   Mocktail – Free, open-source mock API server with a built-in dashboard▲25

   Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding…

    OpenAPI mocks that don't suck – realistic test data, quick setup▲13

    Hi HN! I'm Ankit, the founder of Beeceptor, a request mocking and intercepting tool. This time, I built something new to address a pain I’ve personally felt (and heard from dozens of QA, frontend, and platform teams): making OpenAPI specs actually useful during development. API contracts just sit around as docs often. What if you could 'activate' them, instantly have a realistic, hosted mock server-with contract validation, smart test data, and early usage? So I made _Mockaroo for OpenAPI_, but with brains. It spins up a hosted mock server from your spec in one click. It: - Generates…

    GraphQL Zero – AIs Mocking APIs▲7

    I made an API mocking tool that imports a schema, populates fake data, then runs a local server. This is helpful for testing APIs or advanced prototyping. A demo video is here: https://www.loom.com/share/abad2cdf325e4e0b9addea1e14406166?... There’s two fun things about this tool 1. the complete lack of configs and schema annotations. i.e. you don’t need to learn faker-js. You just need your existing GraphQL schema and to to swap out the server URL in your frontend code. 2. the depth. Your fake objects have relationships to other fake objects. And in proxy mode, real…

    Hacker News API SDKs → Code Generation in Rust▲39

    Hi Hacker News! Patrick and Elias here. We built an SDK / Documentation generator for REST APIs. The link included shows the shiny output of our system: the docs! We generated 5 SDKs and docs from the Hacker News OpenAPI we found on GitHub. If you write code in Python, Typescript, Go, Ruby, or Rust, we’d love for you to try an SDK out! If you want to generate SDKs for your own API try our tool here: https://github.com/Sideko-Inc/sideko We are both software engineers, and we built this tool because we were spending too much time writing API integrations, supporting…
