DesktopCtl

Local CLI for AI agents to observe and control your computer via screen, mouse, and keyboard. Bring your own AI - any model, even without vision.

Runs fully local. No screenshots sent to the cloud.

Why DesktopCtl

• Local-first runtime. No cloud dependency
• Bring your own AI: works with any desktop AI agent
• GPU-accelerated text recognition and computer vision
• Selector-first automation (--text, --token) with coordinate fallback
• Agent-friendly explicit waits and post-action verification
• Stable JSON contracts for agent integrations

Architecture

DesktopCtl is split into two binaries:

• DesktopCtl.app (desktopctld): daemon that owns perception, state, execution, and verification
• desktopctl: stateless CLI surface for actions and queries over local IPC

Repository layout:

• src/desktop/core - shared protocol and types
• src/desktop/daemon - daemon runtime
• src/desktop/cli - CLI client

Current Scope

• macOS-first
• OCR-first perception pipeline
• Tokenized screen output for agent grounding
• Deterministic CLI primitives for click/type/wait flows

Prerequisites

• macOS (current support target)
• Rust toolchain (cargo)
• just command runner
• Accessibility permission for DesktopCtl.app
• Screen Recording permission for DesktopCtl.app

Quick Start

make install

raw="$(desktopctl app open Notes --json)"
win_id="$(printf '%s' "$raw" | jq -r '.result.window_id // empty')"
desktopctl keyboard press cmd+f --active-window "$win_id" --no-observe
desktopctl keyboard type "Shopping list" --active-window "$win_id" --no-observe
desktopctl screen tokenize --active-window "$win_id"

Status / Roadmap

• Status: active development, with macOS-first CLI and daemon workflows already usable.
• Reliability for text/token-driven actions and verification loops. Stable machine-readable error codes.
• Upcoming CLI: doctor, richer window/app introspection, and --explain failure output.
• Better local computer vision and semantic UI tokenization.
• Multi-platform support.
