Primo combines easy custom development with simple no-code editing. I get to choose which components exist and how much control to give editors.
Juri Founder at MoliriIt’s lightweight, fast, and super easy to set up. I can quickly customize my pages without dealing with complicated setups or heavy frameworks.
Vedno Web DeveloperI’ve managed a couple of custom Primo sites for years. My clients are super non-technical but onboarded in minutes and rarely reach out for help.

Frequently asked questions.
Do I need to write code?
Your agent can set up Primo and make code changes for you. Some familiarity with web projects helps you review and refine the result. Your clients update content through the visual editor.
Which AI agents can I use?
Use an agent that can edit local files and run terminal commands. Primo’s CLI works with your existing workflow, and its MCP tools give compatible agents access to field schemas and validation. The setup guide gets you started.
What can my clients edit?
Clients can update text and images, create pages from the templates you provide, and publish with the permissions you give them. You define the editable fields and available blocks. Try the editor ↗ to see how it works.
Where can I host my sites?
Choose a hosted Primo plan or run Primo on your own infrastructure. Either option gives you a browser editor for content updates. You can also build a static version to host elsewhere. Compare hosting options.
What kinds of sites use Primo?
Sites such as Amm-Am!, Leesburg Counseling, and MAAD Metal use Primo. Browse the showcase for live examples across different businesses.
Do I own my code and content?
Yes. Keep the site in your own repository and export its Svelte, YAML, and media files whenever you need them. Primo is MIT-licensed, so you can also keep running your own installation independently.
I built Primo because there was no good way to build custom sites I could hand off to my clients with confidence. Seven years later, the model still holds — it just also happens to be the shape agents want, too.
— Matthew, founder
Build with an agent.
Hand it to a human.
Start with your agent or the CLI. Build locally, then deploy an editable CMS when you’re ready.
Create a new Primo site for my client. Set up a local workspace, help me choose a marketplace starter, and open the Primo editor. Read the Primo docs at https://docs.primo.build before starting.
Paste into your AI agent.
