Windows (native)
- x86_64 β
ffl-v3.9.11-x86_64-windows.zip
Unzip to getffl.exe.
Linux (native)
We publish two glibc baselines. Pick the highest baseline that does not exceed your system glibc:
-
glibc 2.39+ β smaller & faster
ffl-v3.9.11-manylinux_glibc2.39-x86_64-linux.tar.gz- Best for newer distros (e.g., Ubuntu 24).
-
glibc 2.28+ β widest compatibility
ffl-v3.9.11-manylinux_glibc2.28-x86_64-linux.tar.gz- Works on older distros (e.g., Ubuntu 20); larger due to additional internal linking.
β οΈ If your system is musl-based (e.g., Alpine) or youβre unsure about glibc, prefer APE
ffl.com.
macOS (native)
- Apple Silicon (arm64) β
ffl-v3.9.11-aarch-darwin.tar.gz - Intel (x86_64) β
ffl-v3.9.11-x86_64-darwin.tar.gz
The archive unpacks to a single ffl binary.
π§° APE (cross-platform single file, zero external deps)
ffl.comβ Single-file build that runs natively on Linux, macOS, Windows, FreeBSD, OpenBSD 7.3, NetBSD, BIOS, and Android (Termux).fflo.comβ Alternative APE build that is exactly aligned with the open-source repo (no additional/proprietary addons).
As a result, features that require closed-source componentsβsuch as upload to server (e.g.,--upload)βare not available.
For a deeper comparison between native and APE, see the READMEβs notes.
