Why presenters switch.
- A bigger free room
- Claper's free plan stops at 10 attendees. Slidesflow Free fits 50 people in each session, enough for most meetups, classes and team meetings.
- One price for regular presenters
- If you present every week, Pro covers 10 sessions a month for ₹199, instead of paying for each event.
- The question types you already use
- Multiple choice, word clouds, open questions, scales and yes/no on Free; quizzes with a leaderboard, ranking, 100-point votes, number guesses and Q&A with upvotes on Pro.
- Built for conference Wi-Fi
- Joining takes about 17 KB of JavaScript, and answers wait on the phone and send themselves when the connection comes back, so nobody loses a vote to one bar of signal.
When Claper is the better pick: you want to run the software on your own server, or you need the source code. Claper is open source and can be self-hosted; Slidesflow is a hosted service only.
