Undo Information

Undo provides the runtime context that makes coding agents work on the most complex codebases. AI performance = model + context. Models are getting better all the time; context is now the bottleneck. On large, mission-critical codebases, agents can only solve around 40% of problems — they guess at runtime behavior because source code alone doesn't tell them what actually happened. Undo closes that gap. Undo produces a deterministic recording of program execution. Complete control-flow and dataflow, within and across every module. Coding agents query the recording to reason about dynamic behaviour the way they already reason about static code. The result: fully automated root-cause analysis, with engineers able to see exactly what agent-generated code did and why. Recordings are the antidote to hallucination. Thousands of developers at the world's most demanding software companies, including Nvidia, AWS, Bloomberg and Palo Alto Networks, rely on Undo to solve problems up to 100x faster, release on time, maintain stability at scale, and deliver better customer experiences. Undo is more than a tool. We partner with enterprise engineering teams through concierge onboarding, expert training, and dedicated support to deliver measurable impact within the first six months of deployment.
