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 ZeroStep unlocks the power of GPT-3.5 and GPT-4 to make Playwright tests simpler and more resilient to change. Instead of CSS selectors or XPath locators, ZeroStep's AI assistant determines what actions to take at runtime based on your plain-text instructions. Since ZeroStep integrates directly into Playwright, you can incorporate AI into as few or as many tests as you'd like, without changing your development workflow. Script complex interactions and assertions using plain-text instructions. Use the good parts of Playwright while avoiding common E2E testing pitfalls. No selectors are used, ever. ZeroStep's AI assistant determines what actions to take at runtime. Build tests quickly by expressing actions and assertions as plain text instructions. If you can express what you want tested, you can automate it. Since tests aren't coupled to the implementation details of the application, you can take a TDD approach to write E2E tests.
