Undo is the time travel debugging company for Linux

We equip developers with the technology to understand complex code and fix bugs faster. 

Developers spend far too much time figuring out what code actually does – either to find and fix bugs or to understand other people’s code. With time travel debugging, developers can see exactly what the software did, and create better software faster. By integrating Undo’s LiveRecorder into their CI workflow, C, C++, Go, and Java software teams can easily and quickly diagnose the root causes of new regressions, legacy bugs, and flaky tests – before they hit customers. 

Thousands of developers across leading technology firms including SAP, Juniper Networks, and Siemens use LiveRecorder to improve developer productivity, developer velocity, and software quality.

The story of Undo

Undo started out as a fast-growing technology start-up founded by Greg Law and Julian Smith. Both started working evenings and weekends in Greg's garden shed, determined to build a tool for developers to ease the pain of debugging complex software.

Following receipt of seed funding in 2012, the company is now established as the time travel debugging company for Linux software development.
