Checksum is a continuous quality platform that generates, runs, and maintains end-to-end and API tests for software teams. It runs alongside CI/CD and produces tests as standard Playwright code committed to the customer's own repository.
The company positions it as a testing partner for coding agents. Tools such as Cursor or Claude Code write tests when asked, while Checksum works continuously in the background, generating, executing, and healing tests without prompting. Its stated goal is to let teams ship faster as code output grows, without trading off quality.
Checksum connects to an existing CI pipeline and works with current frameworks, so there is no rip-and-replace. A team assigns a task, such as generating 20 or 200 tests, and the agent works independently and returns finished results delivered as pull requests.
Once tests are in place, Checksum runs them on every commit, PR, and deployment. It also monitors production errors so that each bug can become a test. When a selector changes or a flow shifts, the platform detects the failure, fixes the test, and opens a PR. The company says about 70% of failures resolve this way without human involvement.
The End-to-End Agent creates production-ready Playwright tests and heals them as the app evolves. The API Agent covers thousands of endpoints, chains calls across multiple systems, and verifies behavior and downstream effects rather than only status codes. API testing is available on Enterprise plans.
Under its Results as a Service model, a human engineer performs final verification so delivered tests are ready to run. Other capabilities include custom style guides and parallel execution on the Scaling plan, a dedicated engineer on every plan, and notifications through Slack, Teams, Discord, Google Chat, email, and webhooks.
Checksum is an AI testing platform that generates, runs, and maintains Playwright end-to-end and API tests automatically. It runs in CI/CD and fixes broken tests as an application changes.
Checksum does not publish dollar prices. It charges by the number of workflows it maintains, with Emerging (50), Scaling (200), and Enterprise (400+) tiers. There are no per-seat or per-run fees.
Yes. Each plan lists a free 30-day trial, and the company also offers a structured Proof of Value using a defined set of tests in your actual application.
Yes. Tests are standard Playwright code delivered to your repository through pull requests. You can run, modify, and keep them if you leave Checksum.
When a selector changes or a flow shifts, Checksum detects the failure, fixes the test, and opens a PR for review. You can approve or reject the change. About 70% of failures resolve this way without human involvement.
It integrates with GitHub, GitLab, Jenkins, CircleCI, Slack, Microsoft Teams, Discord, Google Chat, and custom webhooks. It also supports Anthropic Claude, OpenAI GPT, Google Gemini, Azure OpenAI, and Groq.
No, according to the company. It takes over writing and maintaining tests, so QA staff can spend more time on exploratory testing, edge cases, and quality strategy.
The homepage says most teams run their first tests within a day. The pricing page says most teams have first tests in CI within a week of kickoff.
