Stray Toolkit

Stray Toolkit Documentation

Welcome to the Stray toolkit documentation! The Stray toolkit allows you to skip building computer vision models from scratch. Deploy custom detection models in days, not weeks.


The Stray Command Line Tool and Stray Studio can be installed using our install script. We currently support macOS and Linux based systems.

The script installs the tool and Studio into your home directory into a folder called .stray. Some commands are implemented as Docker containers (e.g. calibration, model and studio integrate), which means you will have to have Docker installed and the daemon running.

To install Docker, follow the instructions here.

If you want to use the photogrammetry command, this requires CUDA through Nvidia Docker. To install this, follow the instructions here.

Other commands are implemented as Python scripts and compiled programs. These are installed into the .stray directory.

To install the toolkit run this command in your shell:

curl --proto '=https' --tlsv1.2 -sSf | bash

Then source your environment with source ~/.bashrc or source ~/.zshrc if you are using zsh.

Before using the toolkit, make sure to add STRAY_LICENSE_KEY=<key> as an environment variable. To obtatain the <key>, visit to subscribe or contact us by filling the contact form or via email.

By installing and using the toolkit and our services, you are agreeing to our terms of service.


If you want to uninstall the toolkit, simply delete the .stray directory with rm -rf ~/.stray.
