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 Open Envelope

The full technical specification for the Envelope team definition format, agent structure, workspace documents, adapters, variables, secrets, and access policies., VS Code, JetBrains, and any SchemaStore-aware editor will validate *.envelope.json files automatically, no configuration needed. The Envelope team definition, the structure that describes agents, roles, hierarchy, escalation paths, required secrets, and adapters, is published as a formal, versioned open source specification. Anyone can read it, validate against it, and build tooling around it.
