Checksum

Checksum is an AI-powered end-to-end test automation platform designed to generate, execute, and maintain browser tests with minimal manual effort. Built on top of Playwright, it focuses on making UI and end-to-end testing more reliable and maintainable, especially for fast-changing web applications. Its primary purpose is to help teams keep test suites up to date and robust without constantly rewriting or fixing brittle tests.

Checksum automatically generates Playwright tests from user flows, specifications, or existing application behavior, reducing the need to handcraft every test case. It includes self-healing capabilities that detect changes in the UI and intelligently update selectors and test steps, reducing flaky failures caused by minor front-end modifications. The tool supports full browser coverage, enabling consistent cross-browser validation and regression checks. Integrated dashboards, reporting, and CI/CD hooks allow teams to run tests as part of their deployment pipelines and quickly identify failures with detailed context.
