Carapace vs. Ghost
Category: Architectural Trade-offs
Ghost is a genuinely well-built publishing platform — a real Node application, a real database, a polished editor, and a mature newsletter/membership system on top. It's a strong choice for exactly the audience it targets: writers and publishers who want a hosted or self-hosted publishing business, not just a content site.
The actual difference
Ghost's editor and everything behind it is a live server process, whether you self-host it or pay for Ghost(Pro) to run it for you — something has to be running, patched, and paying for compute at all times. Carapace has no equivalent process at all: content is written through an AI agent into a git repository, and a visitor's request is served entirely as static files from a CDN. There's no server in the read path to keep alive, secure, or scale.
The trade Carapace is making explicitly: give up Ghost's built-in publishing-business features in exchange for a genuinely simpler, cheaper-at-scale, zero-standing-infrastructure content site.
Where Ghost is still the better choice
If what you actually want is a publishing business — built-in newsletters, paid memberships, subscriber management — Ghost has spent years building that out well, and Carapace doesn't attempt any of it, on purpose. This isn't a roadmap gap; it's a different product for a different job. If your content site's success depends on monetizing a direct reader relationship through subscriptions, Ghost is the more honest recommendation.
