Sandock
Persistent Docker Workspaces for Coding Agents
Sandock provides coding agents with a robust, persistent execution environment, moving beyond temporary sandboxes. Key features include:
* Long-running Docker containers
* SSD-backed persistent volumes
* 100% POSIX compatibility
* Kernel-level isolation and resource limits
* Built-in terminal, browser, Git, and MCP workflows
This platform enables direct execution or embedding of various coding agents, such as Claude Code, Codex, Anthropic Agent SDK, OpenClaw, Hermes, and Pi Coding Agent. It ensures agents have a real filesystem, unlike ephemeral sandboxes that reset after each operation, allowing for complex, multi-step tasks and the storage of generated files or intermediate outputs. The secure container-level isolation prevents environment conflicts and offers configurable CPU, memory, and storage limits.
Sandock is an ideal solution for developers, engineering teams, and product innovators who require reliable, secure, and persistent environments for their coding agents. It supports multi-language execution (JavaScript, TypeScript, Python, shell) with real-time output streaming. With an SDK-first API, fast startup times, and usage monitoring, it streamlines development and deployment, offering an efficient and cost-effective alternative to VM-based solutions.
