Publish once. Embed anywhere.

An iframe tag. A web component. A downloadable MP4 on Pro. The same demo, wherever your audience already is.

One-line iframe embed

Drop a single iframe tag on any page. Auto-resize via postMessage. Completion events fire to the parent window so you can hook them into your analytics or onboarding state machine.

<heimdall-demo> web component

When you need style isolation or framework-agnostic embedding, use the web component. It wraps an iframe internally so your CSS never bleeds in, and exposes the same postMessage API for variable injection and completion hooks.

Visibility: public, password, or private

Public demos are open to anyone with the link. Password demos require an unlock token (the player handles the form). Private demos require a workspace login — useful for internal walkthroughs and pre-launch reviews.

Embed-domain allow-list

Restrict where your demo can be embedded. Wildcards supported. The player enforces it via CSP frame-ancestors so a malicious site cannot iframe your private deal demo onto a competitor page.

MP4 export (Pro) Pro tier

Render any published demo to a full-fidelity MP4 you own outright. Use it in cold-outreach DMs, paid social, sales decks, or anywhere an iframe won't fit. No HeimdallPresent player required for playback.
