Cactal is an AI website platform that designs, builds, and runs production websites for freelancers, agencies, and the businesses they serve.
We're building the best website platform in the world. Cactal lets people decide what to build while AI agents handle the website work.
What Cactal does
AI design and build
You describe what you want in plain language and an AI agent builds, edits, and publishes the site. Pages look like a design studio made them, quality-checked before they ever go live, with none of the generic AI look.
Updates in plain language
Describe the change, “add a services page, lead with the new offer”, and it ships. You or your agent, no builder to learn.
A CMS your team can edit
Copy, posts, and pages live in a built-in CMS. Your team updates them directly, no developer on call.
Hosting and domains
Fast, managed, CDN-served hosting is part of the platform. No plugins to update, no servers to maintain. Every site gets a free Cactal domain, and you can connect your own when it's ready to go live.
SEO handled
Sitemaps, redirects, metadata, and canonicals are taken care of on every page, nothing to configure or forget.
Analytics you understand
First-party analytics that answer the questions you actually have: who came, from where, and what they did. Hand clients the numbers that go in their monthly report.
Forms
Contact and lead forms work without extra tools. Submissions arrive in your Cactal dashboard and by email.
Versioned publishing
Every change renders as a draft on a preview URL first, so you see exactly what will ship before anyone else does. Every publish is recorded as a version in your site's history, and you can restore any previous version in one click.
What makes Cactal different
For decades, making a website meant humans learning complicated tools, coordinating specialists, and iterating through slow cycles. Now AI does the work itself, not just the design: people bring the intent, taste, and approval, and agents build, revise, publish, and run sites over time.
Most platforms bolt AI onto an editor built for human hands. Cactal is designed agent-first from the ground up, every capability, from the CMS to publishing to analytics, can be operated by an agent as cleanly as by a person.
Quality first
The bar is output worth shipping to a paying client. If the websites are not exceptional, nothing else about the platform matters. Every build is validated before it serves, so broken output never reaches your visitors.
Safe to change
Agents get real power, so safety is built in: versioned changes, quality gates before anything goes live, and rollback when you need it. Your site is never one bad edit from broken.
Code you own
Your sites are real React source code rather than rows in a page format only we can read, so you can take that code and run it anywhere. There is no export to buy and no conversion to do.
Priced by live sites, not seats
Building, previewing, publishing, and serving on a Cactal domain are unlimited and free on every plan. Pro covers one website on your own domain and every one after that is $20/mo, with unlimited members included, so an agency taking on a fifth client pays exactly what it paid for the second.
Open interfaces
The full API, SDK, and MCP server ship on every plan, including Free. We don't paywall the platform's interfaces. Your agent gets the same API our own dashboard is built on, from the first day.

The team behind Cactal
Mike Tromba, founder
Cactal is built by Mike Tromba, the maker of UX Canvas, an AI design agent, "Cursor for product design," used by more than 10,000 people. It turned plain conversation into interface designs good enough that people paid for them, and kept coming back.
Cactal is based in Austin, Texas.
Where Cactal came from
UX Canvas's best, most-retained customers were agencies building marketing websites for their clients. Many had replaced their human designers with it entirely. But they kept hitting the same wall: a great design still had to be implemented, and on WordPress-era stacks and page builders that meant staffing developers, waiting on builds, and hoping the live site matched what they had promised the client.
The lesson was clear. With modern AI, implementation is a solved problem, the missing piece was a complete, agent-native platform that takes a great idea all the way to a live, high-performance, SEO-ready, CMS-backed website, without stitching tools together. So we built it. That platform is Cactal.

Frequently asked questions
Do I need to know how to code?
No. You describe what you want in plain language and an AI agent builds, edits, and publishes the site. Full code access is there when you want it.
Can I use Cactal without paying?
Yes, and not as a trial. The Free plan has no time limit and asks for no card. You can build unlimited websites, publish them, and keep them serving on a Cactal domain for as long as you like.
Do I have to bring my own AI agent?
No. Cactal's agent is built in, and every plan includes AI credits: 100 a month on Free and 1,000 on Pro. If you'd rather use Claude, Cursor, or your own agent, connect it over MCP on any plan.
What does a client site cost me?
Each client site on its own domain is $20 a month. Building, previewing, and publishing on Cactal domains is free and unlimited, so pitching costs nothing and the meter starts when the client goes live on their own domain.
Can clients and team members have their own access?
Yes. Invite unlimited members and assign granular roles, content-only or full-site, scoped per client.
What happens if I cancel?
Cancelling drops you back to Free: your sites, source code, and content are all still there, still yours, and still served on their Cactal domains.
