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 This fragmented approach leads to outdated API specs and chaotic collaboration.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

    Instant API – Build type-safe web APIs with JavaScript▲102

    Hey there HN! I just wrapped up an all-day documentation spree for Instant API, a JavaScript framework for easily building web APIs that implements type safety at the HTTP interface. It uses a function-as-a-service approach combined with a slightly modified JSDoc spec to automatically enforce parameter and schema validation before HTTP requests make it through to your code. You just write comments above your endpoint functions and voila, enforced type safety contracts between your API endpoints and your developers. OpenAPI specifications are generated automatically as a byproduct of simply…

    KeyLeak Detector – Scan websites for exposed API keys and secrets▲30

    I built this after seeing multiple teams accidentally ship API keys in their frontend code. The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a tag visible to anyone who opens DevTools. I've personally witnessed this happen to at least 3-4 production apps in the past year alone. KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS/Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT…

    API Radar▲77

    We built API Radar to track exposed API keys from OpenAI, Claude, Gemini, and other major providers—in real time—from public GitHub repositories. Why? Leaked AI keys are everywhere. They power bots, cost companies thousands, and even expose user data. But no one had a clean dashboard to see the leaks as they happen — until now. What you’ll find: Full redacted + raw API key leaks Real-time feed of exposed repos Leaderboards by author, repo, and provider Filtering by provider (OpenAI, Claude, Gemini, etc.) Timeline of key exposure trends Built for security researchers, devs, and AI companies…
