		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 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.

About ATA is an AI-powered API management platform that centralizes design, testing, governance, documentation, and lifecycle workflows into a single intelligent workspace to help teams design, build, test, maintain, and govern APIs with higher quality and collaboration. It keeps API code, design documentation, specifications, test cases, and release notes in sync, reducing manual effort and drift while supporting OpenAPI specs, mock servers for frontend progress without backend readiness, and scheduled API monitoring to detect slow responses, timeouts, or failures early. It includes a Developer Studio for design-first OpenAPI creation and version control, E2E Test Automation with AI-generated robustness and security tests, mock servers, chained API workflows, and UI automation testing, and a Documentation Portal that centralizes API docs with multi-editor support, version management, secure access control, and auto-linked live endpoints.	About The most powerful development environment, now adapted for writing documentation. Use a single authoring environment, eliminating the need for a wide array of tools. With the built-in Git UI, an integrated build tool, automated tests, and a ready-to-use and customizable layout, you can focus on what matters most, your content. You can now combine the advantages of Markdown with those of semantic markup. Stick to one format, or enrich markdown with semantic attributes and elements, Mermaid diagrams, and LaTeX math formulas. Ensure documentation quality and integrity with 100+ on-the-fly inspections in the editor as well as tests in live preview and during build. The preview shows the docs exactly as your readers will see them. Preview a single page in the IDE, or open the entire help website in your browser without running the build. Reuse anything, from smaller content chunks to entire topics or sections of your TOC.
