An open-source platform that watches your AI agents in production and can automatically catch and fix regressions before users notice them.
Best alternatives to Retrace in 2026
AI agents fail in confusing ways: something goes wrong three tool calls deep, and by the time you notice, you have no clean way to see exactly what the agent was thinking or doing at that moment, let alone confirm your fix actually solves it. Retrace records everything an agent does — every AI call, every tool use, every error — with a single line of code, then lets you rewind to any point in a failed run, fork it, tweak the input, and replay it to see whether the outcome improved, regressed, or stayed the same. Retrace ships Python and TypeScript SDKs with a single decorator for instrumentation, and integrates with LangChain, CrewAI, LlamaIndex, Vercel AI SDK and AutoGen, across OpenAI, Anthropic and Google Gemini models. Beyond replay-and-fork debugging, it adds runtime guardrails (cost budgets, loop detection, latency caps), an auto-classified failure taxonomy, causal graphs for tracing multi-agent sessions, and CI/CD quality gates via GitHub Actions that can block a regression from shipping — effectively turning each production failure into a permanent regression test. Data is encrypted in transit (TLS) and at rest (AES-256-GCM), with automatic PII redaction. Setup is claimed to take about two minutes, and the free tier (1,000 traces/month, 7-day retention) requires no credit card.
