Checksum

What is Checksum?

Checksum is a continuous quality platform that builds and maintains automated tests for software teams. Its end-to-end agent writes Playwright tests for your user flows, an API agent chains calls across endpoints and checks the system's behavior beyond status codes, and a CI agent runs in your pipeline on every commit. If a selector changes or a user flow shifts, Checksum notices the failure, repairs the test and opens a pull request for review, and the vendor says about 70 percent of failures resolve this way without a person. The service is sold as Results as a Service, so a human engineer verifies the suite and a dedicated customer engineer is available on Slack. Tests are standard Playwright code in your own repository, so there is no lock-in. Pricing is tied to the number of workflows Checksum maintains, with no per-seat or per-run fees, across Emerging, Scaling and Enterprise tiers. Dollar prices are not published, and a Proof of Value is offered.

Use cases

• Generate Playwright end-to-end tests
• Auto-heal broken tests after UI changes
• Test APIs across chained calls
• Replace manual release regression testing
• Migrate an existing test suite
• Turn production errors into regression tests

Who it's for

• Engineering teams
• QA teams
• Startups
• Engineering leaders

Why use Checksum

• Pricing by maintained workflow means your bill does not grow when you hire engineers or run CI more often.
• You own plain Playwright tests, so you keep them if you ever leave.
• Auto-healing and human verification reduce the maintenance load that usually sinks AI-generated suites.
• Always-on agents work in the background, unlike coding assistants that need constant prompting.
• A Proof of Value shows results on your own application before you sign anything.

How to get started with Checksum

1. Checksum scopes your key user flows and connects to your CI pipeline.
2. The agents generate Playwright tests, and an engineer verifies them before delivery.
3. Tests arrive in your repository as standard pull requests that you review and merge.
4. They run on every commit; when the app changes, Checksum heals failing tests and opens a new PR.
5. Add workflows or move up a tier as your coverage needs grow.

Checksum limitations

• Dollar prices are not published; pricing is by number of maintained workflows
• One workflow is an end-to-end test of up to 30 actions
• API testing agent is available on Enterprise plans only
• No self-serve trial; a structured Proof of Value is offered instead
