Open source · part of the bext ecosystem

The plugin registry for the bext engine.

Discover, install, and publish plugins and starter kits — every one sandboxed, so a plugin can extend your server without ever being able to crash it.

Sandboxed by default

Every plugin runs isolated from the host. No filesystem, no network, no crashing your server — unless you explicitly grant it.

WASM

Compiled, near-native, fully memory-isolated. Best for hot-path middleware and codecs.

QuickJS

A tiny JS interpreter per plugin. Instant cold-start, no filesystem, no network unless granted.

nsjail

Hard OS-level sandbox for plugins that need a real process. Seccomp + namespaces.

Publish to the registry

One manifest, one command. We sign it, sandbox it, and surface it to every bext developer.
