I can recommend to implement such tools platform independently so that they also run in browsers.

Trying out a web tool is much less easier and safer than installing and running a tool locally that could do anything on my computer. If the tool looks and feels good on the web, it is much more likely that someone will install it locally.

Thanks for the feedback!

I couldn't agree more. I actually deliberately used the XML DOM(Parser) API for SVG so that it could also run in the browser. I just haven't gotten around to creating a Web bundle yet, but I'll be adding that really soon.

For what it's worth, there's now a basic Web version: https://swirly.timdp.now.sh/

That looks nice! I would recommend you to host in on gh-pages though so that it still works even if you decide to take down your website.
