TinyCld 是一款快速、精简且开源的替代方案，旨在取代 Google Workspace 和 Microsoft 365 等大型科技套件。它并非基于现有服务进行封装，而是从零构建，为电子邮件、文件、日历和联系人提供了一个真正私密、用户自主的基础设施。主要特性包括： * **高性价比与灵活性：** 完全免费使用，无按用户收费或高级会员层级。可通过单个 Docker 镜像轻松部署在您自己的服务器（例如 5 美元的 VPS）或托管选项上。 * **隐私至上：** 无遥测、无追踪像素、无数据挖掘，TinyCld 确保您的信息始终归您所有。它内置服务器端图像代理，以防止发件人追踪。 * **标准化兼容性：** 支持 IMAP、SMTP、CalDAV、CardDAV 和 WebDAV 等原生协议，可与 Apple Mail、Thunderbird 及移动客户端等标准工具无缝集成。 * **协作功能：** 支持多组织协作，具备共享资源功能，并可在网页和移动平台上实现实时更新。通过消除供应商锁定和“回传数据”行为，TinyCld 提供了一个安全、可自托管的生态系统，让您能够完全掌控团队的数据。

Own your data

Your emails, files, and contacts live on your server. No data mining, no ads, no lock-in. Export anything, anytime.

Deploys anywhere

A single Docker image runs on a $5 VPS, your homelab, or a Dokku one-liner. Healthchecks and Let's Encrypt are baked in - no ops team required.

Private by default

No telemetry, no tracking pixels.

Self-host on your own server and TinyCld never phones home - no analytics, no crash pings, no metered usage reports. External email images are proxied through your server with a scoped token, so senders can't see your IP, read receipts, or user agent. Big tech sees nothing, because nothing is sent.

Server-side image proxy for HTML email
Invite-only signup - no public account creation
One binary, one SQLite file, one place to audit

Native protocols

IMAP, SMTP, CalDAV, CardDAV, WebDAV - use Apple Mail, Thunderbird, any CalDAV client, or mount your drive as a network folder.

Multi-org

Users can belong to multiple organizations with different roles. Shared calendars, contacts, mailboxes, and files within org boundaries.

Web + Mobile

One app for web, iOS, and Android - plus standard protocols so Apple Mail, Thunderbird, and Finder just work alongside.

Real-time

Live updates across all apps via server-sent events. No polling, no manual refresh - changes from other users and devices appear instantly.
