NEW RESEARCH REPORT: Overcoming the limitations of coding agents in complex software systems

Automate root cause analysis with AI – and trust the results

Undo provides the runtime context AI needs to understand complex software behavior, investigate failures autonomously, and verify its findings.

Fix customer issues in hours and avoid escalations.

100x faster root cause analysis on mission-critical code.

AI verifies its findings against recorded program execution.

AI = Model + Context

The bottleneck isn’t the model. It’s the context.

The hardest problems in million-line codebases live in runtime state:

Execution paths

Non-deterministic inputs

Values flowing across module boundaries

Effects far from their cause

Source code can’t show this. Logs don’t capture causality.

So agents fill the gap with plausible guesses, and engineers can’t tell the good answers from the hallucinations.

Code problems agents can solve: 38% without runtime context, 92% with runtime context

The antidote to hallucination

Record, Replay, Resolve

Your agent autonomously records the program execution it needs to investigate a failure or unexpected behavior.

The Undo recording captures the complete program execution: every instruction, every variable, every thread event, every system call.

Unlike logs, recordings capture causality. Unlike traces, they’re complete. And unlike a live debug session, they’re deterministic. The agent can replay the execution exactly as it happened, every time.

From there, the agent queries the recording just as it reasons about static code. But now it can answer the questions source code alone never could:

Why did this variable change here?

What caused this null pointer dereference?

What was the thread state when the crash occurred?

No more guessing. Just the truth about what your program actually did.

Delivered via MCP

Any coding agent can query a recording for exactly the context it needs.

Recordings are self-contained and portable. Capture a problem in development, test, or production, and analyze it anywhere.

Solve problems that were previously out of reach

Use dramatically fewer tokens to reach the same answer

Run cheaper models for work that previously needed the most expensive ones

Why engineering leaders choose Undo

100x faster diagnosis of production problems

Complex root cause solved in hours, not weeks.

Accountability restored

Engineers can review, own and sign off agent output.

Stable, maintainable codebases

Outages and breaches prevented at the source.

AI spend under control

Runtime context lets cheaper models solve more problems using fewer tokens.

Undo AI makes your coding agent smarter, faster and cheaper

The gain comes from the runtime context your agent can read, not from the model it runs on.

Before Undo AI was introduced, I would have taken 1 to 2 days to debug things. With it, we got the exact root cause in 15 minutes.

WILL UNDO WORK ON MY CODEBASE?

What’s the performance impact?

Does Undo work with my coding agent?

Will it work in practice on my large-scale multithreaded applications?

What’s the memory footprint?

We can’t transfer data to you. What data goes to Undo?

How expensive is Undo to run?

Can I use Undo in production?

Will it work on custom devices and custom kernels?

Will it work with distributed code?

Do I need root access?

Okay, so where won’t it work?
