   Intercept.rest – Faster API debugging▲89

   Sharing an internal tool that accelerated my development work 10-fold, especially with API debugging. Thought fellow developers here might find it useful. As a developer, I often have trouble reproducing errors at the client end. https://intercept.rest lets me debug and monitor API requests and responses. It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined. Been a long time lurker here and…

    We built a tool that automatically generates API tests▲108

    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…

    Multiple – Load test any API with JavaScript and NPM packages▲38

    Hey HN, I wanted a better load testing solution – so I built one with my team at Multiple. We just opened early access and would love to get your feedback. We created Multiple to solve three challenges with existing tools: 1. Limited scripting capabilities. XML or GUI-based scripting can only test basic scenarios. Existing code-based tools struggle with auth, generating synthetic data, and testing anything other than HTTP requests. We went with JavaScript for ease of use, versatility, and integration with existing developer workflows. 2. Cannot use existing libraries or code. Instead of…
