Roadmap

LongHorn is an early alpha on npm, with 17 modules and 4 native hosts. Everything on this page under Roadmap is planned and does not exist today.

Roadmap: edge and own-server hybrid

Planned, not built. Per-service runtime placement would let one project run its API on Workers, its jobs on Bun and its heavy services on your own server, with typed service-to-service calls.

Today, each application picks one host. Separate applications can already call each other over HTTP, and that service client was checked on all four hosts, but placement is not a framework feature.

Not planned

The framework has no built-in LLM features, by design.
