  2. Scale breakpoint
    Free tier limited to 5 reviews; larger teams may need paid plans.
  3. Walled garden
    Moderate: integrates with popular AI coding agents but ecosystem still maturing.

Frequently Asked Questions

Is there a free plan for Ranger?

Yes. Ranger offers a permanently free tier that includes up to 5 feature reviews and self-serve installation, so you can try it without a credit card.

Which AI coding agents does Ranger work with?

Ranger is designed to work alongside popular AI coding agents including Claude, Cursor, and Codex. After the agent writes code, you run `ranger go` to trigger automated browser verification.

How does Ranger differ from a traditional testing framework like Playwright or Cypress?

Ranger sits on top of browser automation (it generates Playwright traces as evidence) but automates the entire QA loop — defining flows, running them, capturing evidence, and feeding failures back to the coding agent for fixing — rather than requiring engineers to write and maintain test scripts manually.

Does Ranger require dedicated QA engineers to operate?

No. Ranger is designed to function as an autonomous QA layer for teams that don't have dedicated testers. Its AI browser agents handle verification and issue reporting, though a human can review and approve results via the dashboard.

Can Ranger tests persist as part of our test suite after a review is approved?

Yes. Once a feature review is approved, Ranger can convert it into a permanent end-to-end test that stays in your suite and continues to run as the product evolves.
