Persistent Docker Workspaces for Coding Agents
1 follower
Your coding agent needs a real filesystem — not a sandbox that forgets everything. Sandock gives it one: long-running Docker containers with SSD-backed persistent volumes and 100% POSIX compatibility. Run Claude Code, Codex, Anthropic Agent SDK, OpenClaw, Hermes, Pi Coding Agent, or your own agents directly — or embed them into your product. Terminal, browser, preview, git, and MCP workflows are built in, with pricing from $5/mo.
Hey PH! 👋
We were building a coding agent on top of Claude Code. It kept failing — not because the code was wrong, but because the sandbox didn't have a real filesystem. Symlinks broken. File permissions wrong. npm install failing silently.
Every VM-based sandbox has this problem: incomplete POSIX support. And every pure sandbox forgets everything when it closes.
We tried the alternatives. One had great DX but cost $150/mo minimum — and still had POSIX issues. Another was powerful but way too complex, clearly built for enterprise teams, not indie builders. Neither solved the actual problem.
We needed something persistent like a VM, fast like a container, POSIX-complete like a real machine, and actually affordable. Nothing existed. So we built it.
What makes Sandock different:
💾 100% POSIX + Persistent SSD Volumes — symlinks, permissions, hard links all work. Claude Code, Codex, Anthropic Agent SDK — zero config, no workarounds.
⚡ Sub-second warm starts, per-second billing — containers stay alive between calls. $5/mo · vs $150+ with alternatives.
🔌 MCP Server Hosting + Simple SDK — 5 lines of Python or Node.js. Persistent MCP servers. No Docker expertise required.
We've been running our own agents on Sandock for months. It's the infrastructure we wished existed when we started.
Your coding agent deserves a real home. What are you building? 🐳
