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 Spanly

Observability for Model Context Protocol (MCP) servers. Built for SaaS engineering teams shipping MCP in production, alongside the Datadog, Sentry, or New Relic you already run. That's how it can tell you a tool name is why agents pick the wrong tool, or a schema is why they pass bad arguments, not just that p95 moved. Health monitors connect to your MCP servers on a schedule, list their tools, prompts and resources, and alert your channels when a server goes down.
