It uses Yukariin's (based on AUTOMATIC1111's code) and Moffatman's "black spot" model update and implementation for solving 4chan's captchas.
You can easily host it now with the Dockerfile or just use systemd file after installing the dependencies from requirements.txt in a venv. If you use Chana, you can use your own server for captcha solving instead of default one (see in settings tab).
