About Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence.		About Today’s speed of change demands a new way of testing. Empower your teams to build smart tests that don’t break and can scale in the cloud. Rapidly create AI powered tests using the smart agent (Architect) or convert steps written in plain-text English into automation using natural language processing. Stop wasting time fixing broken tests. Functionize dynamically updates your tests using machine learning to keep up with UI changes. Quickly diagnose test failures with one-click SmartFix suggestions. Quickly diagnose failures with screenshot comparisons and and easy to understand errors. Interact with your test while it runs live on the VM using breakpoints with Live Debug. Update your tests using Smart Screenshots and apply one-click SmartFix suggestions. Eliminate test infrastructure. Run as many tests as often as needed across all major browsers at scale using Functionize’s Test Cloud.
