About HeimWall

Signal, not surveillance. See how your engineers use Cursor, Claude Code, and Copilot: catch leaked secrets, PII, and confidential data, without blocking them or reading their prompts. Nothing sits in your send path, your prompt reaches the tool untouched, and what you type into an AI tool is never sent to us. To read your prompt before it is sent, the app reads the composer through the macOS Accessibility API and watches the clipboard. Accessibility is a wide permission and macOS does not offer a narrower one for this.

About Zipbox

Set up Claude Code in the cloud in one click. zipbox boots a disposable sandbox where Anthropic’s agent launches itself at first boot. Your first Tiny box is free. This is Claude Code the way it ships, minus the part where it can touch your laptop. The session on this page is real: write the server, run it, curl it, done. write a tiny node http server that replies "hello from my sandbox", run it, curl it, and show me the output.
