A cloud-based service that provides isolated, ephemeral virtual machines for developers and security researchers to safely execute and test untrusted code, scripts, or applications. Inspired by the “Show HN: Katakate – Dozens of VMs per node for safe code exec” and the need for secure environments to test code without risking compromise, as highlighted by the AWS account breach and nuclear plant hack news. SecureVM Sandbox offers a pay-as-you-go model for isolated execution environments, preventing “brain rot” in LLMs by providing a safe sandbox for their output, and offering a cost-effective alternative to managing complex local testing setups or expensive cloud services.
