WordPress, EmDash, Astro, or a mix.

We still believe in WordPress. We also believe the way sites get made has changed. Every site has two layers, where content is edited and how pages render, and we build and run every combination that makes sense.

How they fit

Two layers, four setups

EmDash is a CMS, like WordPress. Astro renders the pages, like a WordPress theme. Mix them the way the site needs.

Our thesis

Why we build on WordPress, EmDash and Astro

  1. 1
    WordPress is not going anywhere. It still runs more of the web than anything else, and it is the best editorial backend there is. We maintain thousands of WordPress sites and will keep doing it.
  2. 2
    How sites get made has changed. People now start in a chat window, not a theme directory. Simple sites want to be fast, static and nearly maintenance-free, and Astro is the best way we know to build them.
  3. 3
    The CMS is being rebuilt for that world. EmDash is an open-source, TypeScript CMS for Astro: content types defined in the admin, plugins that run in their own sandbox, and an MCP server on every site so your team and your AI agents edit the same content.
  4. 4
    WordPress is moving there too. WordPress's co-founder calls Spacefast, a Seahawk partner, the future of WordPress and AI. It runs on wp.cloud, Automattic's WordPress infrastructure, for a real database, auth, uploads, email and spam protection behind modern, AI-built sites.
  5. 5
    So we serve every use case. WordPress where it is the right tool, EmDash and Astro for new sites that want a modern CMS, Astro alone where nothing needs editing, and WordPress + Astro where you need both. One partner, whichever way your site goes.
