Built for developers, by developers

Build better digital experiences with a headless CMS that doesn't get in your way. SleekCMS gives you the flexibility, performance, and developer experience you deserve.

Built for the modern development stack

SleekCMS gives you the tools and flexibility to build with your preferred frameworks and workflows.

API-First Architecture

Build with GraphQL or REST APIs and access your content from any framework or platform.

Content Modeling Freedom

Create exactly the content structures you need with powerful relationships and validation.

Modern Development

TypeScript definitions, SDKs for popular frameworks, and CI/CD friendly workflows.

Webhooks & Automation

Connect SleekCMS to your existing tools and automate workflows between systems.

Local Development

Work locally with CLI tools and preview environments that mirror production.

Content Versioning

Track changes, compare versions, and roll back content when needed.

Simple, powerful APIs

Access your content with REST or GraphQL APIs, or use our SDKs for popular frameworks.

Fetch content with REST
// Fetch blog posts using the REST API
fetch('https://api.sleekcms.com/content/v1/blogPosts')
  .then(response => response.json())
  .then(data => {
    // Process the blog posts
    console.log(data.items);
  });
Query content with GraphQL
// Fetch blog posts using GraphQL
const query = `
  query {
    blogPostCollection {
      items {
        title
        slug
        publishDate
        excerpt
        content {
          json
        }
        featuredImage {
          url
          width
          height
          description
        }
      }
    }
  }
`;

fetch('https://api.sleekcms.com/content/v1/graphql', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ query }),
})
  .then(response => response.json())
  .then(data => console.log(data.data.blogPostCollection.items));
Using the React SDK
import { useEffect, useState } from 'react';
import { createClient } from '@sleekcms/react';

// Initialize the client
const client = createClient({
  space: 'your-space-id',
  accessToken: 'your-access-token',
});

function BlogList() {
  const [posts, setPosts] = useState([]);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    // Fetch blog posts
    client.getEntries({
      content_type: 'blogPost',
      order: '-fields.publishDate',
      limit: 10,
    })
      .then((response) => {
        setPosts(response.items);
        setLoading(false);
      })
      .catch(console.error);
  }, []);

  if (loading) return 
Loading...
; return (
{posts.map((post) => (

{post.fields.title}

{post.fields.excerpt}
