What Tile38 is

Tile38 is a geospatial database and geofencing server for location-based applications. It indexes spatial data and supports searches for objects that intersect, sit within, or are near a defined area, as well as static and roaming geofencing. It can send real-time geofence notifications for datasets ranging from a few points to millions. Supported data includes latitude and longitude points, bounding boxes, XYZ tiles, geohashes, and GeoJSON, along with other listed spatial types such as QuadKey and sectors. Tile38 supports 3D geometry but does not provide coordinate transforms. It is open source under the MIT license and is self-hosted, with Docker, package, and binary installation options. Applications can connect through HTTP, WebSockets, or telnet, with JSON or RESP responses; its native Redis protocol also works with many clients that support basic Redis commands. It lists integrations for messaging and streaming systems, including NATS, Kafka, and RabbitMQ, and client libraries for several languages.

Good

  • Free and released under the MIT license
  • Real-time geofence notifications for small or large datasets
  • Supports GeoJSON, geohashes, points, and other spatial data
  • Provides HTTP, WebSockets, and telnet access
  • Offers client libraries for multiple programming languages

Watch out

  • Self-hosted deployment requires installation
  • Password protection is off by default
  • Prometheus metrics endpoint is disabled by default

Who it suits

Tile38 suits developers building location-based services that need geospatial search or geofence notifications. It is also suitable for teams seeking a self-hosted, open-source option with Redis-compatible access and multiple client libraries.

Verdict

Tile38 combines geospatial indexing, geofencing, and several access protocols in a free, self-hosted package. Its default authentication and metrics settings are worth noting when planning a deployment.
