beet

A Very Bevy Metaframework

Guidebook | API Docs

Beet brings bevy to the entire application stack. Going full-stack bevy is a big job and its early days so your mileage may vary depending on your application:

readiness meter

• 🦢 ready to go: documented and tested
• 🐣 near stable: incomplete docs
• 🐉 highly experimental: here be dragons

Beet crates fall into a few main categories.
