Tools, services and organisations that do less harm than the default choice, in 43 categories. We’re re-checking every entry against our checklist, one category at a time.
Tools for private file sharing, syncing and cloud storage, from encrypted cloud drives to software you run on your own devices or server. We look for end-to-end encryption or self-hosting, open-source code and owners who are open about how they make money.
Our top picks: Syncthing, open-source sync between your own devices with no cloud copy, run by a Swedish non-profit. And Nextcloud, an open-source file, calendar and office hub from Stuttgart that you host yourself or use through a provider; the company is funded by enterprise subscriptions.
How we choose: we check every tool against the 6 principles in our manifesto: who owns it and how it makes money, what it collects, how it treats people, honesty, openness and staying power. This list was last checked on 13 October 2026.
