ApiNotes
Hi HN I built ApiNotes Mock Server, a small tool that generates a live mock REST API from an OpenAPI (3.0/3.1) or Swagger 2.0 spec. The goal was to remove all friction when you just need a mock API quickly: No sign-up required to create an anonymous mock Supports paste, file upload, or URL fetch Produces a base URL + an auto-generated endpoints list Anonymous mocks currently expire after 72 hours (you can register to keep them / get higher limits) Link: https://apinotes.io/mock-server I’d love feedback on: What would make you trust a mock server like this for real…

OpenAPI mocks that don't suck – realistic test data, quick setup2025 · beeceptor.com · ▲13Hi 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…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
