TinyCloud - Open-source self-hosted productivity suite with mail, docs, spreadsheets, and drive.

Open-source self-hosted productivity suite with mail, docs, spreadsheets, and drive.

What it does

TinyCloud is an open-source, self-hosted productivity suite that includes mail, calendar, contacts, drive, text documents, and spreadsheets. It is designed to be deployed on your own infrastructure, giving you full control over your data. The suite supports standard protocols like IMAP, SMTP, CalDAV, CardDAV, and WebDAV, allowing you to use your favorite desktop or mobile clients alongside the web and iOS apps.

Who it is for

TinyCloud is built for teams and individuals who want to move away from subscription-based productivity tools like Google Workspace or Microsoft 365. It is particularly suited for organizations that prioritize data privacy, want to avoid per-user pricing, and have the technical capability to self-host a Docker container. Developers can also use TinyCloud as a platform to build custom apps on top of its foundation.

Why it matters

TinyCloud addresses the growing demand for privacy-focused, self-hosted alternatives to mainstream productivity suites. It is free forever with no per-seat pricing, and it runs on a single Docker container that can be deployed on a $5/month VPS. The suite is built from the ground up, not a wrapper around other services, and it includes real-time collaboration, native protocols, and a mobile app. The project is open source under a permissive license, and it offers a migration tool to import data from Google Takeout.

Launch signal

TinyCloud launched on the App Store in early 2025 with an iOS app that connects to your self-hosted server. The project was also featured on Hacker News as a Show HN, indicating early community interest. The website highlights that the text and calc apps are "feature complete · lightly battle-tested," suggesting they are in beta but functional.

Brand and naming

The name "TinyCloud" suggests a lightweight, personal cloud solution, contrasting with the "big cloud" providers. The tagline "Your cloud, your rules" reinforces the message of control and privacy. The branding is clean and developer-friendly, with a focus on open source and self-hosting.
