Unlike generic AI tools that produce fragile code or black-box results, Endtest creates standard steps that users can review, modify, reuse, and execute like any other test. Endtest supports web, mobile, API, database, email, SMS, file, visual, accessibility, cross-browser, geolocation, and CI/CD testing. It is useful for QA teams, developers, product managers, founders, and organizations that want reliable automation without a custom framework. The platform includes AI-powered test maintenance, migration from other tools, file imports, and self-healing capabilities that reduce broken tests when apps change. Tests run in the cloud across browsers, operating systems, resolutions, and geolocations, helping teams validate user journeys. With unlimited AI usage and unlimited test executions, Endtest gives teams a predictable way to adopt AI-powered testing at scale without tokens, credits, or usage limits.
