this is a real page

Your users see each other. On your site.

Below is our live demo, running the widget you'd ship — comments panel, pinned thread, presence, and the room's heartbeat. Open it in two tabs and watch them sync.

what's in the widget

Everything a multiplayer page needs.

One tag adds the full collaboration layer. Every feature is enforced server-side per environment, so you decide what each tenant gets.

Comments pinned to pixels

Threads anchored to the exact spot they're about. Creators drag their pins; everyone sees the move live.

Live cursors & clicks

Color-coded cursors with names, click ripples, and shared text selections — throttled and smooth.

Presence & follow

Who's here, live in the toolbar. Click a teammate to follow their scroll for walkthroughs and reviews.

Notifications that navigate

Mentions, replies, and reactions land in an inbox. Click one and the page scrolls to the pin and opens it.

Media notes

Attach images, in-browser voice notes, and video clips to any comment. Lightbox and players included.

P2P shared data

Optional CRDT-backed SharedMap, SharedList, and SharedCounter over WebRTC — with server persistence for late joiners.

Self-hosted, multi-tenant

Your Postgres, your keys, your data. Tenants, environments, and API keys managed in the admin panel.

Themeable to the pixel

CSS custom properties for every surface — brand colors, dark mode, header caps, fonts, radii.

quick start

Live in three steps.

Your backend mints a short-lived token with your secret key; the widget does the rest. Full walkthrough in the Quick Start guide.

the hard part, solved

Pins that survive your next redesign.

Percentage-based pins drift the moment a layout reflows. Pulse anchors every pin with barycentric coordinates against three stable DOM landmarks, then degrades gracefully through four tiers instead of disappearing.

✓Tier 1–2: triangulated against 3 landmarks; still solves with 2
✓Tier 3: element-relative offset when landmarks vanish
✓Tier 4: document-fraction fallback — a pin never just vanishes
✓Movable: creators drag their pins; moves sync and persist

Pulse is in private beta.
