Powered by AI, perfected by humans. Ranger writes and maintains QA tests that find real bugs so you can keep moving forward.
"To accurately capture our models’ agentic capabilities across a variety of surfaces, we also collaborated with Ranger, a QA testing company that built a web browsing harness that enables models to perform tasks through the browser."
“Ranger built an incredibly useful technology enabling agents to navigate and test complex interfaces in unprecedented ways. Dust has no plan to build a QA pipeline, it's Ranger all the way down.”
“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.”
“We’ve loved our experience with Ranger. They make it easy to keep quality high while maintaining high engineering velocity. We are always adding new features, and Ranger has them covered in the blink of an eye.”
“As an AI leader in finance, we rely on Ranger to keep our core flows rock-solid while we innovate rapidly. Their reliable test maintenance saves each product engineer five hours every week, giving us the freedom to focus on cutting-edge financial AI without worrying about bugs slipping through.”
“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."

Our web agent navigates your site based on your testing plan, generating Playwright as it goes. Humans review everything to make sure your tests work and the code is readable.
*Our web agent outperforms Anthropic Computer Use on WebVoyager.
Our web agent automatically triages test failures. Then, our team of QA Rangers perform a comprehensive review to confirm the bug is real.
Keep your team focused on your roadmap. We maintain your core flows and evolve our tests as you launch new features.
Helps you create your testing plan
Runs tests as your code changes
Integrated into CI/CD process
Bugs triaged by us, not your users
QA Expert reviews test code
Human-readable code generated
Tests auto-update with your product
Test infrastructure hosted for you
Flexible capacity as you scale
We integrate with Slack to give you real-time signals, keep your team in the loop, and tag stakeholders for visibility and action.
Your test suite runs as your code changes, with test results shared directly in Github.
Ranger runs against staging/preview environments, allowing you to run crucial tests and catch potential bugs.

Both! Ranger is a bit like a cyborg: Our AI agent writes tests, then our team of experts reviews the written code to ensure it passes our quality standards.
Our team checks that your code is:
1) built correctly
2) readable to other humans
3) is going to be reliable for your team
We love where AI is heading, but we’re not ready to trust it to write your tests without human oversight. With our team of QA experts, you can feel confident that Ranger is reliably catching bugs.
Anyone with a web-based product should be thinking about end-to-end testing. We work best with teams that are focused on building and shipping fast. If that’s you, send a note to howdy@ranger.net to get started.
Nope! We work with products at every stage, whether you’re new to Playwright or looking to migrate an existing suite of tests.
Our team of QA experts will walk you through the process of putting testing on easy mode. We take care of everything, from creating and maintaining your tests to the infrastructure needed to run them.
We base our annual contracts on two main factors: how wide ranging your test suite is and how often you run your tests. Once we chat about your testing needs, we can customize a quote for you.
