Sitessa for

Every client site. Under your brand.

Give each client their own site, model and logins. Keep your agency's name and colors on the CMS, and let your AI draft the busywork.

How it works

Six steps, on the real app.

From the first client site to an AI that writes in that client's voice. The ring marks what to click.

Step 1 of 6

Every client in one suite.

Each client gets a site with its own content model, media, people and MCP endpoint. Switch between them from one sidebar.

New client sites

Start from a template.

Four templates, or the structure of a site you already built. Everything stays editable afterwards.

A full product site: features, docs, pricing, blog and changelog.

White label

Your name on the door.

Set your agency's name, logo, icon and colors once. Each client site can carry its own logo and colors on top.

One brand for the CMS.

Your agency’s name, logo, icon and two colors. Text contrast is kept readable for you.

Members and roles

Clients see only their site.

People join one site with one role. Start with Admin, Editor and Viewer, or make your own.

AI per client

Each client's voice, kept.

Every site has its own house rules and banned words, and its own MCP URL. An AI working for one client can't touch another.

Example rules. Each site writes its own in Settings › AI guidelines.

- Plain, friendly and specific.- Sentence case for headings. No em dashes.- No invented stats, ratings or customer names.- Save everything as a draft.
