Open Iframe Resizer

About the project

Why another lib ?

The existing Iframe Resizer library is solid, but it’s no longer usable for free in commercial projects. I wanted to offer a modern alternative: focused on simplicity and efficiency.

  • The library creates only one ResizeObserver to track the iframes, and does not rely on MutationObserver or IntersectionObserver, making it very lightweight.
  • I try to keep the API as close as possible to the original library to ease migration, though some features will not be implemented the same way.
  • Unified packaging: For simplicity, both the child and parent packages are included in the same module.
