kosa8
MicroVM sandboxes for AI agents with checkpoints, forks, a host-side key broker and a hash-chained audit log
kosa8 runs each AI agent's code and tools in its own microVM, on your own machine (macOS, Linux or Windows) or on kosa8 Cloud billed per second. Sandboxes can be rewound to a checkpoint and forked to try ideas side by side. API keys stay in a broker on the host, so the sandbox only ever holds a placeholder, and every action the agent takes goes into a hash-chained audit log.
It targets coding agents, data analysis, evals and RL, and MCP tools. New accounts get $30 of free credit; plans start at $29/month. The software is proprietary.
