This is an excellent library! I only wish it had react-native support.

I've worked on a few prototype react directed acyclical diagram libraries. jsplumb-react, react-yad, and recently @lincle.

@lincle is my most recent and first attempt at supporting react-native. I tried leveraging existing interactive libraries. I was also inspired by react-flow's minimap. It is still a prototype and needs documentation but works well. I'm realizing now the demo isn't working but the demo source should hopefully give an example of how to use it.

With expo DOM components it’s easy to just use this library and expo will wrap it in a webview. Then you can easily integrate it into a RN app.

It's a lovely library :) I'm using it in my work on general interfaces for symbolic execution debugging.

This is cool. Is there web component library/resources for something equivalent?

Great library. Just memo your custom nodes properly - edge re-renders cascade faster than you'd expect.

I'm a long-time SvelteFlow user and it has never disappointed so far :).

Lots of updates this year to reach parity with React Flow.

This is a well-done library that’s fun to work with. I put together a proof of concept org chart generator[0] with it a while back when working on another project. Very easy to use and well-documented.

Does React Flow still advertise itself unless you pay the developers at least $169/month?

You can programmatically remove the watermark, either via a flag or by changing the source code.

> [1] No, you can do whatever you want with it since it’s MIT

But if you use it in a commercial project, they'll likely shame you if you don't pay - like what happened to OpenAI with Agent Builder:

> [2] Hey @OpenAI :) We just saw that you are using our open source library React Flow We offer startup discount codes :) Let us know if you are interested

Personally, I’d prefer them to use a dual license, but I understand that it would likely create unnecessary hurdles for devs who just want to try out the library.

They explained their reasoning here: https://xyflow.com/blog/asking-for-money-for-open-source

Hah, this pops up right after I note how it's eating good with all the AI tools that use it. Deservedly so, if you're creating node based interfaces there's no reason to hand roll with D3.
