Checksum

What is Checksum?
Checksum generates, runs, and maintains Playwright end-to-end tests inside your CI pipeline without waiting for someone to prompt it. Three specialized agents handle full user journeys, per-PR change testing, and API endpoint chains. Tests arrive in your repository as standard Playwright code you own, with auto-healing that fixes broken selectors when your UI shifts.
Where coding copilots write tests only when you ask, Checksum runs continuously in the background on every commit and pull request. Its CI Agent generates 50 to 200 targeted tests per PR, and roughly 70% of test failures heal without engineer intervention. That always-on model trades prompt-by-prompt control for coverage that keeps pace with faster AI-generated code output.
Engineering and QA teams use Checksum to cut the productivity drain of flaky test maintenance and manual regression cycles. Pricing is based on maintained workflow count, not seats or test runs. Plans start at 50 workflows on Emerging and scale to 400 plus on Enterprise, with a structured Proof of Value before signing.
