For developers needing to run Claude Code with full freedom without worrying about its impact on their system, the claude-docker tool offers a smart solution: running Claude in a sandboxed Docker environment with just one command. This means you can fully explore Claude's capabilities within a safe, isolated space.
Hey WondTech readers! Today we've got fantastic news for every developer working with Claude Code who needs a secure environment for experimentation. Have you ever wanted to run Claude Code with full permissions, but worried it might touch or change something outside your project? Well, we have the perfect solution for you: a new tool called claude-docker. What does this mean for you? Simply put, this tool allows you to run Claude Code with complete freedom inside a totally isolated Docker container. Imagine having a sandbox where you can do anything you want without it affecting the rest of your house (your system). That's exactly what claude-docker provides. You can now explore all of Claude's capabilities, grant it full permissions to operate, all while your main system remains protected. The coolest part is that the installation is just one line! Yes, a single command-line script builds a super minimal Docker image (node:22-slim), pre-installing Claude Code and the RTK CLI. Afterward, you'll have two new commands: claude-docker, which launches Claude inside the container and mounts your current directory into it, and claude-docker-sh, which drops you directly into a bash shell within the same container, perfect for exploring or debugging. The big advantage here is security. When Claude Code refers to «dangerously skip permissions,» it's natural to feel a bit uneasy. But with claude-docker, this permission skipping becomes incredibly safe because it happens within the isolated container. Claude can act completely freely, but it's confined to the container's filesystem plus whatever directories you've explicitly mounted. It even runs as a dedicated non-root «claudeuser» for added security. There are no separate binaries or system PATH changes involved. All the install script does is append these commands as aliases to your shell's rc file (whether bash or zsh). The only requirement is that you have Docker already installed and running. Simply run the appropriate curl command for your shell, or review the script first if you prefer, and you'll be ready to go. It's a straightforward, secure, and powerful solution for developers who value both freedom and protection.
