Detailed Review
Mergin Maps treats field work as version control for geodata. Colleagues edit the same layers offline, the system merges their changes, and project history shows who changed what.
The company behind it, Lutra Consulting Limited, is registered in England and Wales under company number 09460334, which the site footer names as the developer of Mergin Maps.
Cost per contributor
The Premium plan is priced per contributor, with unlimited read-only members. Annual billing is €15.8 per contributor per month and monthly billing €19.5. Each contributor brings 1 GB of storage, and extra storage is €2.5 per GB.
Pricing examples on the page include a free NGO plan for organisations with revenue up to $30k.
Publishing and enterprise options
A newer feature publishes a QGIS project online through a simple URL, and the site lists web maps and an API. Enterprise adds a choice of data residency, custom branding and domain, a dedicated account manager and an SLA.
Licensing documents
Its licensing page separates the cloud service terms, a self-hosted service and a Community Edition. The mobile app repository on GitHub carries the GPL-2.0 licence.
Limitations to Consider
Lutra is a UK company, so the contract falls under UK rather than EU law. Prices are per contributor, which grows with team size, and the default cloud region is not stated on the pages we read. As with QField, the workflow is built around QGIS projects.
Who Should Use Mergin Maps
Field teams in utilities, forestry or ecology that want per-contributor pricing and a QGIS-centred workflow with a UK supplier.
