Architecture Built for Production AI
A complete infrastructure stack — from visual builder to agent runtime to data layer. Every component purpose-built, vertically integrated, and production-hardened.
Four Layers. One Stack.
OrchStack is a vertically-integrated platform — every layer is purpose-built to work together, from the UI down to the database.
Application Layer
Agent Runtime
Orchestration Engine
Infrastructure
Deep-Dive into Every Service
Six battle-tested services power every agent execution. Each is independently scalable, fully observable, and configurable per tenant.
LLM Router
Intelligent multi-provider routing with automatic failover, latency-aware selection, and real-time cost optimization across OpenAI, Anthropic, Google, and self-hosted models.
Memory Manager
5-tier memory architecture — session, long-term, entity, shared, and collective — backed by Redis for hot data, PostgreSQL for persistence, and Vector DB for semantic recall.
Tool Executor
Sandboxed, permission-scoped tool execution with configurable retry logic, timeout handling, circuit breakers, and full execution tracing for every tool call.
Knowledge Engine
Production-grade RAG pipeline with hybrid search (BM25 + semantic), multi-stage re-ranking, chunk optimization, and source attribution on every retrieval.
Guard System
Input/output validation layer with PII detection, content policy enforcement, prompt injection defense, token budgets, and per-tenant cost limits — all configurable per agent.
Event Bus
Real-time event streaming for every agent action — SSE for live UIs, webhook delivery with retry, and append-only audit logging for compliance and debugging.
How a Request Flows Through OrchStack
Every agent request follows a deterministic pipeline with full tracing from ingestion to outcome measurement.
Security by Design
Every layer of OrchStack is built with enterprise security primitives. Not bolted on — baked in.
Multi-Tenant Isolation
Row-level security (RLS) on PostgreSQL ensures tenant data is fully isolated at the database level. No shared state leaks between organizations.
Encryption at Rest + Transit
AES-256 encryption for data at rest, TLS 1.3 for data in transit. Secrets are stored in vault-backed key management with automatic rotation.
SOC 2 Compliance Ready
Architecture designed for SOC 2 Type II compliance with access controls, change management, and continuous monitoring built into every layer.
Immutable Audit Trails
Every agent action, tool call, LLM request, and admin change is logged to an append-only audit log with cryptographic integrity verification.
Built With Modern Infrastructure
Proven, open-source technologies — chosen for reliability, performance, and developer experience.
