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 Mail client optimized for self

A self-hosted webmail client for people who run a lot of addresses across a lot of domains. One list, one keyboard, one container. The script generates its own secrets, brings up Postgres and the app, and prints the address to open. Full instructions, environment variables and an upgrade path are in the README.
