Verify work as fast as your agents can write it.

Ranger is the always-on AI QA platform where teams turn big ideas into real products.

Your agent works longer without asking for help.

Ranger gives your coding agent the tools to check itself and keep going, without pulling you in.

One Command

Run ranger go. Ranger spins up a browser, tests your feature, and returns a verdict.

Verify As It’s Built

Ranger spins up a browser, tests your new feature, and returns a demo. Your agent keeps building while Ranger keeps checking.

Auto-Fixes Without You

When Ranger finds a bug, your agent picks it up, fixes it, and re-tests with Ranger. No human in the loop.

Verify your agent’s work. Stop shipping blindly.

Evidence for every change your agent makes. Screenshots, recordings, and traces. Know your entire app is ready to ship, not just your feature.

Request Changes

Leave feedback on any scenario. Your agent picks it up, pushes a fix, and Ranger re-verifies.

Share Proof with Your Team

Every review is a shareable record, screenshots, video, verdicts. Attach to your PR. No meeting required.

E2E Tests with Intelligence

Ranger handles smart test selection before every deploy. Failures are instantly triaged, real bugs get surfaced, the rest is handled.

Your Whole Team Ships Faster.

Coverage that Compounds

Ranger recommends tests for every feature you ship. You approve, they're added to the suite.

Test Suites that Self-Maintain

Tests break as your product changes. Ranger triages what broke and why, Ranger handles the fix. Your suite stays healthy without you touching it.

Auto-Scaling Infrastructure

Spin up hundreds of parallel browsers on demand, scaling with your usage. Available to everyone, not just enterprises.

What our users have to say

“I'm really loving ranger for local QA so far! Had it run through a QA plan for a big feature yesterday and it went smooth with it finding a few bugs and very little effort on my part.”
Matt Hull
Software Engineer - User Evidence

“Ranger has an innovative approach to testing that allows our team to get the benefits of E2E testing with a fraction of the effort they usually require.”
Brandon Goren
Software Engineer - Clay

“Ranger helps our team move faster with the confidence that we aren't breaking things. They help us create and maintain tests that give us a clear signal when there is an issue that needs our attention.”
Matt Hooper
Engineering Manager - Yurts

“We knew we needed to do more testing and internally we would always just make up new excuses for why we couldn't do it. So hiring Ranger to do it for us was pretty much essential.”
Spencer Schoeben
Founding Engineer - Delphi
