Rewind lets you fix it - without re-running. Why  •  Demo  •  Install  •  Quickstart  •  Guides  •  Roadmap Single binary · zero dependencies · MIT licensed --- Rewind is an open-source time-travel debugger for LLM-powered AI agents. Every observability tool - Langfuse, LangSmith, Helicone - shows you what happened. None of them let you change the past and observe a different future . Rewind does. The Problem AI agents are shipping to production - tool-calling chains with 10, 30, 50 LLM steps. When they fail, debugging is brutal: - You can't see what the model saw. What was in the context window at step 41? What got truncated? - You can't reproduce it. Re-run the agent and you get a different result. The LLM is non-deterministic. - You can't isolate the failure. Was it step 5 or step 2? You have to re-run all 50 steps ($$$, minutes) just to test a theory. - You can't prove your fix works. You changed the prompt - did it actually improve things, or just shift the problem? Agent broke at step 30? Fix step 30 - not steps 1 through 29 again. Each re-run costs tokens, time, and a different answer. The Solution Rewind is Chrome DevTools for AI agents - fork at any failure, replay with the fix, prove it works.
