Why We Built Cortex on Ghost CMS

The Problem with Existing Platforms

We evaluated every publishing platform before building Cortex. WordPress was too bloated — 60+ plugins just to match Ghost is built-in features. Substack was too limited — no custom design, no SEO control, no ownership of the reader relationship. Medium was a dead end — algorithmic distribution that you cannot control.

Why Ghost Won

Ghost is an open-source publishing platform built specifically for professional publishers. It includes everything we needed out of the box:

• Native membership and subscriptions — Stripe integration with zero revenue share
• Email newsletters — send posts as emails to segments of your audience
• Full theme control — Handlebars templates, custom CSS, total design freedom
• SEO-first architecture — clean URLs, structured data, fast page loads
• Content API — headless capability when you need it

The Developer Experience

Ghost themes are refreshingly simple. Handlebars templates, CSS, a bit of JavaScript. No build tools required. No framework lock-in. The theme system is powerful enough for complex layouts but simple enough that a single developer can build a production theme in a week.

The Admin API lets us automate content operations, and the Content API enables custom integrations. It is the best of both worlds: a managed CMS with escape hatches when you need them.

The Economics

Self-hosted Ghost costs $5-10/month on a VPS. Ghost Pro starts at $9/month. Compare that to WordPress hosting plus premium plugins, and Ghost is cheaper for a more capable platform. Stripe handles payments at standard rates — Ghost takes zero commission on your membership revenue.
