Manta AI

Manta AI is an autonomous testing agent for web applications. Give it a URL and it explores your app the way a real user would — mapping flows, finding bugs, and generating self-healing test cases. Describe a flow in plain English and Manta tests it for you, no script required. When your UI changes, the tests adapt on their own. Run the agent locally on any machine or server — test apps behind a firewall, on a private network, or even on localhost. Free tier open. No card required.
