Open-source Whova alternatives

Hi.Events is an open-source event ticketing and management platform for selling tickets online to conferences, nightlife events, concerts, club nights, workshops and festivals. It can be self-hosted or used through Hi.Events Cloud, giving organizers control over branding, checkout and data.

On the ticketing side it handles free, paid, donation and tiered tickets, recurring and multi-date events, sold-out waitlists, promo codes, product add-ons, and tax, fee and capacity management. Organizers can design event homepages, create customizable PDF tickets and embed a ticket widget. Attendee tools include custom checkout questions, search and CSV or XLSX export, full and partial refunds, bulk messaging and QR code check-in with scan logs.

Reporting covers a sales dashboard, affiliate tracking, daily sales, product, promo code, revenue and tax reports, and outgoing webhooks, and the platform has multi-user roles. Hi.Events is positioned as an open-source alternative to Eventbrite, Tickettailor and Dice.fm, and is built with PHP, Laravel and React. The interface is translated into many languages.

Pretix is a ticket shop application for events such as conferences, festivals, concerts, tech events, shows, exhibitions, workshops and barcamps. It lets organizers set up an online ticket shop, sell tickets and manage attendees. The core is written in Python with Django, and the project's website also presents it as a service sold to organizers across many industries.

The vendor describes a customizable ticket shop, a marketing toolkit, direct payments, individual tickets, check-in and box office tools, and reports and statistics. Around the core platform sit related products, including pretixPOS as a cash register app, pretixSCAN for access control and live badge printing, pretixKIOSK as a ticket vending machine app, pretixLEAD for exhibitor networking and Venueless for virtual and hybrid events. Hardware can be rented too.

Industries named on the site include conferences, trade fairs, museums and libraries, parks and zoos, workshops, concerts and theatre, digital events and festivals. The service is described as GDPR compliant and multilingual. The vendor publishes a pricing page for its hosted offering and can be contacted for individual use cases, while the underlying platform is available as open-source code.

pretalx is conference management software that covers the path from an open call for papers to a published schedule. Organizers collect proposals, review and select talks, email speakers and build the program, all within one system, whether the event is a small meetup or a multi-room conference.

It supports anonymous or open review, events with or without tracks, single or parallel rooms, and emails to all submitters or a chosen subset that can be proofread or edited before sending. The schedule can be built around speakers' needs, and changes are published and communicated automatically. A plugin ecosystem lets organizers adapt it to particular requirements, and custom plugins can be commissioned.

pretalx is open source and built with Python and Django, so organizers can run it on their own servers. The project also operates pretalx.com, a hosted service where an event can be set up in a few minutes and tried for free before committing; pricing is published on that site.
