What is Weight on planets?

Weight on planets is one of 590+ free widgets on PlanckUi. Your weight elsewhere in the solar system. Small interactive utilities give visitors a reason to stay, return and bookmark you.

Perfect for sidebars, tool pages and resource collections.

Everything is rendered in an isolated shadow DOM, so it can never conflict with your site's own styles — and at a few kilobytes, it won't move your page speed.

Everything included

  • Your weight elsewhere in the solar system.
  • Free forever — no watermark, no usage limits, no "upgrade to remove"
  • Customize everything: colors, fonts, corner radius, shadows, dark mode
  • Copy-paste install: one snippet of HTML works on any website builder

Frequently asked questions

Is Weight on planets really free?
Yes — completely. PlanckUi widgets are free forever, with no watermark, no usage limits and no credit card. Paid widget platforms charge $15–40 per month for the same embeds.
Do I need an account to use Weight on planets?
No. Click "Copy HTML" and paste it on your site — that's the whole flow. An account is only needed if you want to collect live data (like customer testimonials) and manage it from a workspace.
Does it work on Wix, Squarespace, Webflow, WordPress or Shopify?
Yes. If a platform lets you paste an HTML embed block — and all of them do — Weight on planets works there. The snippet is plain HTML and CSS in an isolated shadow root, so it can't fight with your theme.
Will Weight on planets slow down my website?
No. The widget is a few kilobytes of HTML and CSS rendered locally in your browser — no external requests, no tracking scripts, no layout shift.
