koel/franken

Standalone-binary distribution of Koel, powered by FrankenPHP — a single download that includes the Caddy webserver, the PHP runtime, and Koel itself.

No Composer, no Node, no system PHP needed on the host.

Usage

Download the archive for your platform from the Releases page, extract it, and run:

tar -xzf koel-franken-v9.3.3-linux-x86_64.tar.gz
cd koel-franken-v9.3.3-linux-x86_64
./koel php-server --listen :8000

On first run, Koel sets up $HOME/.koel/, generates an app key, and creates a fresh SQLite database. Then it starts serving on the chosen port.

For Artisan commands, use the ./artisan shortcut:

./artisan koel:sync
./artisan tinker

Upgrading

To upgrade to a newer release:

1. Download the new archive from the Releases page.
2. Extract it over the existing directory.
3. Restart the server.

Your data in $HOME/.koel/ — settings, database, uploaded images, search indexes — is preserved across upgrades.

What lives where

Everything writable lives under $HOME/.koel/:

Path	What
$HOME/.koel/.env	Environment file (Koel's config)
$HOME/.koel/db.sqlite	SQLite database
$HOME/.koel/storage/	Laravel storage path (logs, sessions, cache, uploaded images)
$HOME/.koel/storage/app/artifacts/	Transcodes, downloaded podcast episodes, temp downloads
$HOME/.koel/php.d/koel.ini	PHP-INI overrides (512M uploads, longer timeouts)

See the Standalone Binary guide for customization, systemd setup, and running behind a reverse proxy.

Local development

To build for the current host:

./build.sh

To build a specific Koel/FrankenPHP/platform combination:

KOEL_VERSION=v9.3.3 \
FRANKENPHP_VERSION=v1.12.2 \
PLATFORM=linux-aarch64 \
  ./build.sh

The result lands in build/koel-franken-<koel-version>-<platform>/.

Supported platforms: mac-arm64, mac-x86_64, linux-x86_64, linux-aarch64.
