Awesome Swiss Data Sources

This file presents some of the main repositories of data in Switzerland in a brief overview, that we have tailored for participants of the GovTech Hackathon. Every source listed on this page has an openly accessible API - which may just require registering for an API key - whose machine-readable endpoint we link to directly. Earlier versions of this page can be found at forum.opendata.ch and make.opendata.ch. Check out Awesome Open Government Data Switzerland for a more comprehensive list of Open Government Data (OGD) portals, websites, APIs, tools and other related resources in Switzerland and abroad.
