That does not mean the project is deprecated, though...
pk-webs-beta, the svelte rewrite of this project, now lives on as the official PluralKit dashboard! Feel free to make contributions to the official PluralKit repository. All links to https://pk-webs.spectralitree.com should be redirecting to https://dash.pluralkit.me instead.
A web interface for pluralkit. Check it out at https://spectralitree.github.io/pk-webs/
This is a work in progress. The code is super messy, many features are not added yet, and I cannot guarantee that this is completely bugless. Feel free to open an issue if you notice anything wrong.
