Looks promising and quite handy for my project

I joined a project last year which uses Konva inside an Angular application. It was my first time doing any kind of canvas programming, but the ergonomics of konva can be picked up quite rapidly and I've been enjoying quite a lot.
We're working on performance-sensitive project, so one lesson we learned is that all shapes listen to all mouse events by default. We didn't even have lots of shapes, but this was enough to have a noticeable performance hit due to all the event handlers being registered. We pivoted to an opt-in approach instead and that fixed most of our problems.

The site and docs for Konva are conspiciously pleasant and well fleshed out. The "price" link jumpscare is also something I haven't yet seen.

What is the purpose? React for Canvas tag?

For folks who have used this, why would you choose this instead of SVG inside React, Svelte, etc?

Don't know about the library but the spreadsheet project built on top is impressive https://www.rowsncolumns.app/

Is this a community-driven project, or is there a company behind the project?

I used this for a project a few years ago. It's quite intuitive and made developing a workflow/graph editor a relative breeze.

I haven't tried Konva. But have been using fabric js for an image editor I've been working on. I guess they both do a good job.

Is this the successor library for KineticJS and ConcreteJS?
Kinetic was amazing back in it's day, but lacked SVG export. I wonder if that's built-in now

How does this compare to tldraw in terms of featureset / target market?

I've used PixiJS and react-pixi-fiber to write a declarative 2D WebGL renderer in React with excellent results. PixiJS also has a Canvas2D fallback when WebGL isn't available. I wonder how this compares.

Reminds me of p5.js – I still fall back to it to do some quick graphics.

I evaluated this vs pixi and native canvas API. In the end I decided to use native API.
Konva didn't have enough performance for my use case and pixi webgl has a limit on the number of canvases on the screen at the same time
The native API is easy to use and well documented. It also performs well enough to animate charts at 60fps on modern hw for my use case. I also like that there are no libraries to update

I made a jigsaw puzzle (featured in the Konva's home page) years ago. Recently did a full conversion to ReactKonva using Claude and it's a breeze.

Pricing is unbelievable

I discovered Konva just this week and it has been extremely helpful for jumpstarting my latest project. I've been impressed with the docs and the examples and the ergonomics of the api giving me an unusual amount of "it just works" moments.
