Hopp

Hopp is an open-source remote pair programming tool with low-latency screen sharing and full keyboard and mouse control for every participant. Unlike generic meeting tools, it's purpose-built for developers who need sharp, high-definition streaming.

• One-click collaboration: Launch sessions from your menu bar, with no links to share
• High-definition streaming: Streams in 4K by default, so tiny fonts and syntax highlighting stay readable
• Full workspace sharing: Control any application, from IDEs to design tools
• Multi-participant support: Up to 10 team members in one room for mob programming
• Cross-platform compatibility: Stable on macOS, with Windows support in alpha
• Clear audio: Active noise cancellation keeps voices clean during long sessions

Built on Rust and Tauri for a small system footprint, Hopp offers self-hosting and BYOK (Bring Your Own Keys) for LiveKit, which powers its WebRTC infrastructure. The managed cloud includes a 14-day free trial.

Teams use Hopp for debugging, code reviews, and onboarding, with shared control at sub-100ms latency.
