Kolab Now – European email provider
A fully open-source email and collaboration suite hosted in Switzerland. Email, calendars, contacts, tasks, file storage, and collaborative editing - all built on free software and operated under strict Swiss privacy law, with no ads and no tracking.
Quick facts
The entire groupware stack – mail, calendar, contacts, tasks, file storage and collaborative editing – is built on open-source software you could self-host yourself if you wanted to leave.
There's no free tier, pricing starts at CHF 4.55/month for email alone, and the interface feels more utilitarian than Proton's polished apps.
Why does it score 97?
Incorporated in Zürich, Switzerland – an EFTA country rather than a full EU member state.
Independently owned by Apheleia IT AG, with no outside investors.
Kolab Now runs entirely on its own infrastructure in Switzerland rather than a third-party cloud.
Fully open source and GDPR-compliant – the entire stack can be self-hosted, so you can migrate away freely if you ever want to.
