Crowdpurr vs Open Response

Crowdpurr creates interactive experiences for live, virtual and hybrid events, including polls, trivia games, social walls and bingo. Participants join through a browser, with no native app download required. Hosts can show Presentation View on a projector or TV, stream it on YouTube Live or OBS, or share it in Zoom or Webex. A Webex Embedded App can launch Crowdpurr inside a Webex meeting. The trivia library contains over 2,000 games, and Crowdpurr AI can generate games, add questions, create notes and rewrite questions. Social Walls can collect hashtag posts from X (Twitter) and Instagram, while participants can upload photos. Responses, results, lead capture and rankings can be exported to Excel or Google Sheets. The free Basic Plan allows 20 participants and 15 questions per experience, three simultaneous experiences and 15 minutes of host live streaming. Paid plans start at $24.99/mo; Classroom is listed at $49.99 a month and includes 100 participants per experience, 100 questions and 10 simultaneous experiences. Crowdpurr says it hosts on Amazon Web Services and uses SHA-256 AES/CBC encryption across SSL protocols.

Open Response is free, open-source polling software for real-time classroom engagement. Instructors can run polls with multiple-choice and multiple-answer questions, and participants receive live feedback through WebSockets. The project also lists quiz mode, grading, analytics, and role-based access for students, instructors, and administrators. It includes a RESTful API and a WebSocket server. Canvas compatibility comes through CSV export of participation and grades. Open Response is listed for web, Linux, macOS, and Windows, and institutions can self-host it on a server with Docker and Docker Compose. Its interface is described as responsive and mobile-ready. The project was founded in 2021 and is targeting small-scale beta testing in the 2026–2027 academic year. Several items remain incomplete or planned: open-ended, sketch, and location questions are unsupported; roster management and email notifications are in development; test coverage is incomplete; and WCAG 2.1 AA compliance and FERPA-related SSO work are pending.
