A webinar that nobody can find the registration link for might as well not exist. Webinar software handles the whole chain — registration, streaming, engagement, and the follow-up analytics that decide whether marketing calls it a win.
This category splits between enterprise demand-gen platforms built around first-party data (ON24), the big video-conferencing names extending into webinars (Zoom, GoTo), marketing-team-friendly tools with built-in AI chat handling (Demio, WebinarGeek), a credit-priced platform that turns recordings into shareable clips automatically (Livestorm), and a scale specialist built for massive audiences (BigMarker). AI content repurposing is everywhere in this category; MCP support, so far, mostly isn't.
Every price, feature, and AI/MCP/API claim below came from each vendor's own site as of August 2026, checked directly rather than pulled from a comparison roundup.
Quick summary: Zoom Webinar is the only platform here with a confirmed official MCP server. ON24, GoTo Webinar, Demio, Livestorm, and WebinarGeek all ship real AI features — mostly content repurposing and chat automation — without a vendor-maintained MCP server yet. BigMarker had no AI feature confirmed but scales to the largest audiences.
Why You Need Webinar Software
- Turn one live session into weeks of usable content: AI-powered clipping and repurposing tools automatically pull highlight moments, blog posts, and transcripts out of a single recording.
- Capture first-party intent data marketing can actually act on: Engagement analytics down to the individual level show who's actually paying attention, not just who registered.
- Run events without a producer glued to the controls: Automated and Simulive formats play pre-recorded content on a schedule while still feeling live to attendees.
- Handle audience questions without a moderator answering every one: AI chat assistants field common attendee questions live, freeing the host to focus on the presentation.
- Scale from a 50-person training session to a 10,000-person launch: The right platform handles both without switching tools halfway through a growing program.
Best 7 Webinar Software in 2026
1. ON24
ON24 doesn't think of a webinar as an event that ends when the stream cuts off. Its whole platform is built around turning one session into ongoing, personalized content and first-party data.

Best for: Enterprise B2B marketing teams that want a webinar to generate ongoing personalized content and first-party data, not just a single event.
2. Zoom Webinar
Zoom Webinar rides on the same infrastructure and MCP investment as the rest of Zoom's platform, which puts it ahead of most of this list on AI-agent connectivity.
Pricing: Webinars starts at $66.67/month for 300 attendees; Webinars Plus starts at $99/month for 100 attendees with a per-attendee option; Events starts at $149/month for 100 attendees, also with per-attendee pricing — all require a Zoom Workplace Pro subscription.

Best for: Teams already on Zoom that want webinars with the same official MCP and AI investment as the rest of the platform.
3. GoTo Webinar
GoTo Webinar has been the safe, boring choice for corporate training programs for years, and Simulive — playing a recording as if it were live — is still one of its most useful tricks.

WebinarGeek puts AI analysis on its cheapest plan rather than saving it for the top tier, which is a genuinely different pricing philosophy than most of this list.

Final Thoughts
AI content repurposing has become close to standard in this category — five of the seven platforms here turn a recording into clips, summaries, or chat automation without extra tooling. MCP hasn't caught up yet: Zoom Webinar is the only platform with a confirmed, vendor-maintained MCP server, inherited from Zoom's broader platform investment rather than built specifically for webinars.
Running enterprise demand-gen programs that need to prove ROI? ON24. Already living in Zoom for meetings? Zoom Webinar is the obvious extension, MCP support included. Need the cheapest way to get AI chat automation? WebinarGeek. Want to pay only for attendees who actually show up? Livestorm. And if the event is measured in tens of thousands of attendees, BigMarker is built specifically for that scale.
