We\u2019ve open-sourced Brig under Apache 2.0.<p>Brig runs AI coding agents inside a microVM on Mac (Apple Silicon) and Linux (x86_64&#x2F;ARM). It came out of our work on controlled autonomy for production remediation. The same isolation is useful when running coding agents with auto-approval on your own machine.<p>The agent gets its own Linux kernel. You choose the project and credentials to share. The shared project remains writable, and the default network allows internet access.<p>After installation, brig run claude starts Claude Code inside the sandbox.<p>All components are Apache 2.0, including the microVMM, which is under 20,000 lines of code. The README covers installation, the architecture and the security model.","title":"Show HN: Brig \u2013 A MicroVM sandbox for AI coding agents on Mac and Linux","type":"story","url":null}
