Ovrin is a compute cloud platform offering isolated Linux sandboxes for AI coding agents. Each sandbox provides a full Linux environment with a filesystem, network stack, process table, and shell, booting in milliseconds. Using gVisor, it intercepts system calls to contain untrusted code. Sandboxes are provisioned on demand and destroyed after tasks complete. The platform includes pre-configured templates for Claude Code, Codex, Gemini CLI, and DeepSeek Harness, ready to use without Dockerfiles. Chrome and Playwright browsers run within the sandbox, enabling agents to interact with web content, scrape data, and capture screenshots. A persistent memory system stores context across instances. Security features include default-deny egress policies, Kubernetes namespace isolation, and scoped API keys. A unified API with Python and TypeScript SDKs supports compute, memory, browsers, secrets, and payments.
