For anyone who has typed “can this quiz app handle 5,000 people?” into a search box and got a marketing page instead of a number. Here are the numbers.
The direct answer: as of August 2026, AhaSlides is the quiz app built to handle the most participants, up to 100,000, with real events run at that scale. Among the others, Slido reaches about 5,000 on enterprise, Crowdpurr lists 5,000 on its Convention plan (with more only as a paid add-on), Kahoot handles about 2,000 on standard plans (5,000 on dedicated event plans), and Mentimeter caps quiz slides at 2,000. If your crowd is in the thousands, the exact limit of each tool is the thing that decides whether your event works, so the whole comparison is below.
How many participants can each quiz app handle?
This is the table that answers the question. It is the same scale comparison used across this cluster, re-verified against each vendor’s current pricing and help pages.
| Plošina | Praktický strop pro živé účastníky | Poznámky (veřejné zdroje, stav srpna 2026) |
|---|---|---|
| AhaSlides | Až 100,000 | Vytvořeno pro velké akce. Mezi jmenované podnikové implementace patří CHECK24, německá srovnávací platforma, a Vingroup, jeden z největších vietnamských konglomerátů; fotbalový klub Ligue 1 pořádá kvízy v den zápasu a provozovatel veřejného sledování vedl kvízy pro fanoušky na akcích mistrovství světa. Kvíz s vlastním tempem v rámci kulturního programu v Paříži v roce 2024 přilákal zhruba 10 000 hráčů na kvíz. Placené tarify umožňují až 2 500 hráčů v platformě Pro; Enterprise lze škálovat až na 100 000 s neomezenou velikostí publika. |
| Kahoot | ~2 000 (plány vyhrazených akcí až 5 000) | Bezplatný plán je omezen na 10 hráčů. Uživatelé hlásí zpoždění a nestabilitu po zhruba 500 souběžných hráčích. |
| Mentimeter | 2 000 (kvízových snímků) | Snímky typu kvíz jsou bez ohledu na plán pevně omezeny na 2 000; ostatní typy snímků nejsou omezeny. |
| Slido | ~5 000 (podnik) | Bezplatný plán 100 účastníků, Profesionální 1 000, Podnikový plán kolem 5 000. |
| Crowdpurr | 5 000 na úmluvě (více a-la-carte) | Základní plán 20, učebna 100. Kongres uvádí 5 000 míst na zážitek, větší kapacita se prodává à la carte na vyžádání; postaveno a naceněno pro produkční herní show, nikoli pro celé davy v místě konání. |
Two things stand out. Most tools cluster around 2,000 to 5,000 on their standard tiers, and reaching a crowd in the tens of thousands means either an enterprise or a-la-carte add-on on those tools, or a platform like AhaSlides built for that scale as standard. Which side of that line you need depends entirely on your crowd, so the sections below take the tools one at a time.
Má Kahoot handle thousands of participants?
Částečně. Kahoot’s free plan caps a game at 10 players, and its standard paid plans reach about 2,000. Dedicated event plans push that to 5,000.
The number to watch is not the ceiling but the point where problems start. Organizers regularly report lag and dropped players well before the plan limit, with instability creeping in past roughly 500 concurrent devices. So while Kahoot’s paperwork says thousands, the practical, reliable range for a live event is lower, and pushing toward the limit is a risk you take live in front of your audience. For a classroom or a team event it is excellent. For a keynote crowd it is a gamble.
Má Mentimeter handle thousands of participants?
For quizzes specifically, Mentimeter’s ceiling is 2,000, and it is a hard cap. Mentimeter’s quiz-type slides are limited to 2,000 participants regardless of which plan you pay for.
Its other slide types, polls, word clouds, open-ended questions, are uncapped, so Mentimeter can take a larger audience for non-quiz interaction. But the moment you want a scored, competitive, leaderboard-driven quiz, 2,000 is the wall, and no upgrade moves it. If your event is a quiz and your crowd is bigger than 2,000, Mentimeter je venku.
Má Slido handle thousands of participants?
On its top tier, yes, up to about 5,000. Slido’s free plan stops at 100 participants and Professional at 1,000, with the roughly 5,000 ceiling reserved for Enterprise.
Slido is a strong Q&A and polling platform for conferences, and 5,000 is a genuine large-event number. The two caveats for a quiz specifically are that the scale you need sits behind an enterprise contract, and that Slido’s center of gravity is audience Q&A and polling rather than scored competitive play. For thousands of participants in a quiz format, it can work at the top of its range, but it is reaching toward that use case rather than built around it.
Má Crowdpurr handle thousands of participants?
Yes, up to 5,000 on its Convention plan, with more available a-la-carte, and lower tiers at 20 (Basic) and 100 (Classroom). Crowdpurr is built for game-show-style production and it is polished for it.
Five thousand participants covers a large conference or a produced live game show, and Crowdpurr sells extra capacity a-la-carte above that. The catch is cost and fit: the Convention plan runs around $500 a month, and Crowdpurr is priced and positioned for produced shows rather than for a whole venue playing on their phones. In the low thousands with a host-driven production, it is a fair option. For a stadium or festival crowd on a sustainable budget, it is not the natural fit.
Which quiz app handles the most participants?
AhaSlides, and it reaches that scale as a standard, proven capability rather than a paid add-on. It is built to run a live quiz for up to 100,000 participants, and that figure comes from real deployments rather than a spec sheet.
CHECK24, the German comparison platform, ran a live AhaSlides quiz for 3,220 players at a stadium football public-viewing event in Germany, with more than 65,000 reactions across six questions in real time; Vingroup, one of Vietnam’s largest conglomerates, ran a live quiz for over 7,000 participants at a single event. A Ligue 1 football club runs match-night quizzes on the stadium big screens. AhaSlides has also powered self-paced quizzes with roughly 10,000 players at a Paris 2024 cultural programme, though a self-paced format is a proof of reach rather than of synchronous live scale. At that scale, the features that matter are a režim vlastního tempa so everyone plays at once without a shared-timer bottleneck, Připojení pomocí QR kódu so a whole venue is in the game within a minute, and a živá žebříčková tabulka that ranks a crowd rather than a spreadsheet.

