Why this is free & open-source

No paid feed — uses ipapi.co (1k/day) → ipwho.is → ip-api.com (45/min) fallback chain.
Tor detection via public bulk exit list https://check.torproject.org/torbulkexitlist (cached 1h).
VPN/proxy/hosting from free security flags (ipapi.co vpn/proxy/tor, ipwho.is security.*, ip-api.com proxy/hosting).
Client-IP headers (X-Real-IP / XFF / CF-Connecting-IP) are trusted only behind a configured proxy (TRUST_PROXY) — no spoofable echoes.
Self-hostable: no secret, no DB write, 15-min memory cache.

Runs 100% in your browser — no data leaves your device. For programmatic use: curl -X POST /api/v1/tools/ip -d '{ "input": "hello" }' → JSON. See /docs/api.
