In their own words
Eventzilla
Eventzilla provides event registration, attendee engagement, ticketing and check-in for in-person, hybrid and virtual events, as well as webinars. Organizers can build forms with conditional logic and configure ticket types, discounts, waitlists and approval workflows. The platform also lists attendee email, exhibitor tools and onsite check-in.
Event Hub is a branded attendee mobile app with agendas, networking, interactive sessions, notifications and navigation. Eventzilla connects to over 500 apps through Zapier, including Salesforce, Mailchimp and Google Sheets, and offers an API for custom integrations. Its listed payment gateways are PayPal, Stripe, Braintree, Authorize.net and eWay. It is positioned for conferences and conventions, online events, training and courses, and fundraisers. Free events can use a no-cost plan. Basic costs $1.50 a month, billed per registration, and includes unlimited events and free registration types plus one paid ticket or registration type. A separate plan for premium features on free events costs $49 a month.
OPENPASS
OPENPASS is a free, open-source event management platform that can be self-hosted or used through web and API access. Organizers can publish events in a list-only mode or manage a fuller lifecycle covering discovery, registration, ticketing, check-in and feedback. Discovery includes location-based calendars, an interactive map and local trending topics and organizers. A drag-and-drop form builder supports text, select and checkbox fields. The platform emails QR-code tickets and provides an offline-capable scanner designed to prevent duplicate scans atomically. A real-time dashboard covers registrations, check-ins and capacity utilization, with CSV attendee export. Bulk email and SMS notifications are included. Paid tickets are optional and use Hyperswitch; free events need no payment configuration. The documented deployment uses Docker Compose, PostgreSQL, separate frontend and API services, and session-cookie authentication for protected REST routes. OpenPass is licensed under AGPL-3.0, requiring publication of source changes when a modified version runs as a public service. Federation, waitlists, multilingual support, webhook integrations and fine-grained role permissions are listed as roadmap work.
