About Build A Harness

Aielia is an open-source, self-hosted AI assistant that runs an 11-layer harness every turn and stops for your approval before sending email, paying, or running commands. Plus a visual builder that compiles to LangGraph, CrewAI, Mastra, or MS Agent Framework. Meet Aielia, she answers a quick question in one step, and stops for your approval before she sends an email, pays an invoice, or runs a command. A harness is the governance and reliability control plane around an autonomous agent, the agent proposes, the harness decides what happens next.

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.
