Undo Wiki

Undo helps developers understand complex code and fix bugs faster, with time travel debugging for large-scale codebases built on Linux.

Developers spend far too much time figuring out what code actually does – either to understand other people’s code or to find and fix bugs. Debugging can be especially time-consuming when software failures cannot be reproduced.

With time travel debugging, developers can reliably diagnose the root cause of any bug in hours instead of weeks – customer issues, a large backlog of test failures faster, flaky tests, multithreading issues etc. No bug remains unresolved.

Global tech players in networking & security, database, financial services, and EDA use Undo to release on schedule, ensure stability at scale, and boost customer satisfaction.

Record. Replay. Resolve.
