Claper
The ultimate tool to interact with your audience (alternative to Slido, AhaSlides and Mentimeter).
The software turns presentations into interactive sessions by allowing presenters to receive real‑time feedback from participants and letting the audience engage directly with the content. It supports features such as live polls, quizzes, and Q&A, aiming to make each participant feel involved and useful during meetings or talks.
It is built with Phoenix, Elixir, and Tailwind CSS, and is offered as a self‑hostable, open‑source solution under the GPL‑3.0 license. A free tier is available without any subscription requirement, and the project includes documentation, a community Discord, and a Reddit forum for support and contributions.
The target users are presenters, educators, and event organizers who need a web‑based tool for audience interaction, especially those who prefer to run the service on their own infrastructure rather than relying on commercial SaaS platforms.
