Traccar
A mature open-source GPS tracking platform supporting 170+ device protocols. Standout trait is its protocol breadth for real-world fleet/asset tracking hardware.

⚙ Full Stack
Java application (Netty-based) handling dozens of concurrent TCP/UDP device protocol listeners, backed by H2 (default) or MySQL/PostgreSQL, with a web frontend for fleet management and a REST API.
📈 Scaling Analysis
A single JVM instance handles a large number of concurrent device connections well due to Netty's async I/O, but horizontal scaling across multiple app instances isn't natively supported — it's vertical-scale-first.
🚀 Running on Nexlayer
One pod for the Traccar server (exposing many device-protocol ports) plus a postgres pod (postgres.pod:5432) for production data safety instead of the default embedded H2. Mirror the JVM base image via mirror.gcr.io.
