Download

The current version is v0.6.2. Every file below, with its SHA-256, is listed in checksums.txt; all versions live on the releases page.

Linux

On Arch and derivatives, from the AUR:

paru -S fastsapp-bin   # prebuilt
paru -S fastsapp       # builds from the release source
paru -S fastsapp-git   # builds from the latest commit

Elsewhere, a tarball with the binary, the desktop entry, and the icon:

It needs the libraries any egui app does, plus ALSA: libglvnd, libxkbcommon, wayland, libx11, and alsa-lib (on Debian or Ubuntu: libasound2, libgl1, libxkbcommon0, libwayland-client0). For colour emoji install noto-fonts-emoji (fonts-noto-color-emoji on Debian); the file picker uses xdg-desktop-portal.

macOS

One download for both Apple Silicon and Intel:

Open it and drag FastsApp to Applications.

First open on macOS

This build is not yet notarized with Apple, so macOS blocks it the first time. Recent macOS versions no longer let you bypass this with a right-click, so you open it once through Privacy & Security:

  1. Double-click FastsApp in Applications. macOS says it cannot be opened because Apple cannot check it for malicious software. Click Done (do not click Move to Trash).
  2. Open System Settings, then Privacy & Security.
  3. Scroll down to the Security section, find “FastsApp was blocked to protect your Mac”, and click Open Anyway.
  4. Authenticate, then click Open Anyway once more.

Or clear the quarantine flag instead:

xattr -dr com.apple.quarantine /Applications/FastsApp.app

The -r matters: it clears the flag from the files inside the bundle too.

Windows

The installer adds FastsApp to the Start menu and needs no administrator rights. Choose x86_64 for most PCs or aarch64 for Windows on ARM:

If you would rather not install anything, the same program comes as a zip: unpack it and run fastsapp.exe.

Either way, SmartScreen may warn about an unknown publisher on first run; choose More info, then Run anyway.
