Omnia — the open-source event platform

What's inside

One platform. The whole event lifecycle.

Born from fourteen editions of running a 2,000-person tech conference — and from every frustration with the tools we used along the way.

Registration & ticketing

Ticket types, early-bird pricing, workshop options with their own capacity, vouchers, group bookings, waitlists — with payments and legally sound invoicing through your PSP.

Call for Papers

A form builder for submissions, review workflows with buckets and a content team, and a speaker portal that keeps everyone informed automatically.

A visitor app that works

Personal agenda with clash warnings, tickets in Apple & Google Wallet, zoomable floor plans, live captions on your own phone — as a native app and on the web.

Feedback & live engagement

One-tap session ratings, live Q&A with upvotes, polls with instant results — and speakers actually get to see their feedback.

Badges & check-in

Badge designer, print-at-home, self-service kiosks and scanning that keeps working when the venue wi-fi doesn't. Stage timers and door signage included.

Sponsors & insight

Packages and add-ons, a sponsor portal, lead retrieval, live dashboards for organizers — and a public stats page that helps you sell next year's event.

Overview of the Omnia platform: admin dashboard, stage timer, attendee app, ticketing, check-in and badges, sponsor portal, live captions and call for papers — all connected to the Omnia core

Yours, entirely

White-label by design

Your brand everywhere. Site, app, e-mails, badges and widgets follow your design tokens — down to your own app in the app stores.
Your infrastructure. One Docker image. Runs on Azure, any other cloud, or a server under your desk.
Your data. EU & GDPR by design, full data export built in. No lock-in, ever.
Your integrations. An API-first platform with webhooks and embeddable widgets — the public API can never lag behind, because our own apps use it too.

How it works

From zero to your event in three steps

Install

Self-host with Docker Compose or deploy the reference setup to your own cloud. A guided health check tells you exactly what's left to configure.

Brand

Colors, logos, fonts, domains — one config makes the website, visitor app, e-mails and badges unmistakably yours.

Run

Open your call for papers, sell tickets, check people in, and give visitors an event experience that finally feels right.
