NextGIS Web vs QGIS Server
Executive summary
For teams that want a complete Web GIS platform with built-in data storage, user management, collaborative editing, version control, QGIS integration and ready-to-use web maps, NextGIS Web is the more complete solution.
QGIS Server could be a choice when you need to publish QGIS projects as OGC services inside a custom architecture and are prepared to build or integrate the surrounding components yourself.
About the products
NextGIS Web is a full-featured Web GIS platform that combines geospatial data storage, user and permission management, web maps, APIs, and tight QGIS integration in a single system. It is designed to support collaborative workflows out of the box.
QGIS Server is an open-source OGC server component that renders and publishes QGIS projects via WMS, WFS, WCS, OGC API. It uses QGIS Desktop project files (.qgz) as its configuration source and is typically deployed as a backend service within a larger GIS stack, not providing data storage and user management.

Architecture and positioning
QGIS Server
QGIS Server is primarily a rendering and OGC publishing engine. It uses QGIS project files for configuration, publishes layers through OGC services and relies on external databases (e.g., PostGIS), web clients (e.g., OpenLayers, Leaflet), and custom authentication layers.
It is most commonly used when you already use QGIS Desktop heavily and are building a custom GIS web application. It does not provide built-in data lifecycle management, web-based dataset administration, native collaborative workflows and platform-level APIs for users and resources.
NextGIS Web
NextGIS Web is designed as an integrated Web GIS environment. It includes:
- Centralized geospatial data storage
- Built-in user, group, and permission management
- Web Map configuration and publishing
- REST API covering all core functionality
- Versioned vector layers with edit history
- Native desktop integration with QGIS suitable for teams
As a result, NextGIS Web can be deployed as a complete system, without requiring additional components for common workflows.
At the same time, NextGIS Web also could serve as a GIS backend for custom GIS development.
Data storage and management
QGIS Server does not store data itself. It publishes data from external sources such as databases, vector or raster files. Data lifecycle management is handled outside QGIS Server.
NextGIS Web includes internal vector and raster storage, allowing datasets to be uploaded, edited, versioned, and published directly within the platform. This simplifies administration and reduces the number of moving parts in typical deployments.
Editing and collaboration workflows
With QGIS Server, editing is possible via WFS-T, but it requires properly configured external databases, doesn’t have built-in version control or native conflict resolution. Enterprise-grade collaboration depends entirely on database configuration.
NextGIS Web provides native multi-user collaborative editing with:
- Concurrent edits from QGIS and web clients
- Actionable history for vector layers
- Conflict detection and resolution mechanisms
This makes it suitable for teams working on shared datasets.
QGIS integration
With QGIS server integration is direct but service-based:
- QGIS Desktop project → published via OGC
- Interaction limited to service layer
Good for publishing maps; limited for platform-level management.
NextGIS Web offers native QGIS integration via NextGIS Connect, enabling:
- Direct access to server-side resources
- Editing versioned layers from QGIS
- Managing permissions and metadata
- Synchronizing projects seamlessly between desktop and server
This integration is designed for daily production workflows in QGIS-centric teams.
APIs and extensibility
QGIS Server has strong OGC standards support, but limited API beyond services. It is best suited for standards-compliant service publishing.
NextGIS Web provides a complete REST API, meaning that anything available through the web interface can also be automated or integrated programmatically. This allows NextGIS Web to act as both a GIS backend and an application platform.
When to choose which
Choose QGIS Server if:
- You are building a custom GIS architecture
- Data storage and authentication are managed elsewhere
Choose NextGIS Web if:
- You want an integrated Web GIS platform
- You work primarily with QGIS
- You need collaborative editing and actionable data history
- You want to minimize custom backend development
- You need a single system for data, services, users, maps, and APIs
Frequently asked questions
How do QGIS Server and NextGIS Web provide a web map viewer/editor?
QGIS Server focuses on data publishing and relies on external web clients for end-users to visualize and edit the data. NextGIS web has built-in mechanisms to publish rich web maps.
Can both solutions be deployed on-premise?
Yes. Both NextGIS Web and QGIS Server support on-premise deployment. NextGIS offers several on-premise editions ranging from a single-server setup to multi-server configurations for enterprise and government deployments.
Is NextGIS Web open source?
Yes. NextGIS Web is an open-source Web GIS framework.
Can I build custom applications on top of both?
Yes. Both expose REST APIs and support OGC protocols that external applications can build on. NextGIS Web additionally provides a complete REST API covering all platform functionality – data, users, permissions, and maps – making it suitable as a full application backend without additional middleware.
Are NextGIS Web and QGIS Server both free?
Both are open source and free to use. QGIS Server is community-maintained. NextGIS Web is open source with a self-hosted option, and also available as a cloud-hosted SaaS with both free and paid plans provided by those who developed the product.
Can field teams collect data using QGIS Server or NextGIS Web?
QGIS Server has no native mobile data collection capability – this would require building a custom solution on top of OGC APIs. NextGIS Web integrates natively with a mobile app for offline field data collection that syncs automatically when connectivity is restored.
How difficult is it to migrate from QGIS Server to NextGIS Web?
Since QGIS Server is based on QGIS projects, which can be easily imported into NextGIS Web using the NextGIS Connect module, switching from QGIS Server to NextGIS Web is generally very straightforward.
