PromptMatrix

PromptMatrix is an open-source prompt CI/CD pipeline prompt management and sub-5ms runtime governance control plane for AI agent swarms (LangGraph, CrewAI, AutoGen, OpenClaw). Instead of hardcoding prompt strings into application code and waiting 20 minutes for CI/CD builds just to tweak an instruction, PromptMatrix decouples prompt behavioral specifications from code execution: ⏱️ Zero-Downtime Hot Swaps: Live prompt updates in <5ms via edge cache. ⏪ Immutable Version Control: Full Git-like version history with line-by-line diffs. ⚖️ Automated Evaluation Gates: Built-in rule-based & LLM-as-a-judge quality checks. 👥 Team Governance: Visual editing for non-engineers with 10-second peer approvals. 🛡️ Zero-Trust Security: AES-256-GCM encrypted keys. 100% open source (MIT) with local-first SQLite and managed cloud.
