+        ## Apply to be included as a recommended React framework
+
+        _This form is for framework authors to apply to be included as a recommended [React framework](https://react.dev/learn/start-a-new-react-project). If you are not a framework author, please contact the authors before submitting._
+        
+        Our goal when recommending a framework is to start developers with a React project that solves common problems like code splitting, data fetching, routing, and HTML generation without any extra work later. We believe this will allow users to get started quickly with React, and scale their app to production.
+        
+        While we understand that many frameworks may want to be featured, this page is not a place to advertise every possible React framework or all frameworks that you can add React to. There are many great frameworks that offer support for React that are not listed in our guides. The frameworks we recommend have invested significantly in the React ecosystem, and collaborated with the React team to be compatible with our [full-stack React architecture vision](https://react.dev/learn/start-a-new-react-project#which-features-make-up-the-react-teams-full-stack-architecture-vision).
+        
+        To be included, frameworks must meet the following criteria:
+        
+        - **Free & open-source**: must be open source and free to use.
+        - **Well maintained**. must be actively maintained, providing bug fixes and improvements.
+        - **Active community**: must have a sufficiently large and active community to support users.
+        - **Clear onboarding**: must have clear install steps to install the React version of the framework.
+        - **Ecosystem compatibility**: must support using the full range of libraries and tools in the React ecosystem.
+        - **Self-hosting option**: must support an option to self-host applications without losing access to features.
+        - **Developer experience**. must allow developers to be productive by supporting features like Fast Refresh.
+        - **User experience**. must provide built-in support for common problems like routing and data-fetching.
+        - **Compatible with our future vision for React**. React evolves over time, and frameworks that do not align with React’s direction risk isolating their users from the main React ecosystem over time. To be included on this page we must feel confident that the framework is setting its users up for success with React over time.
+        
+        Please note, we have reviewed most of the popular frameworks available today, so it is unlikely we have not considered your framework already. But if you think we missed something, please complete the application below.
