Sandboxes in Dockerfor Coding Agents
Run Claude Code, Anthropic Agent SDK, MCP Servers, OpenAI Codex, and more in cloud sandboxes — with persistent volumes for 100% POSIX compatibility. 1/10 the cost of VM-based alternatives.
Docker Containers vs VM-Based Sandboxes
Why coding agents like Claude Code fail on other sandboxes — and work perfectly on Sandock
VM-Based Sandboxes (E2B, Daytona...)
- ·Slow cold starts (30-60 seconds per VM)
- ·Expensive — $150+/month minimum
- ·Incomplete POSIX support breaks coding agents
- ·No persistent volumes — data lost on restart
- ·Claude Code, Codex often fail due to filesystem gaps
With Sandock
- 3-second cold starts with Docker containers
- 1/10 the cost — from $0.005/hour
- 100% POSIX-compatible persistent volumes
- Claude Code, Agent SDK, Codex all run flawlessly
- Full filesystem — coding agents just work
