Cursor Crowd
Live cursors of everyone else viewing the page. Each visitor in their own color, on a relay you own.

Setup
1
Deploy your relay: The Deploy to Cloudflare button. Free Cloudflare account is enough; nothing is stored, and the free plan can't bill you.
2
Connect it: Paste the printed URL into Endpoint URL, type any word as Site key.
3
Place it: One instance per page, or once in a shared layout section. On canvas it's a small card; on the live site it's invisible.
4
See it live: Open the published page in two browsers. Turn on Debug status while testing; turn it off before shipping.
5
Lock it down: Set ALLOWED_ORIGINS in wrangler.jsonc to your domain and redeploy. Link the repo README's Configure table.
