Local-first
No account, no server, no tracking. Just your browser.

faq
still curious? ask on Discord.
Yes — everything is stored in your browser's localStorage. Nothing is ever sent to a server. Only you can see it.
No account needed. Open the app and start using it.
Yes. Paste in your Pluralkit token (use pk;token in a server with the Discord bot), and pull in your alters.
Clearing cookies/localStorage will delete your data. Use Settings → Export regularly to keep a JSON backup you can re-import.
Completely free and open source. You can donate to support development if you'd like, but there's no pressure and nothing is paywalled.
