Most quiz tools sell a ladder: a cheap plan with a low player cap, a middle plan that unlocks question types, and a top plan with the reports. You end up paying for the tier that removes the one limit that annoyed you. ZappyQ has one Host Plan because the same product serves a class of 30 and a company kick-off of 300.
The free plan is a real plan, not a trial. Build as many quizzes as you want, use all six question types, try the AI quiz generator ten times and host live games for up to 25 players with reports on screen. Hosting a live game needs a free account; building a quiz does not. When you need more players, monthly AI drafts or CSV export, the Host Plan adds exactly those three things. See how that compares with other tools on the Kahoot! alternatives page.
