API RadarJan 2026 · apiradar.live · ▲77We 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…
KeyLeak Detector – Scan websites for exposed API keys and secretsNov 2025 · github.com · ▲30I 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…

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…
