		Related Products Checksum.ai 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. 2 Ratings Visit Website MuukTest Are bugs slipping through your QA process and frustrating your customers?

As AI accelerates how software is built, Virtuoso QA helps organisations release with confidence through governed, agentic automation for functional, regression and end-to-end testing across any browser-based application, from Dynamics 365, Salesforce and SAP to Guidewire and custom-built systems. Virtuoso QA turns requirements, designs, live applications or existing suites into executable journeys. Through Touchstone, its agentic layer, brings in 30+ specialised agents to do the work, grounded in your sources and standards. The Analyst turns documentation into source-cited test requirements, the Architect designs the journeys that prove them, and Autopilot builds each one. Your team reviews and approves each stage, so nothing enters the suite on trust. Tests run on a deterministic engine within existing CI/CD pipelines, and self-healing fixes are proposed as reviewable diffs, keeping test suites current without manual rework. Every release is backed by evidence of what was tested, what changed and who approved it. That is why organisations in financial services, insurance, healthcare and the public sector trust Virtuoso QA where releases carry consequences. 131 Ratings Visit Website QA Wolf QA Wolf is the fastest path to deterministic end-to-end test coverage for web and mobile apps.
