Join thousands of teams already building with MasterCMS. Free to start, scales as you grow. No credit card required.
MasterCMS was born out of frustration with bloated, over-complex content management systems that slow teams down rather than empowering them.
We believe every team — from a two-person startup to a 200-person agency — deserves a CMS that's fast to set up, easy to operate, and powerful enough to never outgrow.

Every feature is designed to reduce time-to-publish. We obsess over milliseconds so your editors don't have to.
Encrypted keys, scoped API tokens, and permission-based access — security is baked in, not bolted on.
Features are shaped by real user feedback. We ship what teams actually need, not what looks good in demos.
Yes — you can create an account and publish your first website completely free. Paid plans unlock higher workspace limits, priority support, and advanced AI usage.
Absolutely. Add any domain in Settings → Domains, verify ownership via a TXT record, then point your CNAME to our servers. The whole process takes under 5 minutes.
Choose a provider (Claude, GPT-4o, Gemini) in workspace settings, describe your page, and AI generates structured HTML sections. You keep full editing control after generation.
Yes. Each workspace is isolated with its own team, pages, domains, and brand settings. You can own up to 5 workspaces and be a member of unlimited others.
Your content is stored as structured JSON and can be exported via the REST API at any time. No vendor lock-in — your data is always yours.
Your published pages remain live. You retain access to your data. Only creation of new workspaces and advanced features becomes restricted on the free tier.
