results-as-a-service

You don't need a QA team. You need results.

Checksum takes ownership of the testing function, not just the tooling. You get a production-ready Playwright test suite, verified by a seasoned team, and mtaintained continuously so every test is ready to run before it reaches your repo.

the problem

Any tool can generate tests.

The hard part is keeping them working.

Most tools stop where the work starts.

We have heard from engineering teams who generated hundreds of tests with other tools, only to find that every release produced 20, 30, 50 failures with no one to fix them. At that point the tool hasn't saved time. It has created a full-time maintenance job.

Without Checksum

  • Tests break after every release
  • Engineers spend cycles on maintenance, not features
  • No one owns quality when it fails
  • Raw AI output that still needs review

General

Creates production-ready Playwright tests. When your app evolves, the agent automatically heals broken tests.

E2E Agent

Creates production-ready Playwright tests. When your app evolves, the agent automatically heals broken tests.

CI Agent

Creates production-ready Playwright tests. When your app evolves, the agent automatically heals broken tests.

API Agent

Creates production-ready Playwright tests. When your app evolves, the agent automatically heals broken tests.

how it works

Test generated, verified, and maintained for you.

Review. Merge. Move on.

With enough back-and-forth, any tool can generate tests. The real question is what happens when your app changes and those tests break. Checksum detects the break, updates the flow, and submits a fix as a PR automatically.

A testing suite built to last

Every test is built with page object models, reusable functions, and proper architecture. That structure is what allows our agents to maintain tests reliably at scale, and what prevents your suite from becoming unmanageable as your coverage grows.

Verification on every test

AI generates fast. Making sure it's accurate is a different story. Every test Checksum delivers has passed verification before it lands in your repo. You are not reviewing raw AI output. You are approving finished, working tests.

who is it for

Built for teams that want results, not another tool to manage.

No QA team

For teams that need real test coverage but don't have the headcount to build or maintain it. Checksum is your QA function.

Self-Serve Demo

Engineering teams

Your engineers should be shipping features, not debugging selectors. Checksum handles the maintenance so your team stays focused on the code that matters.

QA teams

Stop spending your cycles keeping tests from breaking. With Checksum handling maintenance, your team becomes the strategic layer: exploratory testing, edge cases, and release confidence.

AI skeptics

AI-generated tests that nobody verified are just technical debt in disguise. Every test Checksum delivers has passed verification before it reaches your repo.

getting started

Real tests in your pipeline before you commit to anything.

Get started

Every new customer goes through a structured Proof of Value before signing. The goal is simple: real tests running in your CI/CD pipeline, so you can see exactly what Checksum delivers.

Checksum leads the process. Before the POV kicks off, we handle access, goal-setting, and technical setup. From day one we are building, either from scratch or plugging into your existing page object models and helper functions. Most customers have a fully running test suite in their repo, with daily regression cycles, by the end of the POV.

Throughout, you have a dedicated Checksum solutions engineer on Slack. You stay in the loop on results, review tests as standard PRs, and triage together as success criteria are met.

Every line of code is yours whether you move forward or not.

Frequently Asked Questions

Most tools generate tests and hand them back to you. If they break the next day, that's your problem. Checksum maintains the suite after generation, which is where most teams actually lose time. Every test also goes through senior verification before it reaches your repo, so you're reviewing finished, working tests, not raw AI output.


Every new customer goes through a structured Proof of Value before signing. Most teams have real tests running in their CI/CD pipeline within the first week of kickoff. By the end of the POV, you have a working, maintained test suite in your repo with daily regression cycles already running.


he typical ask is around 1-2 hours per week during the POV: a 30-minute sync and roughly an hour of async review. After that, your ongoing involvement is a regular check-in cadence. Checksum handles the generation, healing, and upkeep in the background.


Yes, completely. Every test is standard Playwright, committed directly to your repository via a standard PR. If you ever move on, your test suite moves with you. No proprietary format, no vendor lock-in.


Checksum detects the break, updates the flow, and submits a fix as a PR automatically. You review and merge. 70% of failures are resolved before anyone on your team needs to touch them.


Checksum connects to your repository and CI pipeline. There is no data migration involved. We generate tests against your live application, either from scratch or by integrating with your existing page object models and helper functions.


No. QA teams use Checksum to get out of maintenance mode and focus on exploratory testing, edge cases, and release strategy. Engineering teams use it to stop debugging selectors. The common thread is that everyone gets time back.


Checksum can integrate with your existing framework and build on what you already have. You do not need to start from scratch.


That is exactly what the Proof of Value is for. You see real tests, in your actual application, running in your CI/CD pipeline, before you sign anything. The decision to move forward should be obvious by the time it wraps.


Stop managing tests. Start shipping features.
