Kahoot vs Slido: which fits your class, meeting or event in 2026?

• Main job

  Slido's core is audience Q&A with upvoting, moderation and labels, plus polls, ratings, word clouds and surveys; quizzes are a side feature. Kahoot's core is the quiz game, with 13+ question types, team mode and self-paced assignments around it.

• Quiz depth

  A Slido quiz is multiple choice with a timer (20 seconds by default), speed-based ranking and a top-5 leaderboard, up to 100 questions; the free plan allows one quiz per event. Kahoot adds music, true/false, puzzle, type answer and other formats, and shows a leaderboard after every question.

• Where it runs

  Slido works inside PowerPoint, Google Slides, Microsoft Teams and Zoom and natively in Webex, and it retired its participant mobile apps on March 30, 2026, so people join in the browser. Kahoot has Teams, Zoom and PowerPoint apps too, plus a Google Classroom add-on and optional mobile apps for players.

• How participants are counted

  Slido counts every device that joins during an event toward the cap: 100 free, 200 on Engage, 1,000 on Professional and 5,000 on Enterprise. Kahoot counts players per game: 40 free for K-12 teachers, 50–800 on teacher plans and up to 5,000 on top work plans.

• Paying for a one-off event

  Slido's one-time plans cost $60 (200 participants), $240 (1,000) or $1,000 (5,000) for a single event lasting up to 7 days. Kahoot's event plans cost $199 (200), $299 (1,000), $499 (2,000) or $799 (5,000) and stay active for 30 days.

As of October 2026, Slido's business plans are Engage ($17.50/month, 200 participants per event), Professional ($75/month, 1,000, two users) and Enterprise ($200/month, 5,000, three users), all billed annually; Slido doesn't accept monthly payments, but its annual plans don't auto-renew and come with a 30-day money-back guarantee. Educators pay $7/month (Engage, 500 participants) or $12/month (Professional, 1,000), billed annually. On the Kahoot side, teachers pay $36, $84, $144 or $228 a year for 50, 100, 200 or 800 players (Bronze, Silver, Gold, Kahoot! One), and Kahoot! 360 work plans cost $19–$79 per presenter per month, billed annually. For the same $84 a year, a teacher gets 500 participants per event on Slido's education Engage plan but 100 players on Kahoot Silver, and for single events Slido starts lower: $60 instead of $199.
