Best Free Webinar Platforms in 2026 (+ How to Follow Up With Attendees)

Choosing a free webinar platform takes about ten minutes. Figuring out what to do with your attendees after the session ends is where most hosts lose the revenue they worked to earn.

This guide covers both: eight free webinar platforms available in 2026 and the follow-up system that determines whether any of it converts.

Key Takeaways

• Zoom's free plan (100 attendees, 40-minute cap) is the most practical free option for most first-time hosts.
• Popup is the only free platform with unlimited attendees and no session time limit.
• Platform choice accounts for roughly 10% of webinar conversion outcomes; follow-up accounts for the other 90%.
• Industry benchmark data puts the live no-show rate at 51-58%; plan for more than half of registrants to miss the live session.
• A three-email follow-up sequence over 4-5 days consistently outperforms a single replay email.
• Segmenting attendees by engagement before sending follow-up emails is the single highest-leverage action a host can take.

Free Webinar Platforms Compared

The table tells you what you get. What it does not tell you is that every platform on this list ends its involvement the moment your session closes. None of them help you follow up, score, or convert the people who just showed up for your event.

The 8 Best Free Webinar Platforms and Software

1. Zoom (Free Meeting Plan)

Zoom is the default choice for most hosts, and for good reason. Nearly every professional already has it installed, reducing friction at the point of joining. The free plan supports up to 100 participants and imposes a 40-minute cap on group sessions.

The 40-minute limit is the most common objection, and it is manageable. You can restart the same meeting immediately after the timer runs out, and most attendees will rejoin. It interrupts the flow, but it does not kill the session. For sessions under 40 minutes, Zoom free is essentially a full-featured tool.

What Zoom's free plan lacks: registration pages, attendee reporting, and the one-way broadcast format that keeps attendees from unmuting during a presentation. Those features require Zoom's Webinar add-on, which starts at $149/month.

Best for: Hosts with audiences under 100 who run sessions under 40 minutes, or who do not mind restarting.

2. Livestorm (Free Starter)

Livestorm is purpose-built for webinars and runs entirely in the browser, meaning attendees never download anything. The free starter plan caps attendance at 30 participants but imposes no session time limit, which makes it meaningfully better than Zoom for sessions that run 60-90 minutes.

Livestorm's interface is cleaner than Zoom's for a presentation format. Registration pages, automated reminders, and basic analytics come with the free plan. Recording and HubSpot integration require a paid upgrade.

Best for: Coaches and creators running longer sessions with smaller, high-intent audiences.

3. LiveWebinar (Free Plan)

LiveWebinar's free plan is limited to 5 attendees, which makes it impractical for most live events. Where it earns its place on this list is as free webinar software with recording built in: the free plan includes up to 2 hours of cloud storage, which you can use to create a replay link to share with registrants who could not attend live.

The platform also includes polls, screen sharing, and a basic virtual whiteboard on the free tier. If you are running small workshops or recorded demos rather than large broadcasts, LiveWebinar is worth evaluating.

Best for: Small workshops, practice sessions, or hosts who primarily need cloud recording.

4. Streamyard (Free Plan)

Streamyard's strength is multi-destination streaming. The free plan lets you stream simultaneously to YouTube, LinkedIn, and Facebook with up to 5 on-stage participants and unlimited viewing audience on those platforms. If your audience follows you on social channels, this is the highest reach you can get on a free plan.

The trade-off is that you lose the controlled webinar environment. Viewers are watching on social feeds rather than a registration-gated event, which limits your ability to capture attendee data for follow-up.

Best for: Hosts who want maximum reach over controlled audience data.

5. BigMarker (7-Day Free Trial)

BigMarker is not technically a permanent free plan, but the 7-day trial is full-featured and includes up to 1,000 attendees, registration pages, email automation, polls, Q&A, and HubSpot integration. If you have one high-stakes event coming up and want enterprise-level features without a subscription, this is the most powerful option on this list.

The platform's follow-up tools are also the most developed of any free or trial option: automated post-event emails, replay gating, and lead scoring are all included in the trial.

Best for: Hosts with a single large event who need full features for a limited time.

6. Google Meet (Free)

Google Meet's free plan supports up to 100 participants with no time limit, which technically beats Zoom on both dimensions. The reason it ranks below Zoom in practice is that it lacks any webinar-specific functionality: no registration pages, no attendee reporting, no recording on the free plan, and no broadcast mode.

For internal team meetings, Google Meet is excellent. For an event where you need to know who attended and what they engaged with, it falls short.

Best for: Internal events and informal sessions where audience data does not matter.

7. Crowdcast (14-Day Free Trial)

Crowdcast combines a live Q&A format with a community-oriented design. The 14-day free trial includes registration, replay, and basic analytics. The platform charges per registrant rather than per seat, which can make the paid tiers expensive for large lists, but the trial gives you a useful window to evaluate the format.

Crowdcast connects to Zapier, which opens paths to CRM sync and follow-up automation even without native integrations.

Best for: Hosts who run interactive Q&A sessions or community events.

8. Popup (Free Plan)

Popup is a browser-based webinar platform with the most generous free tier on this list: unlimited attendees, no session time limit, and cloud recording included. Registration pages, automated reminder emails, and a replay link are all part of the free plan, which puts it ahead of most free options on feature depth.

The platform is built around the idea that webinars should convert, not just stream. It includes basic follow-up email tools and integrates with Zapier for CRM connections. For hosts who want more than Zoom offers on the free plan but are not ready to pay for Livestorm or Demio, Popup sits in a useful middle ground.

