Implementation notes
When to use ipstack
ipstack is one of the most recognized IP-geolocation brands, and its 100 requests/month free tier is enough to evaluate data quality before committing. Compared to the no-key options we monitor (ip-api, ipapi.co) its differentiators are the module system (currency, timezone, connection, and security data in one response) and enterprise-grade uptime. Use the free tier for evaluation and low-volume internal tools; for production volume, either upgrade or use IPinfo's much larger free tier.
Common pitfalls
- The free tier is HTTP only — HTTPS requires a paid plan. Browser calls from HTTPS pages will be blocked as mixed content, so free-tier use is effectively server-side only.
- 100 requests/month is tiny — roughly 3 per day. Without caching you'll exhaust it the first morning. Cache by IP with a long TTL or use it purely as an evaluation tier.
- The `security` module (proxy/VPN/Tor detection) shown in the docs is a Professional Plus feature — free-tier responses omit it entirely rather than returning null.
