Host your own email, files, calendars, and passwords on a single server with YunoHost, a server operating system that puts every app behind one web admin and one shared login. Browse a catalog of more than 500 apps, such as Nextcloud, WordPress, and Vaultwarden, filter by quality level, and install in a few clicks, or paste a Git URL for a custom app. Each person signs in once at a portal that shows a tile for every app they may open, and apps with single sign-on skip their own login screen. Groups and per-app permissions control access, including public access for visitors, and the Admins group adds web admin, SSH, and sudo. A full mail stack handles incoming and outgoing email per domain with DKIM signing, and Let's Encrypt certificates renew automatically. The domain screen suggests the DNS records you need and can push them to a supported registrar's API, while free .nohost.me, .noho.st, and .ynh.fr subdomains configure themselves. Backups bundle system settings, mail data, and chosen apps into downloadable archives that can be restored selectively from the admin or the command line. Twice a day a built-in diagnosis checks DNS records, mail setup, and system resources, then emails the admins if anything needs attention, with a firewall editor and fail2ban protection alongside. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

When a regulatory audit, legal discovery request, or employee offboarding requires years of verifiable email records, Open Archiver provides a tamper-evident, self-hosted vault for every message across your organization. Connect Google Workspace domains, Microsoft 365 tenants, personal Outlook OAuth accounts, or standard IMAP servers for continuous background synchronization, or upload historical PST, MBOX, and zipped EML archives in bulk. Every ingested message is deduplicated, compressed, and stored in standard EML format on local disks or S3-compatible object storage while SHA-256 cryptographic hashes verify file authenticity on demand through built-in Integrity Reports. Instant full-text search scans both message bodies and attached PDF or DOCX documents, letting compliance teams reconstruct complete conversation threads and enforce automated retention policies. Granular access control backed by an AWS IAM style policy engine, TOTP two-factor authentication, and an immutable audit trail keeps sensitive correspondence locked down.
