Should I demo live during a conference talk?

Rarely. Conference networks, logins and loading states fail in front of the largest audience you will have, and the failure is memorable in the wrong way. A recorded click-through advances on your click, so you keep live pacing without the dependencies.

How do I make a demo readable from the back of a room?

Zoom much harder than feels necessary, use fewer steps since you are also talking, and avoid small text, dense tables and thin grey type. Test on the actual projector if you can -- contrast is always worse than expected.

How do I share a link with a conference audience?

A short URL on the final slide, left up during questions, which is the only moment anyone acts on it -- or a QR code, since a phone is already in their hand. And keep the link live: most talks are watched on video months later.

Using a Demo in a Conference Talk

August 28, 2026

Demoing live on stage is a well-known way to lose ten minutes of a talk to a loading spinner, a login, or a network that stopped working when four hundred people arrived.

The failure is memorable in exactly the wrong way, and it is entirely avoidable.

Record it and drive it yourself

A recorded click-through advances on your click, which means you keep the pacing of a live demo without the dependencies. Nothing loads, nothing expires, nothing needs a network.

You still narrate, still pause on the interesting part, and still look like you are using the product — because you are showing exactly what it does.

Build for a room, not a laptop

Zoom hard. What is legible on your screen is invisible from row twelve.
Fewer steps than usual, since you are also talking.
No small text, no dense tables, no thin grey type.
Test on the actual projector if you can. Contrast is worse than you expect.

The audience cannot write down a URL

People in a talk have their hands full and are not going to transcribe a link from a slide. Put a short, memorable URL on the final slide and leave it up during questions, which is the only time anyone will act on it.

A QR code works better than a URL here, because a phone is already the device in their hand.

The talk keeps working afterwards

Most conference talks are watched more times on video than in the room, months later, by people who then have no way to reach you.

A link that stays live and a demo that stays current turn a one-hour talk into something that keeps producing. Do not retire that URL when the conference ends.
