Instead of PetalTrace
PetalTrace alternatives
PetalTrace centers on inspecting AI agent execution. It records prompts and completions, tool calls, token use, costs, and timelines, with search, run comparison, and replay for debugging. Developers can use a CLI, HTTP API, MCP server, or web UI, and OpenTelemetry input can bring in traces from instrumented applications beyond PetalFlow. It is free and open source, and its documented local setup uses SQLite.

An alternative may suit you better if your work calls for systematic evaluations, prompt versioning, production alerts, or monitoring application signals beyond agent workflows. PetalTrace's configuration describes authentication as future functionality; its retention defaults and local storage may also matter when planning deployment. Compare the workflows you need to support, the integrations and evaluation tools each product provides, and whether you prefer self-hosting or a paid plan. The alternatives below range from focused agent evaluation to broader observability and team-facing agent workspaces.
