Our verdict on SleekCMS
SleekCMS combines a hosted website builder with a headless CMS for developers, freelancers, small businesses, and web agencies. It supports structured content models for pages, entries, and blocks, alongside AI-assisted creation and editing. Agencies can publish static sites, use CDN hosting, manage forms and leads, add online booking, handle SEO metadata, and give clients controlled editing access. The platform is available through web, Windows, macOS, Linux, and API workflows.
Its strongest fit is for teams that want development flexibility without giving up client-facing editing tools. The headless REST API includes JavaScript and TypeScript clients, while SleekCMS Sync supports local development. Integrations with React, Next.js, Astro, Nuxt, 11ty, GitHub Actions, Netlify, Vercel, Claude Code, Cursor, and Codex support modern agency workflows. Site cloning and reusable templates can also help standardize delivery across projects, while the organization dashboard brings multiple sites into one management layer.
The published plans show a useful free starting point, including the site builder, headless API, AI writing assistant, forms, lead management, ZIP download, and community support. Plus costs $20 per month or $200 per year and adds basic roles, removal of the SleekCMS badge, Netlify and Vercel deployment, version revert, preview, and email support. Business costs $100 per month or $1,000 per year and adds advanced permissions, CRM webhooks, priority support, and partner program eligibility. Enterprise adds custom contracts, volume pricing, SSO/SAML, dedicated SLAs, white-labeling, and unlimited sites. SleekCMS suits technical agencies building structured, repeatable sites; agencies needing advanced controls across many projects should evaluate the higher tiers.
