PandaProbe

PandaProbe is an open-source agent engineering platform licensed under Apache 2.0 that provides traces, evaluations, metrics, and live monitoring to debug and improve AI agents. It covers the full agent development lifecycle — from first prototype run to continuous production improvement.

The platform's core strength is its simplicity: a single instrument() call traces an entire agent run automatically, capturing every span including chains, agents, LLM calls, tool invocations, and more. It tracks model types, parameters, token usage, time-to-first-token, and key metadata across runs, giving developers complete visibility into how their agents behave.

PandaProbe integrates with all major agent frameworks including Google ADK, LangChain, CrewAI, AutoGen, and others through its Python SDK. It works with any LLM provider — OpenAI, Anthropic, Google, Mistral, and local models — making it framework-agnostic and provider-agnostic. This flexibility means teams don't need to change their existing stack to get observability.

Key capabilities include distributed tracing for complex multi-agent workflows, evaluation pipelines for measuring agent quality over time, real-time monitoring dashboards for production agents, and detailed cost tracking across different models and providers. The platform helps teams answer critical questions: Why did this agent fail? Which tool calls are slowest? How much is each agent run costing?

Being self-hostable with no vendor lock-in, PandaProbe appeals to teams that need observability without sending sensitive data to third-party services. The Hobby plan is free with no credit card required, with paid tiers available as teams scale. PandaProbe launched on Product Hunt in May 2026 and was recognized as a top product in the DevTools category.
