In the Netherlands municipalities have been collaborating for years already to build an open source ecosystem: https://commonground.nl/

We have 342 municipalities, all buying the same apps (from 3 or 4 vendors) to deliver basic services to their citizens. Common Ground aims to replace all of those with open source solutions.

Hey, I would love to contribute to this project. Is there a list of repo's I can take a look at and contribute?

I see some communities, seems like each community has their own setup, some of them have github links.

The way they go about this is still a bit weird / government like. Individual municipalities write tenders for software companies to contribute to these projects. The Vereniging Nederlandse Gemeente is hosting the specific committees that are in charge of product vision / architecture. But I am not sure if there is a way for individuals to contribute to these projects right now. So the source is Open Source, the process very much not yet.

If you are Dutch and looking to work on awesome gov-tech send me a DM.

https://govstack.global/ is trying to find common grounds, but it doesn't coordinate any government work

If by "coordination" you mean central planning, not.

There are things such as sharing best practices and other resources. An example is https://standard.publiccode.net/ and https://new.digitalpublicgoods.net/ .

And of course many efforts towards a shared funding infrastucture, see also https://fosdem.org/2026/schedule/event/KES3TH-funding_europe...
