Proficonf is a lightning fast and powerful video conferencing web app. Featuring: - Up to 250 participants - Since we're using WebRTC you don't have to download or install anything. - You can share not only your screen, but also native apps, and web browser tabs. - You can share documents of almost all formats, share YouTube videos (even streams), recorded videos, and audio. - Proficonf has a built-in whiteboard (now you can only draw, but typing will be added soon). - Also, integration with Slack, Google Docs, and Dropbox is planned and will be added after the release. - Proficonf also works in Android mobile web browsers, and we're building iOS/Android app.
