Langfuse is an open-source LLM observability tool for engineering teams. Tracira brings AI output monitoring, guardrails, and human approval to non-technical teams running AI in Make, n8n, and Zapier, no code required.
Free plan: 500 monitored outputs per month · No credit card required
Langfuse is a well-regarded open-source LLM observability platform: framework-agnostic, self-hostable, and built for developers who want deep traces and full control over their data.
If you are not a developer and your AI runs inside automations rather than code, that power comes with setup you do not need. Tracira is the no-code alternative: instead of instrumenting an app, you add one webhook step to your automation and write rules in plain English to catch bad outputs.
