About
Undo is the agentic debugging platform for large-scale codebases, providing coding agents with the runtime context they need to perform fully automated root-cause analysis on complex software. Undo's time travel technology records complete program execution — every instruction, variable, thread event, and system call — creating deterministic recordings that can be replayed and queried via MCP by any AI coding agent. Customers include SAP, Synopsys, Siemens EDA, Cadence, and Altair. The platform is delivered as on-premise software and supports Linux on x86, x86_64, and ARM64.
