Yours from end to endYour AI agent. Your data.
Your AI agent. Your data.
Your server.
Choose the AI you work with. Keep your website files and CMS records on hosting you control. You decide what changes and when it goes live.
Your data
Your pages, images, posts, form submissions and booking records live on your hosting. Keep access to your files and database, with backups before every publish.
Your server
Install Nexstarc CMS on compatible PHP hosting, under your own domain. Publish plain HTML pages and keep the freedom to move your website to another host.
Your website is self-hosted. Content you share with your connected AI agent is also processed by that AI provider under its own terms and settings.
How it works
From install to your first page in four steps
No developer needed to get going. If you can upload a folder and copy a command, you can run it.
- 1Install your server
- 2Sign up
- 3Connect your AI
- 4Work with your AI agent
01
Install your server
Upload one folder to your hosting and open the setup page. It checks your server, connects the database and prepares the site folder for you.
- Works on ordinary PHP hosting (MySQL, MariaDB or SQLite)
- A guided four-step installer with a live “Test connection”
- Your site, your files, your hosting. No lock-in.
02
Sign up
Create your owner account in the last step of the installer. That is your login to the admin where you approve everything.
- Add editors and viewers later, each with the right level of access
- Strong passwords and sign-in protection built in
- Every action is recorded in an activity log
03
Connect your AI
Create a connection and paste one command into Claude, Codex or Cursor. Your AI can now see the site and stage changes. You decide whether it may ever publish on its own. By default it cannot.
- Ready-made commands for each AI app
- Revoke or replace a connection in one click
- One connection per person or agent, so you always know who did what
04
Work with your AI agent
Describe what you want in plain words. The agent writes the pages, checks speed and SEO, and sends you a draft. You preview it, approve it, and it goes live. Ask again whenever you want a change.
- “Build a 5-page site for my clinic with online booking”
- “Add a blog post about whitening and link it from the home page”
- “Connect the contact form so messages reach my inbox”
Why it is different
AI does the work. You keep the keys.
Most tools that let AI touch your website either cannot be trusted to change it or cannot be stopped from breaking it. Nexstarc CMS was designed around a simple rule: the AI proposes, a person approves.
You stay in control
Every change is a draft first. You see exactly what changed, preview it, then approve. A restore point is saved before every publish, so you can roll back.
Fast by default
Visitors get plain HTML files, with no database or PHP on page views. The built-in audit scores every page for speed and SEO before you publish.
Yours to own
It runs on your hosting with your domain and your files. Nothing is trapped in a platform, and your AI is the one you already use.

Work with your AI agent
Just say what you want
Your AI picks the right tools, builds a draft, checks it, and sends it to you. You read a clear summary, preview the page, and decide.
Examples your AI can handle today: build a site, edit pages, add a blog post, set up booking, connect forms, import an existing site, check SEO and AI visibility, and restore an earlier version.
YouBuild a 5-page site for Maple Dental in Brooklyn. Calm teal, online booking and a contact form.
Your AIDone. I built 5 pages, set up booking with three services, and connected the contact form. All pages score 100 on the audit. Preview is ready.
YouAdd a blog post about whitening costs.
Your AIDrafted “Teeth whitening: what it costs and what to expect” in the Whitening category. Ready for your review.
YouCheck the services page for SEO and AI visibility.
Your AIReviewed it. The title and description are fine, but there are no question-style headings and no structured data. I drafted fixes and kept the design the same. Ready for your review.
Be found
Be found by search engines and AI assistants
Nexstarc CMS measures the facts about every page. Your AI reads them, tells you what to fix, and stages the fixes as a draft you approve.
- Facts, not scores.For every page: title and description, headings, question headings with their answers, structured data, links, sources, and the text a crawler can read without JavaScript.
- AI crawler access at a glance.See which crawlers your robots.txt allows, including GPTBot, ClaudeBot, PerplexityBot, Google-Extended and Googlebot, plus llms.txt, your sitemap and duplicate titles.
- A ready prompt for every page.Press Copy prompt and paste it into your AI. It reads the facts, explains what is weak, and drafts the fixes without touching your design.
- See it before it ships.Previews show how a page can look as a Google result on desktop and mobile, and as a Facebook, LinkedIn or X card.
An honest note. It reports facts and suggests fixes. It cannot promise rankings, or that an AI assistant will mention your business. Nothing changes on your site until you approve it.
Answer-engine facts for one page: the opening paragraph, and each question heading with the answer written right below it.
Preview: the same page as a Google result and as a share card.

Good to know
Runs on ordinary hosting
Most shared hosting plans with cPanel are enough. We test on real hosts, and the installer checks yours before it installs anything.

With the usual extensions. The installer lists what it finds. - MySQL, MariaDB or SQLite
Create a database in your hosting panel, or use SQLite with no setup. - Apache-style hosting with .htaccess
Standard on cPanel, LiteSpeed and most shared hosts. - Private beta
We are onboarding a small number of agencies and businesses, and we help you set up.
Questions
Frequently asked questions
What is Nexstarc CMS?
It is a content management system built so an AI agent can operate it. Your agent builds and edits the site as plain HTML files. You preview every change and approve it before it goes live.
Do I need technical skills?
No developer is needed to get started. You upload one folder, run a guided installer, then paste one command into your AI app. After that you work in plain words. Our studio can also install and manage it for you.
Which AI can I use?
Any AI app that supports the open MCP standard, such as Claude, Codex and Cursor. You connect it once, and you can use more than one.
Can the AI publish without my approval?
Not unless you allow it. By default the AI can only stage drafts, and you approve each change in the admin. Publishing rights are a switch on each AI connection, and every publish is backed up.
Where does my website live?
On your own hosting and domain. Nexstarc CMS installs in a folder next to your site and publishes static pages into it. If you prefer, we can host and set it up for you.
Can I bring my existing website?
Yes. Upload the files or a ZIP and Nexstarc CMS shows a report first. It then stages the site for your review without changing the design. Only file names that cannot be published are adjusted, and links to them are updated.
How fast will my site be?
Sites built for it are plain HTML with no database on page views, and each page is audited for speed and SEO before you publish. Imported sites keep their original design, so their scores depend on how they were built. Real results also depend on your hosting and content.
Will Google, ChatGPT and other AI assistants find my site?
No tool can honestly promise rankings or mentions. Nexstarc CMS shows you the facts those systems read: titles, descriptions, headings, structured data, which AI crawlers your robots.txt allows, your sitemap and llms.txt. Your AI explains what is weak and drafts fixes, and you approve them. Pages are plain, fast HTML, which also helps crawlers read them.
Is it safe?
The AI can only write web files into a draft. It cannot write server code or publish unless you allow it. Changes are backed up, roles limit who can do what, and form and comment input is treated as untrusted. As with any software, keep your hosting updated.
What can it not do yet?
Online shops with checkout, member logins and custom web apps are not supported, and sites exported from frameworks such as Next.js need to be exported as plain HTML first.
Which hosting do I need?
Ordinary web hosting is enough: PHP 8.1 or newer, MySQL, MariaDB or SQLite, and Apache-style hosting with .htaccess, as on cPanel and LiteSpeed. The installer checks your server before it installs anything.
