Install

Up and running in under a minute.

One native binary — no JVM at runtime, no npm toolchain. Evaluate the full UI in Docker in seconds, or run it properly under systemd.

Fastest path — evaluate in Docker

terminal
docker run -d -p 8080:8080 --cap-add NET_ADMIN \
  -e ISLANDR_ADMIN_PASSWORD=change-me \
  -v islandr:/data ghcr.io/chriscohnen/islandr:latest
# → http://localhost:8080

Boots the full console so you can click around and build a config. For real WireGuard/nftables enforcement, use one of the paths below.

Install

Pick your path.

From a throwaway dev instance to a production hub under systemd.

terminal
# Clone & run with Quarkus live coding
git clone https://github.com/chriscohnen/islandr.git
cd islandr
./gradlew quarkusDev
# → http://localhost:8080   (admin / admin in the %dev profile)
terminal
# Download pre-built binary (x86_64 or ARM64)

In production the admin password has no default — without ISLANDR_ADMIN_PASSWORD the local login stays deliberately disabled (HTTP 503). A known default in containers would be a security hole.

Production

A bare container boots the full UI so you can build a config, but enforcing nftables rules needs privileges. For production run the native binary under systemd, or attach the host socket proxy — the full install guide covers the least-privilege setup.

Get started

One binary, one command — home in under a minute.
