Undo (original) (raw)
Automate finding the root cause of complex bugs with AI
Agentic Debugging for Large-Scale Codebases
Get customer issues fixed fast and avoid escalations
Accelerate release cycles by improving team productivity
Fix software defects before they impact customers
Undo applies AI to solving one of the hardest, most time-consuming and costliest problems in software engineering: debugging complex software failures in production and development/test environments.
Debugging is your productivity killer
- Engineers spend 30–50% of their time debugging hard bugs (memory corruption, multithreading issues, flaky tests, or unexpected results), while only < 25% goes to writing code (where most coding agents today are focused).
- Critical bugs delay releases by weeks, sometimes months.
- Defects slipping into production leads to unwelcome escalations.
The LLM hallucination problem
AI agents cannot reliably debug complex codebases because they lack high-quality context and guardrails.
Undo gives AI coding assistants guardrails — so they stop guessing and start reasoning from real execution data. This solution is powered by our time travel debugging technology.
How it works:
- RECORD: Automatically capture program execution (every instruction, threads, variables, I/O).
- REPLAY: Step backward/forward to inspect code flow and see what actually happened — or let the AI drive the Undo debugger for you (autonomous debugging)
- RESOLVE: Give AI the runtime context it needs to accurately explain what the code did or when a variables last changed
The recording is the key. By feeding AI the recording of the program’s execution, it now has the high-quality context it needs to give you a reliable answer.
AI that speeds up engineering
Accelerate software delivery
Ship features faster by speeding up debugging.
Deliver robust releases
Get tickets resolved and minimize defect slippage.
Keep costs under control
Fewer wasted engineering hours spent reproducing and diagnosing bugs.
Ensure core engineer retention
Keep your top engineers engaged by eliminating the most frustrating part of their job.
Speed up onboarding
New hires can quickly understand what the code is doing without having to wait multiple days for other engineers and mentors to be available to assist.
UNDO AI
AGENTIC DEBUGGING
Typing in the code is only a small part of a developer’s job. Understanding large codebases and debugging them takes up far more time.
That’s where Undo comes in. By giving AI code assistants full visibility into how software actually behaves at runtime, Undo enables them to understand complex systems and fix bugs more accurately and cost-effectively.
Undo makes AI better.
