LocationIQ

Nominatim-compatible geocoding, reverse geocoding, and autocomplete with a real 5,000 requests/day free tier.

LocationIQ provides forward geocoding (address to coordinates), reverse geocoding (coordinates to address), and address autocomplete built on OpenStreetMap data, with a request/response shape compatible with Nominatim (place_id, lat, lon, display_name, plus structured address components). Unlike the OSM public Nominatim instance, LocationIQ explicitly permits autocomplete and production use within its quota, making it a clean drop-in when you outgrow the free OSM endpoints. It also offers maps tiles, routing, and matrix endpoints under the same key. The free Developer tier allows 5,000 requests/day at 2 requests/second.

Free tier

Free 'Developer' tier: 5,000 requests/day at 2 req/s, no card to start (commercial use allowed if you add a LocationIQ link). Paid plans (GeoCoding Lite ~$49/mo, Developer Plus ~$99/mo, Starter ~$200/mo) raise daily caps, QPS, and add SLA.

Rate limits

Free tier: 5,000 requests/day at 2 requests/second (per LocationIQ pricing page).
