Octi Desktop

Desktop companion for Octi — view your phone's modules and share files between your devices from your laptop. Talks to the existing Octi Server over the same end-to-end-encrypted protocol the Android app uses. No Google account, no separate backend.

Install

Two release channels are published as GitHub Releases:

• Stable — the build to use unless you have a reason not to.
• Canary — bleeding-edge build, rebuilt on every merge to main. Installs as a separate "Octi Canary" app that coexists with your stable install. Expect breakage.

Each release publishes installers for Linux, macOS (Apple Silicon + Intel), and Windows, plus a checksums.txt with SHA-256 hashes.

Linux

# Debian/Ubuntu
sudo apt install ./octi_<version>_amd64.deb
sudo apt install libsecret-tools     # required for OS keystore credential storage

# Fedora/RHEL
sudo dnf install ./octi-<version>.x86_64.rpm
sudo dnf install libsecret           # provides secret-tool

# Portable
chmod +x Octi-<version>-linux-x86_64.AppImage && ./Octi-<version>-linux-x86_64.AppImage
# or
tar xzf Octi-<version>-linux.tar.gz && ./Octi/bin/Octi

libsecret-tools is required for credential storage on Linux. Without it the app falls back to a per-launch passphrase prompt.

macOS

The current releases are unsigned — Gatekeeper will refuse to launch them on first try. To open:

1. Open the .dmg and drag Octi to /Applications
2. Right-click /Applications/Octi.app → Open → confirm in the warning dialog (once per machine)

Code-signing + notarization require a paid Apple Developer membership; until then, this is the workaround.

Windows

The MSI is unsigned — SmartScreen will warn on first launch. To install:

1. Double-click the .msi. SmartScreen pops up: click More info → Run anyway
2. Follow the installer prompts

Code-signing on Windows requires an Authenticode certificate; planned for a later release.

From source

Requires JDK 21 (the Gradle toolchain provisions it automatically; system Java just needs to be 17+).

./gradlew run                  # run from source

Link to your phone

1. On your Android phone, open Octi → Sync services → Octi Server → Generate linking code
2. On the desktop, paste the code into the welcome screen
3. Your devices appear in the dashboard within a few seconds