The ecosystem is newer than Zoom's or Livestorm's, but the unlimited attendee cap on the free plan is unique: no other platform on this list supports 500, 1,000, or more attendees without a paid tier.

Best for: Hosts who need a free webinar platform for 500 participants or more, or who want registration, recording, and basic follow-up tools without paying.

What Free Webinar Platforms Do Not Tell You

Every comparison guide for webinar platforms stops at the feature table. Here is what the features do not cover.

The show-up rate problem

Webinar registration does not equal attendance. 2026 benchmark data from 325,000+ webinar attendees puts the average live attendance rate at 49%. A separate analysis of 12,400 B2B webinars shows a median of 41.6% and a mean of 46.2%, with the bottom quartile falling below 30%. The realistic planning figure: roughly half of everyone who registers will not be in the room.

Every platform on this list sends automated reminder emails. None of them help you recover the value from the registrants who did not attend. That population signed up because they cared about your topic. They had a conflict. They are often warmer leads than many people who attended live, and almost no host follows up with them differently than everyone else.

The conversion rate reality

2026 benchmark data shows a 22% CTA click rate for webinars with an active call-to-action. A separate B2B analysis of 12,400 webinars reports that 38% of attendees become MQLs (marketing-qualified leads) and 11.2% enter pipeline on a blended attended-to-pipeline basis. Both figures are for hosts with structured follow-up processes in place, not single-email broadcast sequences.

The hosts who segment by engagement, personalize the follow-up, and reach back out to no-shows consistently convert more of their registered audience than those who send a single generic replay email.

The platform choice affects maybe 10% of that outcome. The follow-up system affects the other 90%.

The no-show gap

Industry benchmark data puts the no-show rate at around 51%. A B2B dataset of 12,400 webinars shows 53.8-58.4% of registrants miss the live session, with the bottom quartile exceeding 70%. Most platforms give you their email addresses via export. Most hosts send the replay link and move on.

A no-show is not a lost lead. It is a person who cared enough to register, had a conflict, and has now not heard from you in a personalized way. A two-email sequence specifically for no-shows, one that acknowledges they missed it and offers the replay with context, converts meaningfully better than including them in the general broadcast.

How to Follow Up With Webinar Attendees

A structured follow-up sequence for webinar attendees runs over 4-5 days and consists of three emails, with the audience split into at minimum two groups: attendees and no-shows.

Step 1: Export your attendee data immediately after the session

Within an hour of closing your webinar, export the attendee report from your platform. At minimum you want: email address, attendance duration (as a percentage of total session length), and any engagement signals your platform tracks (chat activity, poll responses, Q&A submissions).

Zoom exports this data automatically after every session. Livestorm provides an event analytics dashboard. Most platforms have a CSV export option under reporting.

Step 2: Segment by engagement level

Divide your attendees into two groups based on attendance duration:

• High engagement: Stayed for 60% or more of the session
• Low engagement: Stayed for less than 60%

If your platform tracks offer link clicks or chat participation, layer those in. The goal is a signal, not a perfect score. Even a simple high/low split gives you meaningfully different audiences to message.

No-shows form their own third group.

Step 3: Send Email 1 within 3 hours (same day)

For attendees (both groups): Thank them for attending, deliver the replay link, and include one specific insight from the session that they can act on immediately. Keep it under 200 words. The subject line should reference something specific from the session, not just "here is your replay."

For no-shows: Acknowledge that they missed it, deliver the replay link with a brief context note about what they will get from watching, and set the expectation that you will share something useful in the next email. No pitch in Email 1 for this group.

Step 4: Send Email 2 on day 2 or 3

For high-engagement attendees: Share something valuable that you did not cover in the session. A follow-up resource, a framework, a specific answer to a common question from the chat. This email earns attention before you ask for anything.

For low-engagement attendees and no-shows: A shorter version of the same. One piece of value, no pitch. The goal is re-engagement before you make any offer.

Step 5: Send Email 3 on day 4 or 5

For high-engagement attendees: Make a direct, specific offer. Not "check out my program" but a specific call to action tied to the problem your webinar addressed. Include urgency if genuine (a deadline, a limited number of spots) but avoid manufactured scarcity.

For low-engagement attendees and no-shows: A softer offer or a question-based email ("Did you get a chance to watch the replay? Here is the part most people found most useful...") that gauges intent before a direct ask.

How to Score and Prioritize Your Webinar Leads

Not every attendee is equal. Sending the same follow-up to the person who stayed for 90 minutes and asked three questions, and the person who joined for the last 10 minutes, is leaving conversion on the table.

The behavioral signals that predict buying intent from a webinar:

• Attendance duration: 70%+ of the session is the clearest signal of genuine interest
• Chat participation: Asking questions indicates active engagement, not passive watching
• Offer link clicks: If your platform tracks link clicks, this is the highest-intent signal available
• Registration source: Where they found your event often predicts intent (a referral from a customer vs. a cold ad)
• No-show status: Registered but did not attend, separate group, different sequence

Scoring these manually across 100+ attendees after every webinar is where most hosts give up and send one email to everyone. AI-powered tools like Sponja can automate this step: pulling your attendee data, scoring each person by engagement, and drafting personalized follow-up emails for each segment so you start sending within hours of closing the event rather than days.

The platform you host on determines the quality of your live experience. What you do in the 96 hours after the session closes determines whether that experience converts.
