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 Overplane

Overplane is an AI code generation and build system that verifies and safely compiles plain-language specs into working, verified code. Container-sandboxed agents, replayable builds, and multi-agent support. Overplane combines popular AI coding agents with containers, spec-driven development, and formal verification to create a safer and more reliable AI coding workflow. Overplane keeps the speed and fixes the rest in three moves: contain the agent, wrap it in a real build system, and verify the plan before the code exists.
