Beyond configuration drift: how Barbacane reimagines the API gateway with Rust and WASM

What are the key strengths and tradeoffs of using Barbacane for API gateway management?

The key strengths of Barbacane include:

• Spec Integrity: Drift is architecturally impossible due to its compile-first workflow.
• Security Posture: Utilizes Rust + WASM sandboxing, offering better security than Lua/JS runtimes.
• Edge Readiness: Stateless and fast startup with minimal footprint.
• AsyncAPI Support: Rare among gateways; handles WebSockets/MQTT alongside HTTP.
• GitOps Native: Supports a seamless workflow from specs in Git to CI validation and artifact deployment.

The tradeoffs to consider are:

• Young Project: Currently at v0.1.x, actively developed with a growing community but not yet mature.
• Focused Plugin Set: Around 17 official plugins covering core use cases, expanding over time.
• Compile-First Workflow: Changes require CI/CD rather than runtime hot-patching.
• Static Backends: Service discovery needs custom plugin or DNS-based resolution.
