Case Study: Onceit improves code quality and troubleshooting with Epsagon

How Onceit is Running their Online Fashion Business Using Modern Applications

Onceit is one of New Zealand’s fastest-growing online fashion retailers, and as it moved to a serverless and microservices architecture on AWS, it needed better end-to-end visibility across complex workflows spanning Lambda, ECS, API Gateway, DynamoDB, RDS, SQS, SNS, and third-party APIs. The company struggled to understand how issues in the application affected the customer experience, conversion, and overall performance.

Epsagon provided Onceit with distributed tracing, architecture visualization, logging, and performance monitoring for both serverless and containerized workloads, with easy onboarding through AWS and Serverless Framework integrations. With Epsagon, Onceit cut troubleshooting time by 90%, reduced error rates by 75%, and improved code and query quality by 40%, while gaining the confidence to optimize costs, spot hidden issues, and scale faster.
