SleekCMS review: AI website builder with forms, online booking, SEO and hosting for small businesses and agencies. Free plan, paid plans from $20/month.
Researched and fact-checked by Bartu Cavusoglu · Updated October 26, 2026
SleekCMS is a website platform that combines an AI website builder, a static site generator, a headless CMS, lead forms, online booking, SEO tools, and hosting with domains. A small business owner describes the business and receives a first draft of a site with a contact form, booking calendar and search metadata already in place.
Beyond the no-code builder, SleekCMS offers a REST API, a TypeScript-friendly SDK, and multi-site tools for agencies. Its About page says it was built because headless and no-code should not be opposites. The company is headquartered in San Jose, California, with engineering in Bangalore, India.
Content is modeled as pages, entries and blocks, and a cloud static site generator renders it with EJS views that have the whole content graph in scope. There is no repository, build pipeline or framework to maintain. Sites publish to a global CDN with automatic HTTPS from the first save.
You can build with the in-app AI assistant or bring your own agent, such as Claude Code, Codex or Cursor, through SleekCMS Sync, which exposes the site as local files and deploys on every save. Versioned publishes allow rollback, and a live preview works without a separate preview app.
Forms capture contact, quote, booking-request and newsletter submissions, store them in a searchable dashboard, and email each one. Booking calendars let customers pick a slot, then send confirmations, reminders and calendar invites and handle cancellations and reschedules, so no separate scheduling subscription is needed.
The AI SEO assistant audits every page, benchmarks a competitor URL, and rewrites titles, meta descriptions, structured data, Open Graph tags and sitemaps across the site. For developers, the platform adds a one-fetch REST API, the @sleekcms/client SDK, environments, and triggers or webhooks.
