Summary

SleekCMS combines a headless CMS, site builder, and publishing layer for structured content and static websites. Users can generate a website from a prompt, then edit it with a built-in assistant or external coding agents. Its content model uses Pages, Entries, and reusable Blocks with typed fields and explicit references. A REST API and TypeScript client return the content graph in one request, and named framework integrations include Next.js, Astro, Nuxt, and 11ty. Forms can collect leads without a backend; date-time fields can support appointment booking with confirmation emails and calendar invites. Form webhooks can send submissions to HubSpot, Salesforce, Mailchimp, or any HTTP endpoint. Published sites are static pages served on a global CDN, with automatic SSL and custom domains included on every plan. Each publish creates an immutable version that can be previewed, tagged, or rolled back. The free plan is 0.00 USD per free and includes 2 sites and community support. Plus costs 20.00 USD per month, billed monthly; an annual option is $17 per month, billed as $200 per year.
