Catch JS/TS regressions right after AI edits

Samurai Agent runs in your IDE, using real JavaScript/TypeScript bug data to flag risky AI code changes and review them before you ship.

AI writes code faster than ever — but we’re left wondering what it broke. Samurai Agent is a guardrail for AI-generated code inside your IDE.

How it works

1

You write code with your AI coding tools (e.g. Cursor or Claude Code)

Samurai Agent automatically detects AI edits.

2

Samurai Agent calculates regression risk and shows a warning in your IDE.

It uses JavaScript/TypeScript-specific bug data, so detection is fast and lightweight.

3

Start a code review with one click.

Samurai Agent reviews the change using JS/TS bug data and runtime signals to catch regression bugs.

Samurai doesn’t replace your AI coding agent — it reviews AI-generated code to catch regressions before you ship.

How we do it differently?

JS/TS-specific bug data

Samurai Agent uses real-world JavaScript and TypeScript regression bug data to evaluate AI code changes. This lets us catch last-mile regressions that language-agnostic AI coding agents often miss.

Runtime analysis when it matters

When static signals aren’t enough, Samurai Agent can safely run instrumented code to inspect actual runtime behavior and variables, helping identify the true root cause.

Privacy first

Your code and conversations are never stored or used for training. Only the minimum context required for analysis is processed.
