TinyCld launches an open‑source, self‑hosted office suite that bundles email, calendar, contacts, drive and document editors into a single Docker image. Mail supports threaded conversations, labels and IMAP/SMTP; Calendar uses CalDAV with recurring events and RSVP; Drive offers WebDAV storage with versioning and role‑based permissions. The suite also includes a spreadsheet module with formulas, CSV/XLSX import and mobile‑first editing.

Unlike Google Workspace or Microsoft 365, TinyCld costs $0 per user and imposes no seat‑based fees. A single SQLite database backs the stack, while native protocols let existing clients like Apple Mail or Thunderbird connect without extra software. Deployment runs on a $5‑month VPS; health checks and Let’s Encrypt are built‑in, eliminating ops overhead. It provides audit logs and role‑scoped sharing to meet compliance needs.

The TinyCld iOS app, built with Expo Router, mirrors the web interface and delivers native push notifications from a user‑controlled server. Export tools parse Google Takeout archives in a web worker, allowing seamless migration of mail, contacts and calendars. With no telemetry, open‑source licensing and a single‑binary distribution, the suite lets teams replace SaaS stacks with a private cloud today.
