Mergin Community Edition

The Mergin (opens new window) is a great companion to Mergin Maps Input as it provides seamless synchronisation of data between your phone/tablet, Mergin service and QGIS Desktop.

The good news is that Mergin CE is licensed as open source software and therefore it is possible to do your custom deployments.

GitHub

If you are interested in deploying Mergin CE, you can start by going to MerginMaps/mergin (opens new window) on GitHub and read instructions how to deploy it for your platform.
