Your Playwright tests shouldn't need a babysitter.

Checksum automatically generates, runs, and heals your Playwright suite. No manual maintenance. No flaky tests slowing down your team. Just code that ships verified.

Helping Companies Ship 10X Faster

The Problem

Playwright is powerful. Keeping it green is painful.

Selectors break. Tests flake. Suites rot. And somebody always has to drop what they're doing to fix them.

Tests break faster thank you write them

Every UI change cascades into broken selectors, failed pipelines, and a suite nobody trusts anymore.

Flaky tests kill momentum

When tests fail randomly, engineers start ignoring them. The suite becomes noise, not signal.

Maintenance is a full-time job

Fixing broken Playwright tests takes time away from building. And with AI agents shipping more code than ever, it only gets worse.

Four core strengths

Everything your Playwright suite needs to stay green

Generate

Stop writing tests from scratch.
Checksum builds a graph of your entire application and generates production-ready Playwright tests automatically. Coverage that would take your team weeks, delivered in days.

Heal

When your app evolves and selectors change, Checksum fixes the broken tests. Your suite stays green without anyone touching it. No maintenance sprints, no test debt.

Run

Checksum runs continuously in your CI, executing your Playwright tests on every commit and deployment. It catches regressions and reports back before you ship.

Own

Tests ship as pure Playwright code directly into your repository. No vendor lock-in. No proprietary format. Your tests, in your stack, forever.
