About
latlng is an open-source spatial database written in Rust that supports indexing moving points, defining geofences as code, and streaming geofence events in real time. It can run as a native server with HTTP/JSON, WebSocket, and Cap'n Proto interfaces, or compile to WebAssembly to run directly in the browser via a Web Worker. It is MIT-licensed and supports features like spatial indexing, durable webhook delivery, replication, and JWT-based authentication.
Problem
Developers lack a lightweight, portable geospatial database that can run both as a native server and directly in the browser without a network dependency.
For
software developers building location-aware or geospatial applications
How it works
A single Rust core compiles to either a native binary or WebAssembly, enabling spatial indexing, geofencing, and event streaming natively or inside a browser Web Worker.
