Why omul for universities
Built for lectures, seminars and tutorials
From a quick knowledge check to a quiz with a leaderboard — at terms that fit an education budget.
40% off for education & non-profit
Universities, institutes and non-profit organizations get the entire pricing ladder reduced by 40% — from a small seminar to a large faculty.
Self-host in your data center
The licence for omul is the AGPLv3. Your data center can run it in-house — with no license fees and full control over your data.
Students need no account
The audience joins with a 6-digit code — no email, no login, no app. No personal data is created in the lecture hall.
The whole lecture hall joins in
No participant limit. Whether it's a seminar of 20 or a lecture of 800, everyone takes part at once, with no per-head surcharge.
Every format for teaching
Polls, word clouds, a quiz with a leaderboard, Q&A and scales — from a quick comprehension check to a playful contest.
The cost comparison
What Mentimeter costs per lecturer — and what you pay with omul
Mentimeter's education plan runs about 132 € per year per lecturer (list price, as of 03.07.2026), and its learning-management-system integration sits in the Enterprise package. With several lecturers, that adds up fast. That is the maths omul flips.
- Mentimeter Edu: about 132 € per year per lecturer (list price, as of 03.07.2026).
- LMS integration at Mentimeter is Enterprise-only.
- omul: 40% off for education & non-profit on every plan.
- Self-hosting in your own data center: free under the AGPLv3.
- Unlimited participants — the price doesn't scale with the lecture hall.
Pricing
The full pricing ladder — with the education discount
From a free start to a plan for the whole faculty: the 40% education and non-profit discount applies at every tier. And if you self-host, there's no license fee anyway.

Open source among peers
We're in good company
Particify has shown academia in the DACH region what good open-source audience response looks like — open, self-hostable and used at many universities. Those values omul shares. On top, we add more polish for business use and a broader set of formats, including a quiz with a leaderboard. Pick the tool that fits your institute — both keep teaching open and in your own hands.
Frequently asked questions from universities
Is there an education discount?
Yes. Universities, institutes and non-profit organizations get 40% off the entire pricing ladder — at every tier, from the smallest plan to the largest. And if you self-host, there's no license fee at all under the AGPLv3.
Can the university self-host?
Yes — omul is licensed under the AGPLv3 and runs in your own data center — with no license fees and full control over your data. This is the very model Particify established in DACH academia; omul follows the same open principle.
Do students need an account?
No. The audience joins with a 6-digit code — no email, no login, no app. That means no personal data is created in the lecture hall, a clear GDPR advantage.
What does Mentimeter Edu cost?
Mentimeter's education plan runs about 132 € per year per lecturer (list price, as of 03.07.2026). Its LMS integration is reserved for the Enterprise package. With several lecturers, that adds up quickly.
How is omul different from Particify?
Particify is an established, open-source audience-response project from DACH academia — and we hold it in high regard. The open-source and self-hosting values omul shares, but puts more emphasis on polish for business use and offers a broader range of formats, such as a quiz with a leaderboard. Which tool fits best depends on your use case.
How many participants are supported?
As many as fit in the lecture hall. There is no participant limit in omul, and the price doesn't depend on group size — a seminar or a mass lecture makes no difference.
