PromptMatrix

What is PromptMatrix?

PromptMatrix is a governed control plane for LLM prompts, agent personas, and tool schemas. It helps teams move prompt changes out of source code and into a versioned registry with approval workflows, visual diffs, audit logs, and instant rollout. Non-engineers can propose edits in plain text, while engineers review and approve before anything goes live. Changes update runtime behavior without redeploying the app, and every version is stored for rollback and compliance. It supports browser storage, SQLite, and self-hosted setups, so teams can start local and scale up later without lock-in. The product is built for multi-agent systems and works with frameworks like LangGraph, CrewAI, and OpenClaw.
