FROST-Server Build Status Codacy Badge Docker badge

FROST-Server Logo Certified OGC Compliant Logo

A Server implementation of the OGC SensorThings API. The FRaunhofer Opensource SensorThings-Server is the first complete, open-source official reference implementation of the OGC SensorThings API Part 1: Sensing 1.0. It also implements OGC SensorThings API Part 1: Sensing 1.1 and OGC SensorThings API Part 2: Tasking Core 1.1.


Instead of compiling the server yourself, you can also download pre-built war and jar files from:

Or you can use Docker.


Documentation can be found on the documentation site

Changes and Updates

See the Change Log.

Kubernetes (Helm) support

See helm/frost-server/ for how to use the FROST-Server Helm chart for a Kubernetes deployment.

Standalone Spring Boot

If you prefer to not use Tomcat, Kinota Server is a Spring Boot application that makes it easy to run Fraunhofer IOSB FROST-Server in cloud environments.


To compile FROST-Server you need to have a JDK and Maven installed.

  1. Checkout the project from github: git clone
  2. Go to the project root (The top-most directory with a pom.xml) cd FROST-Server
  3. Give the command mvn clean install. This should build the war and jar files in:
  • FROST-Server.MQTTP/target/
  • FROST-Server.HTTP/target/
  • FROST-Server.MQTT/target/
