Show HN: Drop – a rootless Linux sandbox with gVisor support

Drop is a rootless Linux sandbox tool that isolates programs and coding agents without requiring containers or root access, using your existing system distribution. It features disposable environments similar to Python's virtualenv, flexible TOML configuration, and optional gVisor integration for additional kernel-level isolation. The tool is designed to contain damage from malicious or compromised software while maintaining easy access to already-installed programs.
