Ghost

Ghost is an open-source publishing platform for blogs, newsletters, and paid membership sites — a self-hosted alternative to Substack and Medium, backed by MySQL. IMPORTANT: after deploy you must set the url env var to your service's public URL and redeploy — Ghost builds all admin links, asset URLs, and emails from it, so left at the localhost default the /ghost admin and links break behind the proxy. Then visit /ghost to create your admin account. Content (images, themes, uploads) persists at /var/lib/ghost/content via a custom storage mount.
