Hopp
What it is
Hopp is an open-source screen-sharing and remote pair-programming app aimed at developers and engineering teams. Participants can share and control any application on a teammate’s screen with their own keyboard and mouse; Hopp states latency is under 100 ms. Rooms accommodate up to 10 people, and screen sharing defaults to 4K. Shared cursors, drawing, and annotations support collaborative work such as code reviews, debugging, mob programming, and onboarding. Hopp also advertises active noise-cancelling audio and a Slack integration for starting calls. Teams can self-host it on their own infrastructure at no charge, or choose Hopp Cloud for $15 per user each month with unlimited calls. The app is listed for macOS, Windows, web, and self-hosted use. Hopp lists a support guarantee of less than one day. Its privacy policy says it uses commercially acceptable safeguards but cannot guarantee absolute security.
