Turn your Windows/macOS computer into a scriptable server

Website cntrl.pw
Overview

What it is

Cntrl Bridge turns your Windows or macOS computer into a scriptable server. It runs a lightweight local API that lets you monitor system stats, control media playback, and manage power state from any device on your network. Built with Tauri & Rust.

Intent

I need it when

Build custom IoT-like automation workflows treating a PC as a scriptable device

The product is designed as a lightweight programmable API with React SDK, WebSocket support, and process management capabilities, allowing developers to script their workspace, create custom dashboards, and integrate their PC into automation workflows

Deploy a minimal-footprint system agent that doesn't consume significant resources or clutter the desktop

Cntrl Bridge runs as a tray-only application with ~20MB memory footprint, built in Rust for native performance, and provides zero CPU overhead when idle through lazy-spawned WebSocket loops

Automate power management tasks like shutdown, restart, or sleep from scripts or dashboards

The product exposes power control endpoints (shutdown, restart, sleep, hibernate) through a programmable API, enabling users to trigger these actions remotely via HTTP or WebSocket from custom scripts, dashboards, or automation workflows

Monitor and control PC system resources and performance from remote devices on the local network

Cntrl Bridge provides real-time CPU, memory, disk, and network monitoring via REST and WebSocket APIs, allowing users to access system stats from any device on their local network without installing additional software on client devices

Control media playback and volume across multiple media applications from a single interface

Cntrl Bridge includes media control features that allow users to manage playback and volume across any media app, with real-time updates via WebSocket, enabling centralized media control from remote devices

Drop

Not a fit when

  • User requires encryption for remote access over the public internet, as Cntrl Bridge has no built-in encryption and is designed only for local network use
  • User needs a managed cloud service with vendor support and SLAs, as Cntrl Bridge is a self-hosted local agent in early alpha development
  • User operates on macOS versions older than the minimum supported version or non-Intel/Apple Silicon architectures
  • User requires a graphical UI for all operations, as Cntrl Bridge is tray-only with API-first design
  • User needs production-grade stability, as the product is in v0.x alpha with breaking changes possible without major version increments
