What OpenFMS is

OpenFMS is a free, open-source fleet management system for real-time telematics. It provides GPS tracking and geofencing through a web dashboard aimed at fleet dispatchers. The dashboard is built with React and is described as responsive and customizable. OpenFMS also offers REST and gRPC interfaces and describes its API as full, giving developers ways to connect with the system. Its backend is built with Go; the product says it can handle thousands of concurrent TCP connections and real-time GPS data streams with minimal CPU use. OpenFMS runs on servers managed by its users and can be deployed with Docker. PostgreSQL is part of its advertised deployment stack. Its listed platforms are API, self-hosted, and web. The product is designed for developers and modern fleet dispatchers who want to deploy and work with a telematics system. Because hosting is self-managed, teams use their own servers for deployment. OpenFMS combines tracking, dispatcher-facing controls, and APIs in an open-source system that is available at no charge.
