Agent Flight Recorder

Cross-provider incident
repair for AI agents.

When a production run fails or burns cost, Lieva records the trace, pinpoints the broken step, replays the fix, and turns the incident into a regression eval.

Forks run locally. Your keys never leave your env.

FAQ

Answers before you commit.

No. Forks and replays run locally in your own environment — your provider keys never leave your machine. Lieva works on the trace you import.

TypeScript SDK first, Python next: OpenAI, Anthropic, the Vercel AI SDK, LangChain / LangGraph, Mastra, and Trigger.dev / Inngest.

Observability shows you the trace. Lieva turns a bad run into a fixed replay and a regression eval — it is the post-incident repair loop, not another dashboard.

Guaranteed early access, a live 1:1 session where we repair one of your real failed runs with you, your $99 credited to month one, 40% off the Founder plan locked for life, and a private founder channel with roadmap influence.
