NNeutrino
Open source · MIT licensed · End-to-end encrypted
Your whole office.
On your own server.
Drive, Docs, Sheets, Slides, Notes, Photos, Calendar, Diagrams and Drawings — nine apps in a single Rust binary. End-to-end encrypted, works offline, and runs on hardware you control.

The suite
Nine apps that already work together
Not a file host with an editor bolted on. Every app writes to the same drive, shares the same search index, and is encrypted with the same key.
Every file, one place
Streaming uploads up to 10 GB, nested folders, tags, stars and shortcuts. Quick access surfaces what you starred; the grid, list and detail views are all one click away.
- Large grid, small grid and detailed list views
- Folders, tags, colour labels, shortcuts and bulk actions
- Trash with restore, plus a full activity trail on every file
- HTTP Range downloads, so an interrupted transfer resumes
Documents that write like paper
A full rich-text editor with a live outline, page rulers, styles and a word count — collaborative in real time and encrypted before a single byte leaves the browser.
- Real-time co-editing with presence
- Automatic outline from your headings
- Version history with restore
- Import and export Word, PDF and plain text
Spreadsheets with real formulas
A virtualised grid that stays fast at scale, with a formula engine, cross-sheet references, named ranges, conditional formatting and charts.
- Formulas, named ranges and cross-sheet references
- Currency, percent, date and custom number formats
- Charts, conditional formatting and filters
- Round-trips with .xlsx
Decks without the ceremony
Pick a layout, type, present. Master slides and themes keep a deck consistent, and speaker notes travel with it.
- Layout and theme library, plus master slides
- Speaker notes and presenter mode
- Import and export PowerPoint
- Real-time co-editing with presence
Quick thoughts, kept private
Block-based notes that sync live across every device you own. Notes are end-to-end encrypted, so the server stores ciphertext and nothing else.
- Live sync across devices and tabs
- End-to-end encrypted — the relay never sees content
- Markdown-style inline formatting
- Import straight from Google Keep
Your library, not theirs
Albums, favourites, archive and memories over the same storage as the rest of your drive — with people grouping that runs against your own data.
- Albums, favourites, archive and memories
- People grouping and suggestions
- Backed by the same Drive storage and quota
- Import your Google Takeout archive
Schedules, reminders and tasks
Month, week and agenda views with recurring events, reminders and task lists in the sidebar. Sync with Google or Outlook, or import an .ics and keep it local.
- Month, week and agenda views
- Recurring events, reminders and browser notifications
- Task lists alongside the calendar
- Google and Outlook sync, plus ICS import and export
Diagrams and Drawing round out the nine — flowchart, UML, BPMN, ERD and cloud shape libraries, plus a freehand canvas, both saving into the same drive.
What you get
Built for real work
Everything below is shipped and running today — not a plan.
Encrypted, with no way around it
Every write to your drive is encrypted in the browser first — documents, notes, uploads, photos and imports alike. There is no plaintext path left to fall back to, so a server operator, including you, only ever sees ciphertext.
Keys you actually control
No passphrase to forget: your keyring unlocks with the device. Add a phone by scanning a PIN-protected code, and rotate your identity whenever you like — retired keys are archived so older files keep opening.
Real-time collaboration
Docs, Sheets, Slides and Diagrams carry live presence and co-editing. Notes sync between your own devices the moment a save lands.
Search across everything
One index spans every app. Because content is encrypted, search runs locally in your browser — the server is never asked what you were looking for.
Works offline
Keep editing on a plane. Writes queue locally and reconcile when you reconnect, on the web app and the native clients alike.
Sharing and permissions
Share links with roles and expiry, shared drives for teams, access requests, comments and an activity trail on every file.
Bring your data with you
Import a Google Takeout archive straight from the browser — Keep becomes Notes, Drive documents and spreadsheets become Docs and Sheets, Google Photos becomes Photos. Folder tree intact, and every file keeps the dates it already had.
One binary, no dependencies
A Rust server that embeds its own migrations and serves the web app. SQLite by default — no external database to run before you start.
Admin you can actually run
Per-user quotas, upload caps, TOTP two-factor, session management, feature flags and an audit trail, all in the admin panel.
Clients
On the web, on your Mac, in your pocket
Native clients speak the same encrypted protocol as the web app, so a file you edit on your phone is the same file your desktop syncs a second later.
macOS desktop
AvailableA native menu-bar app with a Finder File Provider extension, so your drive is a folder like any other and syncs in the background.

In developmentThe mobile file browser — browsing, uploads, viewers, version history, offline files, search and photo sync, with the key imported by scanning the code from the web app. In testing ahead of release.
Android, Windows and Linux clients are on the roadmap — see what's next.
Self-host
Your server. Your rules.
Deploy Neutrino on any Linux server, VPS, NAS or Raspberry Pi. One binary backed by SQLite — migrations run themselves on first boot, and the same process serves the API and the web app.
- Your data never leaves your servers
- No per-seat pricing and no vendor lock-in
- Set your own quotas, retention and policies
- Runs on a VPS, a NAS or a Raspberry Pi
- Single binary with SQLite — no external database
- MIT licensed, so you can fork it and keep going
