Desktop app
Use Astrofox offline with native video export and desktop integration.
The Astrofox desktop app packages the same React interface as the web app in Electron. Projects move between web and desktop without conversion.
Download current installers from the download page. Each link points at the latest GitHub release.
Why use desktop#
- Work without a network connection after installation
- Render offline MP4 video through the bundled ffmpeg binary
- Choose x264, x265, NVEnc, or WebM encoders
- Choose an absolute export location and reveal the result in its folder
- Capture desktop audio where the operating system allows it
- Receive application updates from published GitHub releases
Platform packages#
Astrofox builds are available for Windows x64, macOS Intel and Apple Silicon, and Linux x64. A release can include Windows installers, macOS DMG or ZIP files, and a Linux AppImage.
File access and permissions#
Astrofox uses browser-style file pickers for projects, audio, images, and video. Native dialogs are reserved for workflows that require a real path, such as ffmpeg output.
macOS may request microphone and screen-recording access for live input and desktop audio capture. Grant only the permissions needed by your workflow.
ffmpeg fallback#
Desktop packages normally include ffmpeg. If it is missing or unavailable,
Astrofox falls back to browser MediaRecorder export. The available format
then depends on the embedded browser rather than the desktop encoder list.
Update the app#
Open Settings at the bottom of the action rail to check for updates. When an update has downloaded, a restart button appears in the app bar. The app installs it after the release has been published on GitHub.
The desktop renderer is intentionally isolated from the operating system. It uses a narrow preload bridge for window controls, ffmpeg, temporary files, and post-export integration.
