure services like databases, and let Canary Lab manage your app services in dev mode.
