Catching issues early shouldn’t mean overwhelming your team with time-consuming tests. With MuukTest’s AI-driven platform, growing engineering teams reach 95% end-to-end test coverage in just 3 months, delivering quality at speed. By leveraging AI, our QA experts rapidly design, manage, and maintain comprehensive E2E tests for web, mobile, and API applications on the MuukTest platform. Within 8 weeks, we deliver full regression coverage, followed by exploratory and negative testing to uncover hidden bugs and expand test scenarios. We also proactively identify and address flaky tests and false results to ensure the reliability of your tests. Testing early and often allows you to detect bugs in the early stages of your development lifecycle, reducing the burden of technical debt down the line. 34 Ratings Visit Website 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 Virtuoso QA Virtuoso QA is an enterprise agentic test automation platform setting the standard of proof for software releases. 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 KrakenD KrakenD is a high-performance API Gateway optimized for resource efficiency, capable of managing 70,000 requests per second on a single instance.
