Overview
Plano is an Envoy-based proxy for agentic apps: a YAML file declares agents (HTTP servers with an OpenAI chat endpoint), model providers and listeners, and Plano routes each turn to the right agent with its 4B orchestrator model (hosted free or run locally). It also routes LLM calls by model name, alias or preference, captures OpenTelemetry traces with no instrumentation and applies guardrails via filter chains.
Who it is for: teams shipping multi-agent apps that need routing and tracing
Strengths
- Declarative multi-agent orchestration; agents are plain OpenAI-compatible HTTP servers
- Zero-code OpenTelemetry traces and agentic signals for every request
- Filter chains add moderation, jailbreak checks and memory out of process
- Model routing by name, alias or preference across providers
Weaknesses
- Agent routing depends on Plano's own orchestrator model; hosted by default
- Install prerequisites live in external docs; README shows only YAML and curl
- Envoy underneath; heavier than a single-binary proxy
- No port or resource guidance beyond example listeners
What it needs
- no GPU
- Docker
- Needs Plano-Orchestrator routing model (hosted or local)
- Models: OpenAI, Anthropic and other providers configured as model_providers
