via “keyboard-and-mouse-input-simulation”

I've been building computer-use tools for a while, and I quietly launched this about a month ago (122 Stars on GH). I figured it was worth sharing here.Over the last few months, a lot of computer-use agents have come out: Codex, Claude Code, CUA, and others. Most of them seem to work roughly li

Unique: Injects input events directly into the OS input queue rather than sending events to specific application windows — ensures compatibility with any application regardless of how it handles input, but requires careful timing and state management

vs others: More universal than application-specific input APIs because it works at the OS level, but requires more careful timing and state management than higher-level automation frameworks that provide built-in synchronization

via “ui element interaction and gesture simulation”

** -  Popular MCP server that enables AI agents to scaffold, build, run and test iOS, macOS, visionOS and watchOS apps or simulators and wired and wireless devices. It has powerful UI-automation capabilities like controlling the simulator, capturing run-time logs, as well as taking screenshots and

Unique: Wraps XCTest's gesture simulation APIs as MCP tools, enabling AI agents to perform realistic user interactions without coordinate calculation or timing guessing — supports accessibility-based targeting for dynamic UIs

vs others: More reliable than coordinate-based automation because it uses accessibility attributes; enables AI agents to interact with dynamic UIs that change layout or position

via “interactive element manipulation (click, type, scroll)”

Native Safari browser automation for AI agents — 80 tools via AppleScript, zero Chrome overhead, keeps logins, runs silently. macOS only.

Unique: Uses AppleScript event simulation for native input handling rather than synthetic DOM events, providing more realistic user interaction that triggers native browser handlers. Includes pre-interaction visibility validation to prevent silent failures.

vs others: More reliable than synthetic DOM events because it uses native OS-level input; better error detection than Puppeteer because it validates element visibility before interaction; less flexible than low-level WebDriver but more user-friendly for typical form automation.
