Checksum vs Test-Lab.ai
Checksum and Test-Lab.ai both use AI to take the manual labor out of end-to-end testing, but they start from different places. Checksum learns from your real user sessions to auto-generate and maintain Playwright tests that land in your repo as pull requests, which is a strong fit for teams with production traffic and a sales-led onboarding. Test-Lab.ai is fully self-serve: you describe a test in plain English, an AI agent runs it like a real user, and you pay as you go.

Should You Switch?
An honest look at when Test-Lab.ai is a better fit, and when Checksum might be the right choice.
Switch to Test-Lab.ai if...
- Start in about two minutes with no demo or sales call: sign up, describe a test in plain English, and watch an AI agent run it.
- Transparent pay-as-you-go pricing with $3 in free credits, instead of a sales-led custom quote.
- You do not need production traffic or an SDK to begin, so brand-new apps and pre-launch flows are testable on day one.
- Describe what to test in plain English rather than reviewing auto-generated tests in pull requests, and still export the underlying Playwright code if you want to own it.
- Built-in scheduled monitoring, pipelines, environments, and agent-native (MCP) access come standard in a self-serve product.
Stay with Checksum if...
- You want tests auto-generated from your real production traffic and analytics rather than describing flows yourself.
- You have meaningful user-session volume and want an AI agent to discover edge cases from how people actually use your app.
- You prefer generated tests to land in your repo as pull requests that your team reviews and merges.
- You want a managed, results-as-a-service model where the vendor maintains a defined set of workflows for you.