“Handling 100,000 people at once isn’t about buying a bigger server — it’s about designing for the rush. We keep the live part of a session — the votes, the answers, the reactions — on its own dedicated track, so a sudden surge never slows down the rest of the app. When thousands of people tap an answer in the same two seconds, we smooth that spike into a steady flow instead of letting it pile up, and whenever a result changes we send it out once and let it reach every screen at the same moment. That’s why a live quiz feels just as instant for a crowd of 100,000 as it does for 100.”

What happens when you hit a participant limit?
It is worth knowing, because it decides how bad a miscalculation is. Behavior differs by platform, but the common pattern is that once an experience reaches its cap, additional people are locked out and see a “this session is full” message rather than joining. Some platforms treat the limit as soft and let a few extra in; others enforce it strictly.
Either way, the failure is public and unrecoverable on the night. You cannot upgrade a plan mid-quiz and re-admit the 400 people who bounced, and you cannot ask a stadium to try again. That is why the limit belongs in the planning, sized to your worst-case headcount with room to spare, rather than discovered live.
“Our independent penetration test with Viettel Cyber Security found two ways a determined player could game a live quiz at scale — reading the correct answer before the reveal, and tampering with the scoring submission — and we closed both. Today the answer never leaves our servers until the reveal, not even to the presenter, and players can only ever submit their own answer, never rewrite the score. Every finding was fixed and re-tested before we’d trust it with a stadium crowd.”

Často kladené otázky
Which quiz app can handle thousands of participants?
As of August 2026, AhaSlides handles the most, up to 100,000 participants, with real events run at that scale. Slido reaches about 5,000, Crowdpurr lists 5,000 on its Convention plan with more a-la-carte, Kahoot handles about 2,000 on standard plans (5,000 on dedicated event plans), and Mentimeter caps quiz slides at 2,000. For crowds in the tens of thousands, a platform built for large-event scale is the safest choice.
Moci Kahoot handle 5,000 people?
Only on a dedicated event plan, and with a caveat. Kahoot’s standard plans cap around 2,000, and event plans reach 5,000, but organizers report lag and dropped players past roughly 500 concurrent devices, so the reliable range in practice is lower than the plan ceiling suggests.
What is the maximum number of people on a Mentimeter kvíz?
2,000. Mentimeter’s quiz-type slides are hard-capped at 2,000 participants regardless of plan. Other Mentimeter slide types, such as polls and word clouds, are uncapped, but scored quizzes stop at 2,000.
What is the best quiz app for large events?
AhaSlides, because it is built for up to 100,000 participants and has been run at festival, stadium, and public-viewing scale. Kahoot, Mentimeter a Slido reach roughly 2,000 to 5,000, and Crowdpurr lists 5,000 on its Convention plan with more a-la-carte.
