What is LexQ?
LexQ is the decision platform for engineering teams. Instead of shipping application code every time a business rule changes, you define decisions in a visual console, prove every change with simulation before production, and deploy without touching application code.Visual Rule Builder
Create conditions and actions through an intuitive UI. Fully visual, fully traceable.
Git-style Versioning
Draft, publish, and deploy rule versions with full audit history.
Pre-deploy Simulation
Test rule changes against real data before they touch production.
Full Execution Traces
Track every execution — what matched, what didn’t, and why.

Architecture Overview
LexQ consists of three main components:| Component | Domain | Purpose |
|---|---|---|
| Console | console.lexq.io | Web-based management interface |
| Engine API | api.lexq.io | Real-time rule execution endpoint |
| Docs | docs.lexq.io | Documentation and API reference |
Who is LexQ for?
LexQ is built for engineering teams that own the business decisions in their systems. Product managers and operations teams work alongside them — defining rules, reviewing simulations, and approving deployments — but engineering owns the integration and operates the platform. Teams use LexQ to:- Update business rules without deploying application code
- Prove every change against real data before it touches production
- A/B test rule versions with production traffic
- Maintain a full audit trail of every change and execution
