Cloud sandbox
thane vs E2B
E2B runs sandboxes in the cloud. thane runs them on your machine with kernel-level isolation.
TL;DR
- E2B charges per sandbox-minute; thane is free for personal use
- E2B sandboxes are remote VMs; thane uses Landlock + seccomp on your local machine
- thane includes a full terminal workspace (split panes, browser, workspaces) — E2B is an API-only service
- thane works offline; E2B requires an internet connection

What E2B does well
E2B pioneered the cloud sandbox concept for AI code execution. Their SDK is clean, their startup times are fast for a cloud product, and the sandbox API is well-designed. If you need to run untrusted code in a throwaway cloud environment at scale, E2B is a serious option.
Where thane differs
thane takes a fundamentally different approach: instead of shipping your code to a remote VM, thane sandboxes it right on your machine using Linux kernel primitives (Landlock for filesystem, seccomp for syscalls). This means zero network latency, no per-minute costs, and your code never leaves your laptop. thane also wraps the sandbox in a full terminal workspace with split panes, an embedded browser, and 41 JSON-RPC methods — so you get both the safety of a sandbox and the productivity of a real development environment.
Which should you choose?
Choose E2B if you’re building a SaaS product that needs to run end-user code in isolated cloud environments at scale. Choose thane if you’re a developer who wants to safely run Claude Code on your own machine without paying per-minute fees, and you want a full-featured terminal workspace to go with it.
