The Slido alternative for the whole session
Slido is great for questions from the floor. Quack does moderated Q&A with upvotes too, and adds scored quizzes, word clouds, scales and 20+ formats, free for up to 300 players, with no per-event poll limit.
Quack covers Slido's core (live polls, word clouds, upvoted Q&A) without the free plan's three-polls-per-event limit, and adds a full game layer Slido doesn't have: scored quizzes, streaks, podium. Paid starts at $12 a month, billed monthly; Slido's subscriptions bill annually.

Unlimited polls per event
Slido's free plan allows three polls per event. Quack decks have no per-event limits: run as many polls, word clouds, scales and quiz questions as the session needs, for up to 300 players, free.
Q&A, and the rest of the session too
Audience questions with upvotes and host moderation are built in. So are the moments beyond Q&A: a scored quiz to lift the energy, a word cloud to open, emoji reactions floating across the big screen and a comment the host pins for everyone. One deck carries the whole arc of a session.
A price one person can expense
Quack Plus is $12 a month with a 14-day trial: no annual contract, cancel anytime. It adds your brand on every slide, deck co-editing and CSV exports. Slido's subscriptions bill annually; one-off event passes exist but reset with every event.
When Slido is the better fit
Honest answer: sometimes it is. Pick Slido if any of these describe you.
- Your Q&A runs inside Webex, Teams or PowerPoint and the native integrations are the point; Slido is part of Cisco and lives in those rooms.
- You moderate question queues for conferences with thousands of attendees and need that scale today.
- You only ever need Q&A plus a couple of polls, and a one-off event pass fits how rarely you host.
