Core Idea

Plano is an AI-native proxy server and data plane that centralizes routing, orchestration, guardrails, and observability for agentic applications. It pulls out the “hidden middleware” — agent routing, LLM provider switching, safety guardrails, and observability — into a unified out-of-process dataplane, decoupling these concerns from application code.

Key Features

  • Orchestration: Low-latency routing between agents, LLM providers, and tools
  • Guardrails: Safety and moderation filter hooks
  • Observability: Rich agentic signals and traces for continuous improvement
  • Smart LLM Routing: Model agility without framework lock-in
  • Language Agnostic: Use any language or AI framework
  • Built with Envoy Proxy integration, Rust core for performance

Why This Matters

Plano addresses the gap between agent demos and production deployments. The “hidden middleware” problem — routing, guardrails, observability — is exactly what LLMOps platforms need to solve. At 6.9k stars, it’s gaining traction as an AI-native alternative to traditional API gateways, positioning itself as the data plane layer for agentic AI architecture.
