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 NeoBox

A native macOS Neo Geo emulator with built-in Geolith, CRT shaders, save states, gamepad hot-swap, and per-game memory cards. No setup. Just play. Xbox, PS, Switch Pro, and MFi controllers work over USB or Bluetooth with zero configuration. Each shot is the 304×224 native frame, with the CRT shader baked in if you've got it on. The sidebar is always one click away from the next game. Every choice has a sensible default, the preferences pane is for when you want the arcade feel of a CRT, or when a particular cart needs MVS mode.
