Running webinars — for demos, training, lead-gen — needs a platform built for one-to-many with registration, and the pricing models are all different shapes.
| Model | Entry | Scales by | |
|---|---|---|---|
| Demio | flat monthly per host | ~$63/mo (Starter, annual); up to $199+ | attendee capacity + session length caps |
| Livestorm | credit-based | €2.50 per unique attendee | number of people who actually show up |
| Zoom Webinars | add-on to Zoom Workplace | $79/mo (500 attendees) | attendee tier ($340/mo for 1,000; ~$6,490/yr for 10,000) |
Demio is the marketer's pick for small-to-mid webinars — a polished registration and live experience, good automation, and flat per-host pricing from ~$63/month. Watch the session-length caps (3 hours on Starter, up to 10 on Premium), which bite if you run long training sessions. Predictable cost as long as your audience fits your capacity tier.
Livestorm bills per unique attendee at €2.50 each — you pay for people who show up, not registrants who don't. For frequent, smaller webinars (50–100 attendees) this can be very cost-effective. For occasional large events it gets expensive fast: 3,000 live attendees is €7,500 for that one event. Great for a steady cadence of modest webinars, punishing for big one-offs.
Zoom Webinars is the infrastructure choice — it's an add-on to a Zoom Workplace plan, starting at $79/month for 500 attendees and scaling by tier. Nobody gets fired for picking Zoom: the reliability at large scale is unmatched, attendees already know the interface, and for 5,000+ person events it's the safe option. Less marketing-automation polish than Demio or Livestorm.
Regular mid-size marketing webinars: Demio for flat pricing, or Livestorm if audiences are small and you want to pay only for attendance. Large or mission-critical events where reliability trumps everything: Zoom Webinars.
