AI tools for testing web apps and AI features

Let an AI agent click through your web app, write browser tests, or check the answers your own AI feature gives.

For developers and testers who want an AI agent to click through a web app, or who need to check the answers their own AI feature gives. Start with a browser tool for your agent, then add an eval tool once you ship AI.

How we pick

An editor picks 6 to 12 projects for one job and writes when to choose each one. Every pick had a commit in the last 6 months. It is not archived. Its worth score is 60 or more. An editor breaks a rule only for a reason, and writes that reason in the pick's note. We check every list again each quarter. A pick goes when it breaks a rule or a clearly better project appears.
