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 Mocktail

Self-hosted mock API server + dashboard in one ~25 MB binary. Define endpoints, generate realistic data, test errors and latency, and inspect live traffic. Model the responses your app expects, headers, delays, even the flaky 401, and let Mocktail keep the data lively. Keep responses fixed, generate fresh values on every request ( uuid, email, price, name ), or swap real fields for fake data when you need to anonymize a response. Create an endpoint, hit Test right from the dashboard, and watch it land in the live stream, method, status, latency, and the exact response and headers served.
