WebinarStack vs EasyWebinar

EasyWebinar runs live and automated webinars from $44 monthly, but its $44 Launch plan includes no automated webinars. WebinarStack is pre-recorded only, from $99 monthly for 1,500 attendees, with 18 automation triggers firing email, SMS and webhooks; Meta Conversions API starts on Growth. Choose EasyWebinar for live, WebinarStack for automation depth.

Should I choose EasyWebinar or WebinarStack?

Choose EasyWebinar if you will ever present live, want live and automated webinars in one subscription, or need to multistream. It does more webinar formats than WebinarStack, and its entry price is lower.

Choose WebinarStack if your webinars are pre-recorded and the valuable part is what happens after someone watches: who gets which email, SMS, webhook or offer, based on watch time, poll answers and clicks. WebinarStack does one format and automates it in more depth.

Where does EasyWebinar beat WebinarStack?

In seven places, and the first one decides it for many buyers.

• WebinarStack cannot run a live webinar in any form. It is a pre-recorded and simulive platform by design, while every EasyWebinar plan includes true live webinars. The word "live" in trigger names such as "Live Completed" refers to the scheduled session, not a broadcast.
• EasyWebinar starts at $44 monthly against WebinarStack's $99, so at entry WebinarStack costs more than twice as much.
• EasyWebinar has years of third-party reviews on G2, Capterra and TrustRadius. WebinarStack has no listing or review on any of them yet.
• EasyWebinar's "EasyCast multistreaming" streams one webinar to YouTube, LinkedIn, Facebook and other destinations at once. WebinarStack has no equivalent.
• EasyWebinar's "Paid webinars" feature covers paid registration, built-in checkout and paid replay access. WebinarStack relies on your existing checkout, and its Stripe link attributes a purchase to a webinar after the fact, which is not in-room checkout.
• EasyWebinar ships an AI Webinar Funnel Builder, script generator, registration page builder and email generator. WebinarStack has no AI generation features at all.
• On Growth and above, WebinarStack chat forwards to Slack and replies thread back to the attendee. Answering attendees live as a presenter is a different thing.

How does EasyWebinar pricing compare with WebinarStack?

The cheapest EasyWebinar plan that runs an automated webinar is Growth at $116 monthly for 1,000 automated viewers. WebinarStack Starter is $99 monthly for 1,500 attendees. That is the one like-for-like comparison where WebinarStack costs less, and it holds only at that plan.

EasyWebinar list prices:

| Plan | Monthly | Live attendees | Automated viewers | | --- | --- | --- | --- | | Launch | $44 | 50 | Not included | | Growth | $116 | 200 | 1,000 | | Pro | $198 | 500 | 2,500 | | Scale | $349 | 1,000 | 5,000 |

WebinarStack list prices:

| Plan | Monthly | Annual | Attendees per month | Seats | | --- | --- | --- | --- | --- | | Starter | $99 | $990 | 1,500 | 1 | | Growth | $199 | $1,990 | 4,000 | 3 | | Pro | $350 | $3,500 | 10,000 | 10 | | Scale | Custom | Custom | Custom | Custom |

Attendee overage on WebinarStack is $0.08 per attendee beyond the allowance. See pricing for the bandwidth and storage allowances, which are metered separately.

The two vendors meter differently, so the numbers are not interchangeable: EasyWebinar counts live attendees and automated viewers separately, while WebinarStack counts total attendees per month. EasyWebinar was also running a Black Friday offer on its Pro plan when this was checked, which is not list pricing and is not used here.

WebinarStack Starter includes none of the gated capabilities: no Adaptive Webinar branching, no WebinarStack CDN hosting, no Meta Conversions API and no Slack integration. Those start on Growth at $199, and on Starter video is embedded from YouTube or Vimeo. For a price-led comparison with more options, see cheaper alternatives to EasyWebinar.

Where does WebinarStack's automation go deeper?

WebinarStack ships 18 built-in automation triggers, grouped as 13 behaviour, 3 time and 2 branch.

• Behaviour (13): Registered · Joined webinar · Left webinar · Didn't show up · Watched at least X minutes · Watched at least X% · Completed the video · Live Completed · Replay Started · Replay Completed · Clicked an offer · Responded to a poll · Sent a chat message (optionally keyword-matched)
• Time (3): Before session (configurable offset) · After session (configurable offset) · Time elapsed after event
• Branch (2): Branch taken · Segment completed. These are the two Adaptive Webinar triggers, which need Growth or above.

Nine of the 18 are published to the integrations trigger catalogue that Zapier and Make read: Registered, Joined, Didn't show up, Watched at least X%, Live Completed, Replay Started, Replay Completed, Clicked an offer and Responded to a poll. The other nine are dashboard-only. The Zapier app itself is distributed by public invite link rather than listed in Zapier's App Directory, and the Make app is not published yet, though its server side is in place.

There are five actions: email, webhook, email-platform integration (Kit, ActiveCampaign, Mailchimp or MailerLite), SMS and Meta Conversions API. The public REST and MCP API exposes four of them; SMS is dashboard-only. Meta Conversions API requires Growth or above. See features for the full list.

How do watch-time rules, poll routing and webhooks work?

Watch time. Thresholds work in two units, minutes (no upper bound) and percent (1 to 100), and are available both as triggers and as conditions. A rule fires when a viewer crosses the threshold, tracked by a session-scoped high-water mark rather than on every heartbeat, so a viewer who scrubs backwards does not re-fire it.

Poll answers. Poll logic lives in two places. Automation conditions use poll_answer, the answer value, with the operators ==, !=, >=, <=, >, < and contains; and poll_answered, the set of poll IDs a viewer has answered, which is a membership check and so takes == and != only. The trigger is poll_response ("Responded to a poll"). Adaptive Webinar branches the video itself on a poll answer, on Growth and above. Conditions are AND-only: no OR and no nested boolean logic.

Webhooks. Payloads are signed with HMAC-SHA256 in the header X-WebinarStack-Signature: sha256=<hex>. Each delivery has a 10-second timeout per attempt and up to 3 retries with exponential backoff. Every attempt is recorded with its response code, and deliveries that exhaust their retries land in a dead-letter queue.

If you are building against it, one detail matters: the stable 68-character event_id used for idempotency is carried in the payloads sent to Zapier and Make, not in the webhooks you configure yourself. A webhook you set up as an automation action receives event_type, attendee, webinar, event_data and timestamp, and deduplication for those happens server-side before dispatch.
