Tile38 is an open-source, in-memory geospatial database and real-time geofencing server written in Go. It supports spatial indexing of points, bounding boxes, Geohashes, XYZ tiles, and GeoJSON, with geofence notifications delivered via webhooks or pub/sub channels.

Use cases

• track vehicle fleet locations in real time
• send alerts when a device enters or exits a geofence
• find nearby points of interest by radius
• query which objects intersect a polygon area
• store and search GeoJSON location data
• build location-based notification pipelines with webhooks

When to choose

• you need real-time geofencing with webhook or pub/sub notifications
• you want a fast in-memory spatial index with Redis-like protocol support
• you need leader/follower replication for a location data store
• you want a self-contained server with CLI, HTTP, and websocket access

When to avoid

• you need durable disk-first storage with full ACID transactional guarantees
• your dataset is primarily relational rather than geospatial
• you need heavy GIS operations like raster processing or coordinate reprojection
• you want a managed cloud database without self-hosting
