Get Stegstr

The desktop app adds the feed, direct messages and relay sync to what the web version does. Builds are produced by the project's own CI from the tagged source and published with checksums.

Desktop app

macOS

Apple silicon and Intel. Unsigned build: the first time, right-click the app and choose Open, then confirm. After that it opens normally.

Stegstr-macOS.dmg

Windows

Installer or MSI. SmartScreen may ask once because the build is not code-signed; choose More info, then Run anyway.

Stegstr-Windows.exe .msi

Linux

AppImage runs anywhere (make it executable first); the .deb is for Debian and Ubuntu.

Stegstr-Linux.AppImage .deb

All releases with notes and SHA256SUMS.txt: github.com/brunkstr/Stegstr/releases.

Web version

stegstr.com/app embeds and detects in the browser, using the same code as the desktop app. Nothing is uploaded; the image is processed in the page and downloaded to your device. Relay features are desktop-only for now.

Command line

Node CLI, no install step

The robust hiding method, bundled with no runtime dependencies. Needs Node 18 or newer and nothing else, not even npm install.

git clone https://github.com/brunkstr/Stegstr.git
cd Stegstr
node dist-cli/stegstr.mjs selftest

Rust CLI with MCP server

JSON output on every command, stable exit codes, a channel calibration tool, and an MCP server for agents. Needs Rust.

cd Stegstr/src-tauri
cargo build --release --bin stegstr-cli
./target/release/stegstr-cli --help

Commands for both are on the CLI page; the agent workflow is on the agent guide.
