Typically, quiz maker tools offer three to four plans - with their entry plan starting around $30 a month, and white-labelled plans with more features will often start at $50 a month. Enterprise plans can vary from Riddle’s $199 a month to Qzzr’s $10,000. One key difference - companies put different usage limits in how many quiz takers or leads you get per month: - Involve.me, for example, limits you to 1,000 quiz takers a month on their Starter plan.  - Outgrow and Typeform cap your monthly leads in their mid-level plans to 5,000. - Riddle is the only online quiz maker we reviewed with completely unlimited usage - on all plans. Some quiz makers offer completely free plans - like Involve.me and Typeform - but severely limit the features available, cap the number of leads you can collect, plus generally provide no customer support.
