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. 5.0 out of 5 stars 2 Ratings Visit Website for Checksum.ai 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. 4.5 out of 5 stars 131 Ratings Visit Website for Virtuoso QA 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 API Tester is a completely free mobile app available on iOS, Android, macOS, and watchOS. It is a functional API testing tool that allows users to complete compound tasks on any device. - Test any API on the go: REST, GraphQL, WebSocket, SOAP, JSON RPC, XML, HTTP, HTTPS. - GET, POST, PUT, PATCH, DELETE, etc. HTTP request methods are supported. - Perform the API calls with any kind of request data encoding and transfer type. - Import collections from Swagger, Postman, and YAML, or import requests using cURL, as well as export created requests via link or cURL. - Use a powerful GraphQL editor with full-scale experience. - WebSocket testing tool is available: handles connection and message exchange via WS or WSS. The API Tester mobile app allows you to get the job away from your workstation. Save time, work from anywhere!	About GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server. GraphQL queries access not just the properties of one resource but also smoothly follow references between them. While typical REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request. Apps using GraphQL can be quick even on slow mobile network connections.

Pros & Cons from Real Users Pros API Tester is free. The best GraphQL editor I ever saw. It gives the option to run literally any type of API. Easy import options. Pleasant user experience overall. Learning how to use the app wouldn't take too long. Application is pretty simple, straightforward and works well. Validating Restful and SOAP APIs, WebSocket applications, as well as GraphQL applications has been a good experience using API Tester. All the underlying challenges that come to mind for testing backend applications are well served. What is more important - it's completely free and all features are available without any fees. This mobile app increased my productivity, and I can test APIs from anywhere on the planet using only a mobile device. Cons Not optimal for fully automated testing, but it would be unfair to demand this from a mobile solution. The only cons is the lack of a desktop version. I think it could replace my other desktop alternatives.
