QGIS Sustainability Initiative – Annual Report

What is the QGIS Sustainability Initiative?

At OPENGIS.ch, we believe that the long-term health of the QGIS ecosystem depends on more than just adding new features. Critical work like bugfixing, code reviews, codebase maintenance, and quality assurance often goes unnoticed, yet it is essential to delivering the stable, reliable software that thousands of organisations depend on every day. That is why we launched the QGIS Sustainability Initiative (#sustainQGIS). For every support contract of more than 10 days, we donate development time to the initiative. In addition, all unused hours at the end of the year of each contract are also donated. This ensures that buying an OPENGIS.ch support contract directly helps enable the long-term, sustainable development of the QGIS and QField ecosystem.


2025 at a glance

In 2025, our team invested a total of 168 hours into the QGIS Sustainability Initiative, spread across five key areas of work. On the wider QGIS project, we contributed 553 comments and 294 merged pull requests throughout the year.

*In addition to these sustainability hours, OPENGIS.ch dedicated 105 hours to QGIS bugfixing funded by QGIS.org.

OPENGIS.ch on QGIS in 2025

Beyond the sustainability initiative, OPENGIS.ch had a significant presence in the QGIS codebase throughout 2025. In total, our team contributed 773 commits, 221 merged pull requests, 384 PR reviews, and helped close 122 bugs, plus 126 hours of dedicated bugfixing (21h from the sustainability initiative + 105h funded by QGIS.org).


Why It Matters

Every hour invested in the QGIS Sustainability Initiative strengthens the foundation that thousands of organisations rely on. By choosing an OPENGIS.ch support contract, you are not only getting expert support for your projects, you are directly contributing to a healthier, more sustainable open-source GIS ecosystem.

Sustainability initiative: what is it and why we do it?

At OPENGIS.ch, we create open-source software.
We are contributors, maintainers, and in the case of QField, the team that builds it.

That comes with a responsibility we take seriously: giving back.

“Give back” is not a slogan. It is our first core value, and the very reason the sustainability initiative exists.

Open-source is a garden. If you eat from it, water it, and keep seeding.

What is the #sustainQGIS initiative?

Open-source software has a well-known problem: the work that keeps it healthy is largely invisible. Bug fixes, code reviews, refactoring, test coverage, onboarding new contributors: none of these appear in a feature list, but without them, the software eventually degrades. Proprietary projects can budget for this work directly. Open-source projects mostly rely on whoever finds the time.
We wanted to change that, at least in our corner of the ecosystem.


The model is simple. For every support contract we sign that exceeds 10 days, we donate a portion of those days to the initiative. Any unused contract hours at year-end also flow in. That pool of time gets spent on exactly those invisible tasks: triaging and fixing bugs that affect stability, reviewing pull requests so good contributions actually land in the codebase, and doing the unglamorous maintenance work that keeps QGIS’s core solid.

Why we do it

We built a successful company around QGIS and QField. We write code (custom features, plugins, processing algorithms, entire applications) on top of these platforms every day. When a client needs something that cannot be done out of the box, we build it. And we build it inside the project whenever that makes sense, not in a private fork that nobody else benefits from.

Pushing changes upstream instead of maintaining private forks, sponsoring the QGIS project financially, and donating hours are all expressions of the same logic: the ecosystem is a shared asset, and shared assets need shared investment.

I chair the QGIS.org foundation, so I see directly how much the project depends on companies like ours showing up. A bug that slips through costs every QGIS user time. A code review that never happens means a useful feature sits in limbo for months. And a small group of core maintainers carrying the full load eventually burns out. These are not abstract problems. They affect users and the community on a daily basis.

What this means when you work with us?

When you sign a support contract with OPENGIS.ch, you are not just buying expert help with QGIS and QField. A slice of that contract goes back into the project itself. Your investment in solving your own GIS challenges also helps keep the platform reliable for everyone.

We think that is a good deal. It is the way we want to do business.

If you want to know more about the initiative or are ready to make a difference, get a support contract.
