• Spring Boot 3.4.1 (platform-backend-core), 3.5.7 (platform-ai-core)
• Java 17 (core), Java 21 (platform-ai)
• PostgreSQL — platform_backend schema (core data), platform_ai schema (RAG, isolated)
• pgvector — Vector extension for embeddings; HNSW index
• Flyway — Database migrations

Discovery Agent

• Spring Boot 3.4.1, Java 17 — Lightweight, stateless
• Kubernetes Java Client — Service discovery
• Helm — Deployment in customer clusters

Deployment

• Railway — platform-backend-core, platform-ai-core
• Vercel — api-management-ui, api-govern-os

Rationale

• Next.js — Full-stack React, strong ecosystem, Vercel deployment
• Spring Boot — Enterprise-grade, rich ecosystem, JPA/Flyway
• PostgreSQL + pgvector — Single DB for relational + vector; avoids managed vector store cost
• Clerk — Org-based auth out of the box; custom ABAC for AuthZ
