BlancoKit: Discord toolkit

BlancoKit is a free Discord toolkit in your browser. Start with the Banner Color Matcher, then use lookup tools, bot builders, embed and slash-command JSON helpers, and reference pages for boost perks and markdown.

Most tools run entirely in your browser. Public user lookups and invite resolution are proxied server-side. Optional gateway shard fetch on the Shard Calculator sends your bot token only to discord.com, never to BlancoKit.

How do I match a Discord profile color to a banner color?

Open Banner Color Matcher, enter your profile theme hex, and the tool applies an approximate 40% blend toward black or white. Discord does not publish the exact formula. Live preview and PNG export included.

Can I look up a Discord user by ID?

Yes, for public data only: avatar, banner image, accent color, badges, clan tag, and member since. Nitro theme picker colors, about me, pronouns, and connections are not exposed by the bot API.

Does live presence work for everyone?

Only for users who opted in via Lanyard. The presence tool fetches data through a server proxy and shows a disclaimer when a user is not on Lanyard.

Is my bot token sent to BlancoKit?

No. The Shard Calculator gateway fetch runs in your browser and contacts discord.com directly. BlancoKit never receives or stores bot tokens. Public lookups use a server proxy with no user token required.
