Build blazing fast, modern apps and websites with React

Gatsby is a modern web framework for blazing fast websites.

• Go Beyond Static Websites. Get all the benefits of static websites with none of the limitations. Gatsby sites are fully functional React apps so you can create high-quality, dynamic web apps, from blogs to e-commerce sites to user dashboards.

• Use a Modern Stack for Every Site. No matter where the data comes from, Gatsby sites are built using React and GraphQL. Build a uniform workflow for you and your team, regardless of whether the data is coming from the same backend.

• Load Data From Anywhere. Gatsby pulls in data from any data source, whether it’s Markdown files, a headless CMS like Contentful or WordPress, or a REST or GraphQL API. Use source plugins to load your data, then develop using Gatsby’s uniform GraphQL interface.

• Performance Is Baked In. Ace your performance audits by default. Gatsby automates code splitting, image optimization, inlining critical styles, lazy-loading, and prefetching resources, and more to ensure your site is fast — no manual tuning required.

• Host at Scale for Pennies. Gatsby sites don’t require servers so you can host your entire site on a CDN for a fraction of the cost of a server-rendered site. Many Gatsby sites can be hosted entirely free on services like GitHub Pages and Netlify.

🚀 Get Up and Running in 5 Minutes

You can get a new Gatsby site up and running on your local dev environment in 5 minutes with these four steps:

1. Install the Gatsby CLI.

   npm install -g gatsby-cli
   
   

2. Create a Gatsby site from a Gatsby starter.

   Get your Gatsby blog set up in a single command:

   # create a new Gatsby site using the default starter
   gatsby new my-blazing-fast-site
   

3. Start the site in develop mode.

   Next, move into your new site’s directory and start it up:

   cd my-blazing-fast-site/
   gatsby develop
   

4. Open the source code and start editing!

   Your site is now running at http://localhost:8000. Open the my-blazing-fast-site directory in your code editor of choice and edit src/pages/index.js. Save your changes, and the browser will update in real time!

At this point, you’ve got a fully functional Gatsby website. For additional information on how you can customize your Gatsby site, see our plugins and the official tutorial.

🎓 Learning Gatsby

Full documentation for Gatsby lives on the website.

• For most developers, we recommend starting with our in-depth tutorial for creating a site with Gatsby. It starts with zero assumptions about your level of ability and walks through every step of the process.

• To dive straight into code samples head to our documentation. In particular, check out the “Guides”, “API Reference”, and “Advanced Tutorials” sections in the sidebar.

We welcome suggestions for improving our docs. See the “how to contribute” documentation for more details.
