Checksum
Checksum
Checksum runs AI agents that generate, execute, and self-heal Playwright end-to-end, CI, and API tests so teams get full coverage without maintenance.
Key features
- End-to-End Agent: Creates production-ready Playwright tests from your app and automatically heals broken tests as the UI and flows evolve.
- CI Agent: Generates 50-200 tests for each pull request scoped to the exact code that changed, and executes them so the PR is already verified by review time.
- API Agent: Covers thousands of endpoints in days with tests that chain across 40+ steps and verify state changes and downstream effects, not just response codes.
- Autonomous Test Healing: Broken tests are repaired by the agents instead of engineers, cutting reported maintenance time by roughly 90%.
- Production Error Monitoring: Watches live errors and converts each real bug into a regression test so the same failure cannot ship twice.
- You Own Every Test: Output is standard Playwright committed to your repo through a normal pull request, so the suite moves with you if you ever leave.
- Results as a Service: Human engineers give a final verification pass on delivered tests, so you receive working suites rather than raw AI output.
- Workflow-Based Pricing: Billing is tied only to the number of maintained workflows — unlimited test runs, healings, and users at every tier.
Best for
- Bootstrapping a First Test Suite: Teams with little or no automated coverage reach 100-150 working E2E tests within the first week.
- Guarding AI-Generated Code: Engineering orgs shipping large volumes of agent-written code get every PR independently exercised before merge.
- Replacing Manual Release Testing: QA teams retire manual regression passes — one customer reported saving 90 hours of manual testing per month.
- Scaling API Coverage: Backend teams cover thousands of endpoints in days instead of spending months hand-writing integration tests.
- Eliminating Flaky Test Maintenance: Engineers stop spending sprint capacity repairing selectors and broken assertions after UI changes.
- Increasing Deploy Frequency: Teams held back by painful release testing gain enough confidence to deploy far more often.
