Show HN: API Radar – Real-time GitHub scanner for exposed API keys
Hi HN,
I'm a solo dev and student, and I recently built API Radar — a real-time tool that monitors public GitHub commits for leaked API keys (OpenAI, Google Gemini, Anthropic Claude, and more).
What it does:
Scans public GitHub commits in real time
Detects API keys using pattern matching and validation heuristics
Redacts most of the key, but allows copying for verified leaks (for security teams)
Leaderboards by leaky repositories and exposed providers
Built to promote developer hygiene and security awareness
Stack:
Backend: Node.js (Fastify), MongoDB, Redis, custom TruffleHog-like scanner
Frontend: Next.js 14, TailwindCSS, shadcn/ui
Infra: VPS, NGINX + SSL, background worker farm, rate-limit handling
Current stats (soft launch):
210 active users
208 new users
2.6K total events
53s average engagement time
Built fully solo — from design to deployment, analytics to queue resilience. My goal was to ship something fast, security-aware, and production-grade.
Would love feedback on:
Improving UX for security teams
Ethics around redaction and disclosure
Ideas to scale this into an OSS tool or API service
Thanks for reading!

- thebox 1y agoInteresting! UI is minimal but clean, I liked. I have and use a few APIs but sorry about the noob question… I currently see only 3 types of API on your site… is (or will) there any way to search for my own APIs and check if they are leaked? Nice work again.
- zaim_abbasi 1y agothanks for it. for now it only detects 3 api providers from all of github public repos. Regarding the searching your own github profile - so for now there's is not such feature. i will add such features if this site gets traffic, and used by people - as it's no use to implement such things if nobody uses it.
