About
PromptMatrix is an open-source prompt CI/CD pipeline and sub-5ms runtime governance control plane for AI agent swarms (LangGraph, CrewAI, AutoGen, OpenClaw).
Stop hardcoding system instructions into config files or application codebases. PromptMatrix decouples prompt behavioral specifications from code execution—letting teams version, evaluate, approve, and hot-patch prompts without ever redeploying their application.
⚡️ Key Features
⏱️ Zero-Downtime Hot Swaps: Update LLM instructions in real time. Changes propagate in <5ms via edge cache without restarting serverless pods or Docker containers.
⏪ Immutable Version Control: Full Git-like version history with line-by-line diffs and 1-click instant rollbacks.
⚖️ Automated Evaluation Gates: Built-in zero-dependency rule-based evaluations (offline, <5ms) and LLM-as-a-judge quality scoring before merging to production.
🛡️ Enterprise Cryptographic Security: Zero-trust BYOK architecture. AES-256-GCM-encrypted evaluation keys and SHA-256-hashed API keys.
👥 Team Governance: Non-engineers propose prompt tweaks visually; engineers review diffs and approve in 10 seconds.
🔌 Universal Serve API: Clean `GET /pm/serve/{key}` runtime endpoint with dynamic `{{variable}}` interpolation.
