Ranger Feature Review
Ranger is the always-on AI QA platform for teams that gives you higher signal, less noise, and faster launches.
Ranger Feature Review brings that QA expertise to agentic development. When you ask an AI coding agent to build a feature, Ranger verifies it actually works in a real browser, with real evidence, and gives your team a way to review it collaboratively.
The Problem
Section titled “The Problem”When you ask Claude to build a feature, it might come back to you with a fully working feature, but you can’t tell until you open your app and click through the full workflow involved. And half the time, it writes code that can’t even be built or fails as soon as the page is loaded.
How Ranger Feature Review Fixes This
Section titled “How Ranger Feature Review Fixes This”Ranger acts as your AI agent’s QA team. When your coding agent says it’s done, Ranger runs local browser agents that step through your user flows and verify your features truly look and work the way they’re supposed to.
1. Automated Browser Verification
Section titled “1. Automated Browser Verification”Before your agent says “done,” Ranger tests the feature in a real browser. If something’s broken, Ranger tells the agent to fix it automatically. The agent keeps iterating until Ranger confirms everything works.
2. Feature Review Dashboard
Section titled “2. Feature Review Dashboard”Every verification produces evidence: screenshots, video recordings, and Playwright traces. Ranger presents this in a review interface (think GitHub PR review, but for UI features). You and your team can browse the evidence, leave comments, approve, or request changes.
3. One-Click E2E Tests
Section titled “3. One-Click E2E Tests”Once a feature is verified and approved, you’re one click away from turning it into a permanent end-to-end test in your Ranger test suite.
The Development Cycle
Section titled “The Development Cycle”When you start working on something new, create a feature with the Ranger CLI that describes what should be verified (this is a natural extension of an agent’s Plan mode).
After your agent writes code, it should automatically run ranger verify-feature to walk through the flows, capturing evidence of everything it encounters.
If everything works, great! Your agent can wrap up, let you know it’s done, and you can take a look at the Ranger Feature Review link to get a walkthrough and ask for changes.
If the browser agent finds an issue, it’ll describe it to your coding agent and they’ll iterate until it works or your coding agent decides the work is fully blocked and it needs a human in the loop.
