HardwareDiffers

Not documented; needs Python 3.12 and Chrome or Chromium; a local model needs your own GPU

For local models, a GPU that can run a 14B model (Magistral, Qwen, DeepSeek); with a cloud API, no GPU needed

Any machine running Chrome or Edge with a cloud model; local models work best for simple tasks and need a 16k+ context

Windows, macOS and Linux (install steps cover each)

Windows, macOS and Linux with Docker Desktop or Docker Engine

Any desktop OS with Chrome or Edge; Firefox and Safari not supported

Setup effortDiffers

Medium; clone, install Python deps with uv or conda, edit config.toml with model keys

Medium; Python 3.10, Docker Compose services (SearxNG, Redis), a local model server and .env config
