Undo

Undo.io is an advanced software development platform specializing in agentic and time travel debugging to help developers diagnose and fix complex bugs faster and more accurately. Its patented technology records every step of a program's execution, allowing developers to rewind and replay execution history for precise root-cause analysis, even in large-scale, multithreaded environments. Unlike generic AI coding assistants, Undo is purpose-built for debugging, enabling AI agents to iteratively work on tough bugs until resolved, reducing engineering effort from months to hours. The platform supports languages like C, C++, Rust, Go, Java, and Kotlin and integrates with debugging tools such as GDB and Visual Studio Code. Trusted by leading companies like SAP, AMD, Palo Alto Networks, and Juniper Networks, Undo accelerates release schedules, enhances software stability, and improves customer satisfaction.
