Checksum

What it does

Checksum is a continuous quality platform that works alongside your CI/CD pipeline. Its agents detect user flows, generate Playwright end-to-end tests and API tests, run them on every commit, and heal broken tests by opening pull requests for review. Tests are delivered as real code in your repository. Setup starts with a demo and a proof of value run with the Checksum team.

The platform has two agents: an end-to-end agent that creates and heals Playwright tests, and an API agent that covers endpoints and payload variations. Tests can be run through the Checksum CLI, in CI, or via a REST API, and reports appear in a web app at app.checksum.ai. When a selector or flow changes, the healing agent fixes the test and opens a pull request. Checksum states that about 70% of failures resolve this way without human involvement. Pricing is based on the number of workflows maintained, with no per-seat fees or per-run charges. Checksum is not self-serve; onboarding begins with a demo and a proof of value.
