Apidog▲570Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

Hi, this is Mish and Sebastian. We are working on Step CI - a fully automated API testing platform for developers. Step CI works programming-language independent and for different API paradigms (REST, GraphQL, XML). Our CLI and test runner are available on GitHub (https://github.com/stepci) under the MPLv2 license. Since our last launch, Step CI is now able to generate automated tests for your API based on your OpenAPI (Swagger) spec. This saves you a lot of time as you never have to write and maintain your tests again! We would like to invite you to try our tool and give us…

Greetings, What is Jikken? Jikken is an open source CLI tool for automated API testing, built in Rust! The tool was originally developed to help validate complex data APIs used for analytics dashboards while integrating well with source control and CI/CD platforms. When troubleshooting API endpoints, I found my team either messing with gluing cURL/JQ/Diff together, or writing JavaScript in tools like Postman to accomplish essentially the same thing. My goal was a CLI tool which read small test definitions and could execute them seamlessly from both a local machine or in a…

Hey HN, After spending way too many late nights wrestling with brittle test scripts and UIs that seem to change just to spite me, we decided to do something about it. So we built Hercules, an open-source testing agent aiming to make end-to-end testing of modern web applications less of a Herculean task (pun absolutely intended). P.S.- Paid solutions can cost upwords of $15000 and still struggle with maintenance. What is Hercules? Hercules is an AI-powered testing agent that turns simple Gherkin steps into fully automated end-to-end tests, eliminating the need for coding skills. It leverages…

GitHub: https://github.com/ClioAI/kw-sdk Most AI agent frameworks target code. Write code, run tests, fix errors, repeat. That works because code has a natural verification signal. It works or it doesn't. This SDK treats knowledge work like an engineering problem: Task → Brief → Rubric (hidden from executor) → Work → Verify → Fail? → Retry → Pass → Submit The orchestrator coordinates subagents, web search, code execution, and file I/O. then checks its own work against criteria it can't game (the rubric is generated in a separate call and the executor never sees it…
