Container sandbox
thane vs Docker Sandboxes
Docker gives you containers. thane gives you kernel-level sandboxing without the overhead.
TL;DR
- Docker requires a daemon, images, and container orchestration; thane sandboxes launch instantly
- thane uses Landlock + seccomp for file/syscall restrictions — no container overhead
- Docker sandboxes live in separate filesystems; thane sandboxes share your real filesystem with per-path restrictions
- thane includes a terminal workspace; Docker is infrastructure-only

What Docker Sandboxes does well
Docker is the industry standard for containerization. It has massive ecosystem support, battle-tested isolation, and works on every platform. For production deployments and CI/CD pipelines, Docker’s container model is proven and well-understood. The tooling ecosystem (Compose, Swarm, Kubernetes integration) is unmatched.
Where thane differs
For local Claude Code sandboxing, Docker is overkill. You need to build images, manage a daemon, deal with volume mounts, and navigate container networking — just to restrict what Claude Code can do on your machine. thane’s Landlock + seccomp approach applies restrictions directly to processes without any of that overhead. Claude Code runs in your real filesystem with per-path read/write/deny rules, starts instantly, and doesn’t need a container runtime. Plus, thane wraps it all in a productive workspace with split panes, an embedded browser, and a 41-method JSON-RPC API.
Which should you choose?
Choose Docker if you need reproducible production environments, CI/CD isolation, or cross-platform container support. Choose thane if you want lightweight, instant sandboxing for Claude Code on your Linux machine with a developer-first terminal workspace.
