plano alternatives
Curated alternatives to plano — and why you'd switch.
litellm
Open-source AI gateway: call 100+ LLM providers in OpenAI format via a Python SDK or self-hosted proxy — with cost tracking, virtual keys, guardrails, load balancing and logging.
Why switchBoth sit between your app and 100+ LLM providers as a self-hosted gateway; LiteLLM is the lighter Python proxy for provider unification and cost control, Plano adds agent orchestration, guardrail filter chains and signals on an Envoy data plane.
Full comparison →agentfield
Open-source control plane that runs AI agents as microservices: write plain Python/Go/TS functions, get REST endpoints with routing, queues, retries, memory and tracing — one laptop to 10k agents.
Why switchSame 'production infrastructure layer for agents' job from opposite ends: agentfield is a control plane that wraps your functions in routing/queues/retries, Plano is a data-plane proxy your unmodified HTTP agents sit behind.
Full comparison →Guardrails
NVIDIA's programmable guardrails for LLM apps: input, output, dialog and retrieval rails defined in Colang, wrapping any model or LangChain runnable.
Why switchTwo places to enforce guardrails: NeMo Guardrails runs Colang rails in-process around a model or chain, Plano enforces moderation/jailbreak filters at the proxy so every agent inherits them without code changes.
