Active·★ 29·AGPL-3.0·Updated 2026-10-13

Barbacane is a spec-driven API gateway built in Rust. It uses OpenAPI/AsyncAPI specs as configuration, compiles them into sealed artifacts, and provides routing, validation, authentication, AI traffic management, and MCP support. It features fast performance, security by default, and an extensible plugin system.
