Supported platforms
Reflex is one app for macOS, Windows and Linux. Each platform has its own way of letting software read and operate other apps, so the level of testing differs. This page is kept honest: “verified” means tested on a real machine for this release.

Browsers
Chrome, Edge and Brave (with the Reflex extension, or through accessibility). Safari and Firefox work through accessibility.
Requirements
- 8 GB RAM minimum; 16 GB recommended when using Qwen3-4B.
- About 4 GB free disk space with both local models.
- A GPU is optional — Reflex uses Metal, CUDA or Vulkan when available and runs on the CPU otherwise.
Known limits
- Apps that draw their own interface without accessibility information (some games, remote desktops, canvas-based apps) can't be operated directly; Reflex points at the target and asks you to click, and can use cloud vision (Pro) to read them.
- Linux Wayland sessions restrict some window information; X11 gives the best results.
