ON24 Alternatives

BigMarker is ranked by five of the eight competitor guides we read, as are Bizzabo and GoTo Webinar, and it is the closest match to what ON24 does: live, on-demand, simulive, evergreen and 24/7 webinars, webinar series, virtual and hybrid events, media hubs that work like ON24's content hub, and registration pages you build without a developer. It runs in the browser for attendees and hosts. Plans are sold on a quote, but unlike ON24 the contents of each tier are published. Basic covers up to 1,000 live attendees, one host license and up to nine webcams on screen. Enterprise raises that to 10,000 live attendees and four host licenses, and adds one CRM or marketing automation integration, simulive and evergreen webinars, breakout rooms, API access and a customer success manager. Enterprise+ goes up to 500,000 live attendees, six host licenses, two CRM integrations, white-labeled domains, live captioning and translation, SSO and a negotiable DPA.

How it reads against ON24: BigMarker counts live attendees, not registrants, and lets an unlimited number of people register. The subscription renews every year, and you can cancel the auto-renewal at any time during the term. Each plan stores up to 100 on-demand webinars; past that you buy more storage. If you sell tickets, BigMarker takes a 5% transaction fee through Stripe or Authorize.net. To push BigMarker registrations into other tools, see our BigMarker and Zapier integration guide or our BigMarker and Make guide.

Zoom Webinars is the alternative that asks the least of your attendees and your speakers: most of them already know the Zoom client, and the webinar room adds chat, reactions, polls, Q&A, custom backgrounds and downloadable performance reports. Pricing is public. Webinars costs $83.33 per user per month billed annually for webinars up to 500 attendees. Webinars Plus, at $290.83 per user per month billed annually, adds Zoom's modern webinar platform, pre-recorded sessions run like live, a backstage for speakers, AI-generated event pages and on-demand video. Events, at $415.83 per user per month billed annually, adds multi-session virtual events with ticket types, a lobby, sponsors and networking.

How it reads against ON24: Webinars at $83.33 a month comes to $999.96 a year for one host and 500 attendees, a public number you can approve without a negotiation. The unit is the user, meaning a host license: two teams that run webinars at the same time need two licenses. Zoom says it hosts more than 9 million webinars a year, which is the reliability argument ON24 buyers usually make. What you give up is ON24's depth on engagement scoring and content hubs; Webinars Plus closes part of that gap at three and a half times the price. If you are already thinking about leaving Zoom itself, our guide to switching from Zoom covers the meetings side.

GoTo Webinar has run B2B webinars for a long time, and five of the eight competitor guides we read still rank it. It is a straightforward webinar room with registration, automated reminder and follow-up emails, polls, handouts, live Q&A, reporting and a mobile app. Plans are public and can be billed monthly or yearly. Reach costs $59 a month billed annually or $69 billed monthly, with one organizer seat and up to 500 participants. Elevate, the most popular plan, costs $103 a month billed annually or $129 monthly, and goes up to 1,000 participants with branded webinars and custom URLs, cloud recordings, AI summaries and transcripts, recordings run as live events, and breakout rooms. Complete is sold through sales: custom organizer seats, up to 3,000 participants, live streaming to unlimited attendees, paid events and certified training, registration source tracking and a GoTo Meeting license.

How it reads against ON24: Reach comes to $708 a year on annual billing, or $828 if you pay month to month, and you can stop when you want. Watch the jump at 500 participants: going from Reach to Elevate on annual billing moves you from $59 to $103 a month, a 75% increase, just for the second 500 seats. And if you want to know which channel brought each registrant, that tracking sits in the Complete plan.

Demio is the alternative for a small marketing team that wants webinars to be a lead source, not a production. Attendees join in the browser, and hosts get registration pages, reminders, polls, handouts and analytics. Four competitor guides rank it. Plans are public. Starter costs $45 a month billed yearly or $63 billed monthly, for a single host, a 50-attendee room and sessions up to three hours. Growth costs $117 a month per host billed yearly, with rooms of 150, 500, 1,000 or 3,000 attendees and sessions up to eight hours. Premium costs $196 a month per host billed yearly, with sessions up to ten hours, up to ten people on stage, a dedicated success manager, custom domains and Demio AI.

