We got tired of bad CMS options
Every CMS we tried was either bloated, locked-down, or stuck in 2015. So we built something we'd actually want to use.
The Short Version
We wanted a CMS that lets you build pages visually, connect your own domain, and talk to AI to get things done - without paying enterprise prices or fighting a WordPress dashboard. Cmssy is that. It's multi-tenant, so one account handles all your sites. It's block-based, so you assemble pages instead of designing from scratch. And it has an MCP server, so Claude can build and manage your site through conversation.
What We Care About
AI That Does Real Work
Not autocomplete. Not suggestions in a sidebar. Claude talks to Cmssy directly — creating pages, editing blocks, publishing changes. That's the bar.
Developer-Friendly
TypeScript everywhere. GraphQL API. Clean monorepo. We build for people who look at source code and want to understand it.
Build in the Open
Public roadmap. Docs you can actually follow. We'd rather ship something good and iterate than hide behind a waitlist.
Security Is Not Optional
JWT auth, workspace isolation, role-based access. Every workspace is a locked room. We don't cut corners here.
Speed Matters
Next.js 15, React 19, lazy-loaded blocks, content hashing. Pages load fast because we spent the time making them fast.
Users Shape the Product
Feature requests go on the roadmap. Bug reports get fixed. We don't have a 200-person team deciding what matters — our users do.
