Install Kefal on a Linux server

Run this one-liner on any Linux (amd64) server. The agent will prompt for an API key on first run — generate one in Settings → API Keys first.

curl -L -o kefal-agent https://kefal.dev/download/kefal-agent-linux-amd64
chmod +x kefal-agent
sudo ./kefal-agent

⚠️ This key is shown once. After you close this dialog the plaintext is gone — only its hash stays on our servers.
