Welcome to ControlR

ControlR is an open-source remote control and remote access server. A web dashboard and a set of self-hosted agents let you connect to Windows, macOS, and Linux machines, then stream screens, run a PowerShell terminal, transfer files, and chat with the desktop user.

Why ControlR?​

  • Cross-platform: Web dashboard works in any modern browser; agents run on Windows, macOS, and Linux.
  • Real-time control: WebSocket screen streaming and input forwarding, backed by a SignalR control plane.
  • Multi-tenant: Server, tenant, and per-user isolation. Access is decided by permission assignments rather than fixed roles, and each assignment is scoped to a level such as a tenant, a customer, a device group, or a single device.
  • Self-hosted: Run the whole stack in Docker or as a native process on Linux. Your data stays on your hardware.
  • MIT licensed: Source available, no per-agent or per-seat fees.
  • Getting Started: Components, prerequisites, and architecture overview.
  • Installation: Docker Compose quick start and agent install scripts.
  • User Guide: Dashboard, device access, deploy, and admin pages.
  • Architecture: How the server, hubs, and agent fit together.
  • API Reference: REST endpoints, SignalR hubs, and NuGet clients.
  • GitHub: Source code, issues, and discussions.
  • Discord: Community chat.
