“The market is dominated by sandboxes that rely on OS-isolation or language-specific isolation [ 2 , 5 , 33 – 36 ] . Others use hardware-virtualized microVMs, but they are SaaS products with no local deployment [ 7 , 13 ] ; are not open-source [ 22 ] ; are general VM runtimes rather than purpose-built agent sandboxes [ 37 – 39 ] ; focus primarily on computer use [ 17 ] ; or target mainly programmable SDK agents or MCP gateways rather than terminal-based coding agents [ 14 , 20 ] .”
