Open alternatives to Microsoft & Google
You don't have to run your business on the terms of two American advertising companies. There's a full, mature open-source stack that covers email, files, documents, chat, calls and projects — and we run it for you.
What you actually need — and what replaces it
A pragmatic map of the open-source tools we deploy in production. Not toys, not side projects — software that runs entire companies.
Mailcow & Mailbox.org
Real, standards-based email on your own domain. IMAP, SMTP, spam filtering, calendars and contacts — without your inbox feeding an ad engine.
Nextcloud
Files, sharing, sync and a full collaboration suite. Desktop and mobile clients, end-to-end encryption, and admin controls that actually behave like admin controls.
Collabora & OnlyOffice
Real-time editing of documents, spreadsheets and presentations — fully compatible with Office formats, hosted inside your Nextcloud.
Mattermost & Rocket.Chat
Team chat with channels, threads, integrations and search — without exporting every conversation to a US hyperscaler.
Jitsi & Nextcloud Talk
Browser-based video calls and meetings with screen sharing, recording and dial-in — no installs, no per-seat licenses.
OpenProject
Project management, roadmaps, Gantt charts and time tracking. The grown-up alternative to spreadsheets and Microsoft Project.
Open calendars & contacts
CalDAV and CardDAV that work with every modern client — including Outlook, Apple Mail and Thunderbird. Shared team calendars without lock-in.
Search you can trust
Self-hosted Searx or a paid relationship with a European search provider — instead of training someone else's ad model.
