Description

Curious how much a new npm package will add to your project's size? Bundlephobia gives you a clear picture of the footprint for any JavaScript package. You can quickly check the size and understand its potential impact on your site's performance, helping you make smarter decisions about your dependencies. This means you can optimize your frontend bundles effectively, leading to faster load times for your users and a smoother experience overall. Knowing the real cost of each package lets you keep your projects lean and efficient. • See individual package sizes • Understand the impact on your total bundle • Make informed dependency choices • Works even when you're offline You can open Bundlephobia right in your browser and then add it to your home screen with a single tap. From that point on, it opens in its own window, just like a native app. It also gets silent updates in the background and supports push notifications, offering the same great experience as the native version without needing a store account or a separate download.
