Embed Doctor
Your <agent-3d> tag is on the page and nothing appears. The console is
empty, the markup looks right, and there is no error to search for. Paste the URL and we
load your real page in a real browser, watch the embed try to boot, and name the one line
to change. Both embeds are checked the same way, so a
<three-d> tag from the v1 loader (including a token-gated one) is as
welcome here as <agent-3d>.
Run a diagnosis
The page has to be reachable from the public internet. Working on localhost or behind a login? .
We run it in a blank sandbox with no CSP and no other scripts, so anything that fails here is a mistake in the markup itself rather than something your site did to it.
Booting chromium, then waiting for the agent to paint its first frame. 0.0s
What gets checked
- The runtime script is present, downloaded, and actually executed
- A Content-Security-Policy silently dropped it
- The bundle was loaded without
type="module" - The element exists and was upgraded to a live component
- The agent id resolves and is publicly readable
- The element has real size and is not hidden by an ancestor
- WebGL is available in the visiting browser
- A canvas was created and painted actual pixels
- Model and manifest requests succeeded
- Mixed content, duplicate tags, and console errors
Nothing is simulated. Every answer comes from your page running in a browser we drive, and every failure carries the evidence that proves it.
