Autonomous Test Generation (Playwright)

Checksum’s automated testing feature generates production-ready Playwright test suites for your web application, including structured code like page objects and reusable functions, delivered directly to your repository.

Self-Healing Test Maintenance

As your application changes, Checksum detects and fixes broken tests automatically, proposing updates via pull requests so your suite stays reliable without manual testing upkeep.

PR-Level CI Testing

Checksum lets you generate and run tests for each pull request (often 50–200 tests), helping teams validate specific code changes before they’re merged.

API and End-to-End Coverage

Checksum tests both user-facing workflows and backend systems, covering UI flows and API interactions without requiring separate tools.

Tests as Code (Repository Ownership)

All tests are committed as standard Playwright code directly into your repository, giving your team full ownership and the ability to run them anywhere.

CI/CD Integration

Checksum integrates directly into existing CI/CD pipelines, running tests automatically as part of your development workflow without requiring a separate system.

Fine-Tuned AI-Powered Testing Model

Checksum’s end-to-end testing agent is built on a fine-tuned model trained on over 1.5 million real-world test runs, enabling it to generate higher-quality tests that reflect real user behavior. Combined with custom tools for interaction and assertion evaluation, this allows the platform to produce reliable, production-ready test coverage.

Manual Test Creation (Optional Input & Scenario-Based Generation)

While Checksum automates test generation and maintenance, teams can optionally guide coverage by identifying critical areas or writing test scenarios. The platform then translates these inputs into Playwright tests, combining human insight with automated execution.

Fully Autonomous Testing System 

Checksum operates as a background agent that generates, runs, and maintains tests independently—without requiring ongoing prompts or manual intervention. This enables teams to scale testing output without scaling effort.

Results-as-a-Service Model (Optional Human Verification)

Checksum offers optional human review of test outputs, providing an added layer of validation for teams that want accuracy without sacrificing test automation.

Multi-Agent Architecture

Checksum uses specialized agents for E2E testing, API validation, and CI workflows, enabling deeper coverage across the software development lifecycle.

Checksum isn’t a traditional self-serve testing tool, but it becomes easy to use once implemented. Instead of requiring teams to write and manage tests manually, it handles test generation, execution, and maintenance in the background. While onboarding is guided and involves integrating your environment, repository, and CI/CD pipeline, the day-to-day experience is lightweight—tests are automatically created, updated, and fixed, with changes delivered via pull requests so teams can focus on reviewing results rather than maintaining test suites.

Checksum’s onboarding is structured and fully guided rather than self-serve. New customers go through a Proof of Value (POV), where Checksum works directly with your team to integrate with your environment, repository, and CI/CD pipeline while generating an initial test suite. This approach requires some upfront coordination, but it ensures tests are running in your workflow and delivering value early in the process.

Support is a key part of the experience, with a dedicated solutions engineer available throughout onboarding to help configure coverage, review results, and answer questions. While it’s not an instant setup, most teams begin seeing tests generated and running within the first phase, with a fully functioning test suite typically established over the course of the onboarding period.

Checksum provides a high-touch support model centered around a dedicated solutions engineer, often available via Slack, who assists with onboarding, test coverage setup, and ongoing troubleshooting. Rather than relying on traditional ticket-based support, the experience is more proactive and hands-on, with guidance built into the onboarding process and early usage. This approach is especially helpful for teams adopting continuous testing, as it ensures they get value quickly without needing deep in-house expertise.

Checksum integrates directly with developer workflows and infrastructure, including GitHub and GitLab, CI/CD tools like Jenkins and CircleCI, testing frameworks such as Playwright and Cypress, and multiple LLM providers, including OpenAI, Claude, Gemini, Azure OpenAI, and Groq. It also connects with communication tools like Slack, Microsoft Teams, Discord, and Google Chat to deliver real-time test results and alerts.

In addition to native integrations, Checksum supports webhooks with extensive event coverage and offers an API and SDK for custom workflows and can connect with third-party tools.

Checksum offers strong value for teams looking to eliminate the ongoing cost of writing and maintaining tests, but it’s positioned as a higher-investment solution rather than a low-cost tool. Pricing is based on the number of workflows (tests) maintained—not seats or test runs—which makes costs more predictable as teams scale. While exact pricing isn’t publicly available, the model is designed for organizations that treat testing as infrastructure and want to reduce long-term engineering effort.
