Prompt Matrix - Showcase Project

PromptMatrix is an open-source prompt CI/CD pipeline and sub-5ms runtime governance control plane for AI agent swarms (LangGraph, CrewAI, AutoGen, OpenClaw). Instead of hardcoding prompt strings inside application repositories and waiting 20 minutes for CI/CD builds and Docker redeploys just to change an instruction, PromptMatrix decouples prompt behavioral specifications from execution logic. Key Capabilities: • ⏱️ Zero-Downtime Hot Swaps: Update prompt instructions in real time with sub-5ms edge cache delivery. • ⏪ Immutable Version Control: Full Git-like version history with line-by-line diffs and 1-click rollbacks. • ⚖️ Automated Evaluation Gates: Built-in rule-based checks (<5ms offline) and LLM-as-a-judge scoring before merging to production. • 🛡️ Zero-Trust Security: AES-256-GCM encryption for evaluation keys and SHA-256 hashed API keys. • 👥 Team Governance: Non-engineers propose prompt edits visually; engineers review diffs and approve in 10 seconds. • 🔌 Universal Serve API: Low-latency GET /pm/serve/{key} endpoint with dynamic {{variable}} interpolation. Storage & Deployment: • Local-First (OSS): Runs locally on SQLite with zero external dependencies (MIT Licensed). • Self-Hosted Team: Connects seamlessly to PostgreSQL. • Managed Cloud: Multi-tenant cloud control plane with automated eval gating, Slack bots, and GitHub Actions integration.
