   Apidog▲570

   Development 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 This fragmented approach leads to outdated API specs and chaotic collaboration.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.

    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…
