Checksum

Checksum is an automated testing platform that generates, runs, and maintains end-to-end Playwright and API tests.

Checksum is an automated testing platform designed for engineering and QA teams. It generates, executes, and maintains end-to-end Playwright and API tests continuously in the background without requiring manual prompts. When your application evolves or a UI change breaks a test, the intelligent agent detects the failure, heals the test, and opens a pull request for your review. Human engineers also provide final verification to ensure ready-to-go working tests. Tests are delivered as standard Playwright code directly to your repository, preventing vendor lock-in.
