Who We Are

The Free and Open Source universal marine data exchange

Signal K is about publishing a common modern and open data format for marine use. A format for the modern boat, compatible with NMEA, friendly to WiFi, cellphones, tablets, and the Internet. A format available to everyone, where anyone can contribute.

Open Source

Yup. We publish all source code under the Apache License, Version 2.0 and everything else, like protocols and interface descriptions, under the Creative Commons CC-BY-SA license.

That means that it is open source, but friendly to companies that want to use it in closed source applications or hardware. As long as you contribute back we're happy.
