Isolarium is a new open-source command-line tool that provides three flavors of secure, isolated sandboxes for running GenAI-based coding agents like Claude Code. The three isolation modes are: Nono (lightweight, least secure), Container (moderate overhead, shares only the working tree), and Virtual Machine (slowest but strongest isolation, supports Testcontainers). The motivation is to protect developer workstations from risks including credential exfiltration, malicious command execution, and unintended damage caused by coding agents. Isolarium integrates with the author's 'Idea to Code' workflow via the `isolarium implement` command.
