AutoFyn is an autonomous coding agent that takes a GitHub repository and task prompt, then generates a pull request through planning, building, reviewing, and committing in sandboxed environments.

Users set a time limit from 30 minutes to over 8 hours, with code execution isolated from the host machine; optional Docker access requires explicit enabling. Installation involves cloning the repo, running install.sh, and using CLI commands like "autofyn run new -p 'task' -d duration" for runs, monitored via dashboard at localhost:3400 or CLI.
