Checksum runs continuously in the background, generating, executing, and healing tests automatically without anyone prompting it. The difference is on-demand versus always-on. Most teams find they're spending more time fixing AI-generated tests than writing them. Checksum removes that loop entirely.Does this replace our QA team? No. It removes the low-leverage work, writing and maintaining tests that break every time the UI changes. QA teams that use Checksum spend less time on upkeep and more time on exploratory testing, edge cases, and quality strategy.How long does setup take? Most teams are running their first tests within a day. Checksum connects to your existing CI pipeline and works with your current frameworks. There's no rip-and-replace.Who owns the tests? Do we own the tests? Yes. Tests are delivered as real code: Playwright for end-to-end tests that lives in your repository. You can run them anywhere, modify them however you want, and take them with you. No vendor lock-in.How does auto-healing work? When a selector changes or a flow shifts, Checksum detects the failure, fixes the test, and opens a PR for your review. You see exactly what changed and can approve or reject it. About 70% of failures resolve this way without any human involvement.What if we already have a test suite? Checksum works alongside what you already have, not instead of it. It fills gaps in coverage, keeps existing tests green, and generates new tests as your product changes.Is it accurate enough to trust without reviewing every test? Most teams start by reviewing everything, then gradually extend trust as they see the results. You always have controls: tests come as PRs, healing changes are reviewable, and you can adjust scope at any time.Ready to ship faster?See how Checksum can generate and maintain your entire test suite so you can focus on building.Request a DemoRequest a Demo​​ProductPlatform OverviewIntegrationsSolutions by RoleEngineering TeamsQA TeamsSolutions by AgentAPI AgentE2E AgentCI AgentResourcesResource LibraryBlogTrust CenterDocumentationExplore ChecksumCustomersCase StudiesCompanyVisionCareers© 2026 ChecksumTrust CenterPrivacy PolicyLegal --- Skip to Main ContentGet StartedGet StartedGeneralCreates production-ready Playwright tests.

You give it a task (generate 20 tests, 200 tests) and it works independently. No prompting back and forth. No waiting for each response. The agent goes to work and returns finished results.‍Why it matters: 
‍Coding copilots like Claude Code require constant conversation: prompt, wait, check, run, repeat. With Checksum's high accuracy, you can trust it to work autonomously. This is what enables scale: let it generate hundreds of tests while you do other work.Checksum runs in CI/CD on every commit, every PR, every deployment. It's always on, catching issues while changes are still fresh, not after they've made it to production.‍Why it matters: 
Quality becomes part of your workflow, not a separate gate that slows releases. Feedback arrives when it's most useful, and coverage stays current as your product evolves.Checksum generates coverage at a pace humans can't match—200 tests in 24 hours, not 400 hours of manual work. It handles complex applications with thousands of endpoints and millions of test variations.‍Why it matters: 
‍As AI tools accelerate code output 5-10x, validation can't be a bottleneck. Checksum scales with your engineering velocity. Plus, tests are delivered as Playwright code you own—no vendor lock-in.When your app evolves and tests break (selectors change, flows shift, timing issues), Checksum automatically fixes them. Your test suite stays green without manual maintenance.‍Why it matters: 
‍Traditional test tools break and stay broken until someone debugs them. Engineers spend hours tracking down selector changes and updating code. Checksum reduces time per failure from hours to minutes, with ~70% of failures resolving autonomously. Teams stop stalling on maintenance and keep shipping.​​The AgentsBuilt for autonomous testing at scaleEnd-to-end AgentCoverage that would take months, delivered in weeks.

Selectors change, flows shift, timing breaks. You spend hours debugging failures that have nothing to do with the code you shipped. Meanwhile, PRs pile up and your actual work waits. Test maintenance has become a second job, and it is one nobody signed up for.The frustrating part is that the suite exists for good reason. You need that safety net. But when it cries wolf often enough, engineers stop paying attention. Failures get dismissed. Real regressions slip through because the signal is buried in noise. You end up in a worse position than if the suite did not exist at all: slower to ship, no more confident, and now responsible for keeping a flaky test infrastructure alive on top of everything else.What changes with ChecksumOutcome-focused quality that works in the background, so you don't have to.Self healingTests that fix themselves. When the UI evolves, Checksum automatically heals broken tests and opens a PR for your review.

No rip-and-replace required.How is this different from an AI PR review tool?PR review tools read your code and flag potential issues. Checksum actually runs your code. That's the difference between a suggestion and a verified result.Will this slow down our CI pipeline?No. The CI Agent runs targeted tests on what changed in each PR, not your full suite. It's designed to add signal without adding significant time.What happens when tests break due to UI or flow changes?Checksum automatically heals broken tests and opens a PR for your review. You approve the fix rather than hunting down the selector.Do we own the tests?Yes. Tests are generated as real Playwright code that lives in your repository. No vendor lock-in.How long does it take to get up and running?Checksum connects to your CI and your codebase. Most teams are running tests on PRs within a day, without any manual test setup.Can we start small before rolling it out broadly?Yes. Most teams start with a specific set of critical journeys or a single product area, see it work, and expand from there.Stop spending time on test maintenance.See how Checksum keeps your suite green while you build.Request a DemoRequest a DemoLearn more →​​ProductPlatform OverviewIntegrationsSolutions by RoleEngineering TeamsQA TeamsSolutions by AgentAPI AgentE2E AgentCI AgentResourcesResource LibraryBlogTrust CenterDocumentationExplore ChecksumCustomersCase StudiesCompanyVisionCareers© 2026 ChecksumTrust CenterPrivacy PolicyLegal
