See the Impact Before You Deploy
LexQ is a rule engine with built-in simulation. Test every rule change against real data, compare versions side-by-side, and deploy only when you're sure.
The Problem
You're changing rules blind
Every rule change is a leap of faith. There's no staging environment for business logic.
No Way to Preview the Impact
You change a pricing threshold or eligibility rule, and find out it's wrong from production incidents — not from testing.
Rules Buried in Code
Business logic scattered across services. Changing one condition means a PR, code review, and full deploy cycle.
Engineering Bottleneck
Every rule change is a dev ticket. Product and ops teams wait weeks for what should take minutes.
if-else Spaghetti That No One Owns
Business logic grows into nested conditionals that nobody wants to touch. Each hotfix adds more branches. Technical debt compounds silently.
Features
Ship rule changes without shipping code
Version-controlled policy management with built-in simulation and instant deployment.
Simulate Before You Deploy
Test rule changes against real execution data before going live. Compare versions side-by-side to see exactly what would change — with zero risk.
A/B Test Rule Versions
Split traffic between rule versions in production. Measure which performs better with real data, then promote the winner with one click.
Git-style Rule Versioning
Draft, review, and publish rules with full version history. Roll back any change instantly. Every edit is tracked with who, when, and why.
Visual Rule Builder
Create and manage complex business rules through an intuitive console. No code required. Conditions, actions, and priorities — all visual.
Instant Deployment Pipeline
Deploy rule changes in seconds, not sprints. Gradual rollout with traffic controls lets you go live with confidence.
Full Execution Traces
Track every rule execution with full audit trails. See which rules fired, which were skipped, and why — all in real-time.
How It Works
From draft to production in minutes
Define Your Rules
Create rule groups through the visual console. Set conditions, actions, priorities, and conflict resolution strategies — no code required.
Simulate & Compare
Run simulations against historical data or custom test cases. See exactly how your rules behave before they touch production.
Deploy with Confidence
Push changes live with one click. Use traffic controls for gradual rollout. Monitor execution in real-time with full audit trails.
