See all available APIs, components, hooks, & utilities.


Welcome, developers! Our docs cover guides, examples, references, and more to help you build your next Notion apps or bring your ordinary products & tools into Notion to streamline your tasks and/or serve 30+ millions of users.

The nbundle Platform consists of three parts:

  • API: This allows developers to build rich Notion apps with React, Node.js, and TypeScript or JavaScript. The docs explain how to use the API to build top-notch Notion-like experiences.

  • Developer Portal: This lets developers publish & manage their apps for all Notion & nbundle users. You'll learn how to publish & manage your apps.

  • App Store: This lets Notion users discover, install, use, & manage their apps.

Key features

Here are a few points that make our ecosystem special:

  • Powerful and familiar tooling: Apps are built with TypeScript and/or JavaScript, React, and Node.js. Leverage npm's ecosystem to quickly build what you imagine.

  • No-brainer to build UI: You concentrate on the logic, we push the pixels. Use our built-in UI components to be consistent with Notion and all apps.

  • Developer experience front and foremost: A strongly-typed API, hot-reloading, sourcemap-enabled, and modern tooling that makes it a blast to work with.

  • Easy to start, flexible to scale: Start a new project with a single command, add a static UI or use React to go wild. Anything goes.

  • No DOM hacking: Using the SDK means no more lost time hacking Notion's DOM, no more late nights when Noton slightly changes their DOM.

  • Zero maintenance: The SDK is designed with a changing Notion in mind. All APIs are handled by the nbundle App Store, which is always up-to-date with Notion. You do literally nothing to keep your apps up-to-date.

  • Get users from our marketplace: The nbundle App Store lives inside Notion, where 30 million users spend hours every day. Apps get more visits & users by just being in our App Store.


The nbundle Platform is free for every developer and most apps:

  • Free: if your app is making less than $10,000/year.

  • Custom plan: if your app is making more than $10,000/year.
