Build blazing fast, modern apps and websites with React

Gatsby

The future of web development is here.

Gatsby is a free and open source framework based on React that helps developers build blazing fast websites and apps.
It combines the control and scalability of dynamically rendered sites with the speed of static-site generation, creating a whole new web of possibilities.

Gatsby helps professional developers efficiently create maintainable, highly-performant, content-rich websites.

• 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.

• 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.

• Choose your Rendering Options. You can choose alternative rendering options, namely Deferred Static Generation (DSG) and Server-Side Rendering (SSR), in addition to Static Site Generation (SSG) — on a per-page basis. This type of granular control allows you to optimize for performance and productivity without sacrificing one for the other.

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

• 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.

• 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 Gatsby Cloud and other similar services.

• Use Gatsby's Centralized Data Layer Everywhere. With Gatsby's Valhalla Content Hub you can bring Gatsby's data layer to any project. Making it accessible via a unified GraphQL API for building content sites, eCommerce platforms, and both native and web applications.

🚀 Ship your first Gatsby site in 5 Minutes

Click the link below to quickly try the workflow of developing, building, and deploying websites with Gatsby and Gatsby Cloud.

At the end of this process, you'll have

1. a site working on Gatsby Cloud
2. a new repository that is linked to that new site
3. as you push changes to your new repository, Gatsby Cloud will automatically rebuild and redeploy your site!

💻 Get started with Gatsby locally 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. Initialize a new project.

   npm init gatsby

   Give it the name "My Gatsby Site".

2. Start the site in develop mode.

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

   cd my-gatsby-site/
   npm run develop

3. Open the source code and start editing!

   Your site is now running at http://localhost:8000. Open the my-gatsby-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.
