Beta
A real document editor — not a textarea in a tab. Rich formatting, tables, comments, suggesting mode with accept/reject, and live CRDT collaboration. Full-fidelity .docx and Markdown round-trips. Mobile-native: format and edit from your phone without fighting the keyboard.
Feature complete · Lightly battle-tested
Beta
Spreadsheets that hold up on a phone. Formulas, named ranges, pivot tables, conditional formatting, sort + filter, comments, and real-time co-editing on top of Drive. CSV and .xlsx import/export with formatting preserved, so it actually plays nicely with whatever your team already uses.

Migrate
Export your Google data. Drag the ZIP onto TinyCld.
We parse .mbox, .ics, and .vcf in a
web worker, dedupe contacts by vCard UID, merge calendars
by ICAL_UID, and drop your files back into their original folders.
Download your archive from Google Takeout Mail, Calendar, Contacts, and Drive in one bundle.
Drop the .zip into TinyCld - no unpacking Parsing happens in a web worker, so the UI stays snappy even at 20 GB.
Walk away. Re-imports are idempotent. Contacts dedupe by vCard UID, events by ICAL_UID, calendars reuse by name.
$0 / user
No per-seat pricing, no premium tiers, no surprises. TinyCld is open source under a permissive license. Self-host it on a $5/month VPS or use our hosted option.
Google Workspace $7.20/user/mo
Microsoft 365 $6.00/user/mo
TinyCld Free
Your emails, files, and contacts live on your server. No data mining, no ads, no lock-in. Export anything, anytime.
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
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.
IMAP, SMTP, CalDAV, CardDAV, WebDAV - use Apple Mail, Thunderbird, any CalDAV client, or mount your drive as a network folder.
Users can belong to multiple organizations with different roles. Shared calendars, contacts, mailboxes, and files within org boundaries.
One app for web, iOS, and Android - plus standard protocols so Apple Mail, Thunderbird, and Finder just work alongside.
Live updates across all apps via server-sent events. No polling, no manual refresh - changes from other users and devices appear instantly.

01 You write the directories listed in your manifest.
02 pnpm install links it as a workspace member.
03 The generator stitches everything in - routes, types, server, migrations.
04 Your package is alive on web and native, with a working admin UI.
For developers
The scaffolding CLI sets up a sibling repo with a working manifest,
an example screen, and the symlink wired into a running app shell.
From npm create to a live route in your browser.
