KeyPing

1. The Founder's Problem

Developers waste hours debugging API integration failures, not knowing if the issue is their code or an invalid/expired API key. Testing keys manually across 10+ providers is tedious, and there's no unified way to check health, rate limits, or permissions.

2. Why Traditional Solutions Failed

• ✗Manual testing requires reading docs for each provider's auth endpoint
• ✗No visibility into rate limits, scopes, or expiry dates until something breaks
• ✗Existing tools are provider-specific or require expensive subscriptions

3. What We Built

• ✓Multi-provider validation: OpenAI, Gemini, Groq, Anthropic, Stripe, GitHub, Twitter/X, Notion, Supabase, AWS, custom endpoints
• ✓Health score (0-100) calculated from validity, scopes, rate limits, and response latency
• ✓Auto-detect provider from key pattern (no manual selection needed)
• ✓Bulk testing: validate multiple keys at once
• ✓Test history with full audit trail, search, and filtering
• ✓Expiry alerts and team workspaces (Pro plan)
• ✓Dark/light mode with emerald glassmorphism UI

6. Tech Stack & Why

7. What We Cut to Ship Fast

• Real-time key monitoring (polling on-demand is sufficient for MVP)
• Slack/Discord notifications (email alerts cover the core need)
• Custom provider SDK generation (too complex for initial launch)

8. Lessons Learned

• →Provider auth endpoints are inconsistent. Spent 40% of time on edge case handling.
• →Health score algorithm needed multiple iterations to feel accurate.
• →Auto-detection from key patterns saved users time but required extensive regex testing.
