Everything you need to test optimistic concurrency control

Chaos Injection

Inject latency, spawn concurrent transactions, trigger 40001 conflicts on demand

Live Telemetry

Watch conflicts happen in real-time with SSE-powered metrics and visualizations

Backoff Analysis

Validate retry patterns and detect retry storms before they crash production

AI Assistant

Design transactions via natural language and get smart conflict-prevention tips

Visual Transaction Builder

Design flows.
Generate code.

Drag and drop operations, connect transaction flows, and automatically generate production-ready code with proper retry logic.

Aurora DSQL

Optimistic Concurrency Control

SQLSTATE 40001

Aurora DSQL uses commit-time adjudication. Conflicts throw 40001 - we help you handle them gracefully.

Multi-Region Active-Active

Test cross-region latency scenarios and validate transaction resilience across regions.

UUID vs Serial Keys

Visualize write distribution and see how sequential keys create hotspots.

Exponential Backoff

Validate your retry patterns use proper backoff to prevent retry storms.

Ship with
Confidence

Stop guessing how your code behaves under concurrent load.
Test distributed transactions before production.