How it reads against ON24: Starter is $540 a year on yearly billing, and Growth is $1,404 a year per host, so a team with one host can run a full webinar program for less than 2% of the buyer-reported ON24 median. The unit to watch is the host: on Growth, each simultaneous event needs its own host. And the trial is narrow: 14 days with Growth features, limited to 20 attendees and one-hour sessions, so you can't rehearse a real 200-person webinar before paying. Run your pilot on a monthly plan instead. Demio connects to automation tools; see our Demio and Zapier integration guide.

Bizzabo is not a webinar tool first. It is an event management platform for in-person, hybrid and virtual events, with webinars as one format among others, and that is exactly the case for teams that bought ON24 alongside a separate conference tool. It covers registration and ticketing, an event website builder, email campaigns, a mobile event app, a virtual venue with chat, polls and Q&A, simulive streaming, breakout rooms, onsite check-in and badges, and reporting. Bizzabo publishes a price: the Event Experience OS costs $499 per user per month billed annually, with a three-user minimum, starting at $17,999 per year. Unlimited events and unlimited registrations are included.

How it reads against ON24: three users at $499 a month for twelve months come to $17,964, so the $17,999 floor is the real entry ticket, whatever your webinar volume. Some pieces ON24 buyers expect sit in premium add-ons: the Virtual Production Suite for studio-quality live video and on-demand video, and the martech and CRM integrations with HubSpot, Marketo, Salesforce MCAE (Pardot) and Oracle Eloqua. Price those before you compare. Bizzabo lists SOC 2 Type II, ISO 27001, GDPR, CCPA and ADA compliance. For other event platforms, see our ranking of the best event management software.

Contrast is a browser webinar platform aimed at B2B marketing teams, with a free plan for small teams. It runs live, pre-recorded and recurring webinars with branded registration pages, reminder emails and calendar invites, chat, Q&A, polls and CTAs tracked to the CRM, and it turns each recording into blog posts, newsletters, LinkedIn posts and subtitled clips with its AI tools. Every plan includes unlimited team members, unlimited webinars and unlimited hosts and speakers. The free plan lets you run as many webinars as you like with up to 30 unique registrants per month. Pro starts at $99 a month billed yearly for 100 registrants per month, with 250 and 500 tiers above it, and webinars up to two hours. Advanced, on a quote, goes up to 10,000 yearly registrants and four-hour webinars, with SSO, an API and webhooks.

How it reads against ON24: Pro at $99 a month comes to $1,188 a year. The unit is the unique registrant per month, and the count resets every month, so a busy month with two big webinars can push you to a higher tier even if most people never show up. On the free plan, registrations are restricted once you pass the limit. Its HubSpot sync is deep (registrants, watch time and engagement on the contact timeline), while Salesforce is an add-on.

Livestorm is a browser-based webinar and virtual event platform, ranked by four of the eight competitor guides we read. Attendees join without downloading anything, and hosts get registration pages, email cadences, polls, Q&A, file sharing, on-demand and automated events, and replay. Its pricing model is the most unusual here. You buy a yearly pack of attendee credits and spend one credit for each unique person who attends a session, live, on replay or on demand. Pro costs $3.00 per attendee on the default 400-credit pack, so $1,200 a year, with up to 3,000 live attendees per event, sessions up to four hours, unlimited events and unlimited team members. Team members don't use credits, and people who register but never show up are not counted. Enterprise, on a quote, adds sessions up to 12 hours, enterprise integrations, custom analytics and a dedicated success manager. A free plan, meant for evaluation, gives 30 attendee credits a year and 30-minute sessions, with no credit card.

How it reads against ON24: the per-attendee model fits irregular programs better than ON24's event tiers, but read two lines carefully. If you reach your quota, new attendees can't join sessions until you upgrade to a higher yearly tier. And the native HubSpot, Salesforce, Marketo, Pardot and Microsoft Dynamics integrations are marked Enterprise plan only, so on Pro your CRM sync runs through Zapier or the API.
