Signal K Server

Signal K Server is an open-source Node.js application that functions as a central data hub for marine electronics, implementing the Signal K standard for boats. It aggregates data from various sources such as NMEA 0183, NMEA 2000, and SeaTalk, then makes this information available to other applications and devices via WebSockets and HTTP APIs. Currently at stable version 2.25.0, the project maintains an active release cadence with frequent minor and patch updates, often including beta versions, addressing features, fixes, and performance improvements. Key differentiators include its role as a vendor-agnostic data standard implementer, its extensibility through a robust plugin architecture, and its ability to run efficiently on embedded hardware like Raspberry Pis and Victron Cerbo GX devices. It enables a wide range of functionalities such as serving as a wireless AIS and navigation hub for popular marine apps, providing anchor watches, functioning as a weather station, and generating automatic logbooks.
