Your AI Stack Is a Black Box

Uncontrolled AI Spend

LLM APIs called without budget limits. Costs spiral with zero accountability per team or project.

Zero Visibility

No one knows what prompts are sent, which models are used, or what data is exposed to third-party APIs.

Security Blind Spots

Prompt injection, data leakage, and jailbreaks slip through with no detection or audit trail.

Everything You Need to Govern AI

< 1ms

Pattern-Based Defense

11 compiled regex patterns detect injection, jailbreak, and data exfiltration attempts in sub-millisecond execution.

NeMo

LLM-Based Guardrails

Colang 2.0 semantic analysis provides deep content understanding. Second-layer defense beyond pattern matching.

Real-time

Cost Governance

Budget limits with 24h spend aggregation. Per-team tracking prevents runaway costs across your organization.

Non-blocking

Async Processing

Celery workers handle LLM calls asynchronously. Gateway returns 202 instantly so your applications never block.

RedisVL

Semantic Cache

Vector similarity prevents duplicate LLM calls. Significant cost savings on semantically equivalent prompts.

Full trace

Audit Trail

Every request logged with cost, tokens, model, latency, and security verdict. Complete observability for compliance.

Enterprise-Grade Architecture

DDD monorepo with 7 packages. Built for resilience.

Domain-Driven Design

Each bounded context is an isolated package with its own domain, application, and infrastructure layers. Clean dependency graph ensures Gateway never touches Agent logic directly. Value objects and domain events enforce business rules at the boundary.

Tech Stack

Modern Python stack with battle-tested components for every layer.

Python 3.12 FastAPI Pydantic v2 LangGraph Celery PostgreSQL Redis RedisVL Docker NeMo Guardrails
Null Fallback Pattern

Every external service has a NullXxxService implementation. If Redis is down, the cache returns a miss. If Celery is offline, tasks run synchronously. Feature flags control activation. The system always responds, even when dependencies fail.

Zero-Regression Protocol

902+ automated tests run per-package to avoid conftest collisions. Every development session ends with a full validation pass. If a passing test now fails, it gets fixed before the session ends. Test baselines tracked across sessions.

One-Command Setup

Full development environment in a single command. PostgreSQL, Redis, and FalkorDB spin up with Docker Compose. UV manages Python dependencies across the monorepo. From clone to running tests in under two minutes.

docker compose up -d make install make test
