Know what every change touches, and catch what it breaks before your users do.

PR Lensby Coldtea

Understand

PR Lens keeps a live map of your system and updates it with every pull request. Reviewers see what a change touches and how data moves through it before they read the diff.

Free for open source. Runs on GitHub, GitLab and Bitbucket.

Test

Because Coldtea knows your system, it knows what each change can break. Agents test the flows a change touches automatically, like a real user, on web and mobile. Results land in the pull request.

Watch

After release, it watches Sentry, Datadog and PostHog for problems in the code each change touched. When something breaks, it reproduces the problem and opens a pull request with the fix.

Loved by developers

Most AI-generated code is slop that goes nowhere. Anyone can write code, but building software that works is still hard and requires much more than the ability to prompt a model. I like what these guys just released. Keep your terminal and your coding agent, and use Coldtea to Show more

Tried Coldtea’s QA agent on one of my own side projects last night. Gave it a user flow, then watched it actually drive the browser and click through the live app instead of just scanning the code. It found an edge case I’d completely overlooked. That’s the part that got me.

Coldtea is the control layer for AI-written software. Coding agents now write code faster than teams can read it, so we help engineering teams understand each change, test it before release and keep an eye on it in production.
