IPWho.org — low-latency IP geolocation API (bare-metal, not hyperscale)
• Free tier: 2,000 requests/day, full functionality, no credit card required
• Core data: country, region, city, timezone, currency, ISP / ASN
• Extras: user-agent parsing + security signals (VPN / proxy / Tor detection)
Architecture & performance
• Built on multi-region bare-metal infrastructure (not typical cloud stack)
• 12+ global origin locations with additional edge acceleration
• <50ms median latency for ~90% of global requests (via regional placement + low-level optimisation)
• Private network design focused on predictable latency and throughput
Pricing & positioning
• Usage-based pricing below typical commercial IP geolocation APIs
• Lower cost base due to avoiding hyperscaler overhead
• Straightforward REST API + SDK support
Intended audience
• Developers who want lower latency + lower cost than standard cloud-hosted IP APIs
• Suitable for real-time use cases where speed and cost per request matter
