Run interactive presentations with live audience polls, quizzes, and Q&A, self-hosted.
Claper 3.0 on Ubuntu 24.04 by cloudimg
Claper turns a slide deck into a live, interactive session. A presenter uploads a PDF or PowerPoint deck and the audience joins from any phone with a short code, then answers multiple choice polls, scored quizzes, open questions and emoji reactions in real time over Phoenix LiveView. Self hosted, so presentation content and audience responses stay on infrastructure you control.
cloudimg ships the official Claper container with PostgreSQL behind nginx, with the LiveView WebSocket upgrades proxied out of the box. Every VM generates its own Phoenix SECRET_KEY_BASE, database password and administrator password on first boot, the upstream default admin is never created, and public presenter sign up is blocked. AGPL-3.0 licensed, backed by 24/7 cloudimg support.
