Your phone, laptop and desktop, as one.
Saiph links your Android phone to every computer you own, the way Apple devices work together. Texts, calls, notifications, clipboard, photos and files follow you from screen to screen, over a private connection you own.
Development preview. Public downloads and paid Hosted are not open. GitHub access is currently limited to invited collaborators.
Illustrated feature preview
Your devices, working together.
Everything your phone knows, on the screen you're using.
These animations illustrate the intended experience. Release builds and acceptance checks are still in progress.
Private by design
Every device has its own key. Pairing uses one-time invitations, and you can revoke a lost device instantly.
Updates itself
Check for updates from Settings. Upgrades keep your data, back up first and roll back if something fails.
Releases are being prepared.
Public downloads are not available yet. The source repository is private while we finish release and security checks. Explore self-hosting and the Hosted design.
Per-user installer. No admin rights needed; uninstalling never touches your data.
Download for Windows →Extract and run orion/install.sh. Installs to your home folder, adds a launcher.
Pair by scanning your invitation QR code. Every permission is asked for, never assumed.
Download for Android →Public releases will include SHA-256 checksums and their exact source revision. All releases
Self-hosting, with managed hosting in development.
Saiph needs a small always-on Hub that your devices talk through. The self-hosted design runs on your own server. Managed hosting is being prepared and subscriptions are not open.
Self-hosted
Your server, your network, your data. No account with us, no licence check, nothing phoning home.
- Every feature, no limits
- Runs on a Raspberry Pi, home server or any Ubuntu/Debian box
- Guided installer, one-click updates with rollback
- Optional synced Cloud folder and encrypted backups
Saiph Hosted Coming soon
The goal: a dedicated Hub with content encrypted by your devices. App integration and independent security review are still required before launch.
- Planned: encryption on your devices before relay
- Planned: a dedicated deployment per customer
- Designed for approval by an existing trusted device
- Export and migration are launch requirements
Your phone is the most personal thing you own. We treat it that way.
Saiph was built around one rule: your messages, notifications and files belong on your devices, not on someone else's server.
- Device keys never leave the device. Each phone and computer generates its own keys and stores them in the OS keystore (Windows DPAPI, Linux Secret Service, Android Keystore).
- Signed, replay-proof requests. Every request is signed by the sending device, with timestamps and one-time nonces, so it can't be forged or replayed.
- Private self-hosted network. The self-hosted Hub is intended for your private mesh. Hosted development uses an authenticated HTTPS API.
- Revoke in one click. Lost a laptop? Remove it and it's cut off immediately.
- Agents ask first. Automations and assistants get finite, scoped access, and anything that leaves your phone waits for your approval.
- Review before release. Source publication, signed release verification and independent Hosted security review remain launch work.
Source publication is planned.
The desktop app and Hub are licensed AGPL-3.0; the Android app is GPL-3.0. The repository remains private during development. Public source and download access will be announced separately.
