Plano is an AI-native proxy and data plane purpose-built for agentic applications, combining request routing, safety guardrails, and deep observability in a single open-source gateway. It sits between application code and LLM providers, giving teams centralized control over how agents communicate with models while keeping vendor coupling to a minimum.
Unified Gateway
- Routes traffic across multiple LLM providers with automatic fallback and resilience controls
- Separates the control plane from model backends for clean architectural boundaries
- Plugin architecture supporting custom middleware for routing, transformation, and policy enforcement
Safety & Policy Enforcement
- Built-in auth, content filtering, and compliance rules applied to every AI request
- Per-tenant rate limits and governance policies for multi-tenant SaaS products
- Ensures every agent request is authenticated, logged, and policy-compliant
Observability
- Native distributed tracing for end-to-end request visibility across providers
- Structured metrics and request-level logging for operational debugging
- Deep observability into agent-to-model communication for production reliability
