THREAD:// — THE SPATIAL WEB, OPEN FROM DAY ONE

Worlds that link
like pages.

The Thread is an open standard for addressable 3D places. You author a world.json, host it on any web server, and it becomes a walkable world — linked to every other world through portals. No account with anyone. No engine lock-in. The manifest is the medium.

The 30-second model
thread://host/path        ← the address (a place)
   │  resolve
   ▼
world.json  (the manifest) ← what you author: geometry + meaning + portals + presence
   │  fetch + render
   ▼
a walkable world           ← any conformant browser renders it; travelers appear

Portals are explicit links between worlds — which makes the Thread a web, crawlable and open, not a walled platform. The normative specs and governance are public; conformance is decided by a suite, not by us.

Honest status

This is early. The specs are v0.1 drafts. The reference browser (Infinite) ships for Linux, macOS and Windows. The presence relay went live in August 2026 — worlds are just beginning to have people in them. If you build now, you are genuinely early, and the door to shaping the standard is open.
