plano
plano is a LLM observability tool - Plano is an AI-native proxy and data plane for agentic apps — with built-in orchestration, safety, observability, and smart LLM routing so you stay focused on your agents core logic.
Overview
The AI-native proxy server and data plane for agentic apps. Plano pulls out the rote plumbing work and decouples you from brittle framework abstractions, centralizing what shouldn’t be bespoke in every codebase - like agent routing and orchestration, rich agentic signals and traces for continuous improvement, guardrail filters for safety and moderation, and smart LLM routing APIs for model agility. Use any language or AI framework, and deliver agents faster to production.
Star ⭐️ the repo if you found Plano useful — new releases and updates land here first.
Building agentic demos is easy. Shipping agentic applications safely, reliably, and repeatably to production is hard. After the thrill of a quick hack, you end up building the “hidden middleware” to reach production: routing logic to reach the right agent, guardrail hooks for safety and moderation, evaluation and observability glue for continuous learning, and model/provider quirks scattered across frameworks and application code.
Plano solves this by moving core delivery concerns into a unified, out-of-process dataplane.
plano is open-source, written primarily in Rust, with 6,577 GitHub stars under the Apache 2.0 license. The latest release is 0.4.23 (2026-06-03).
