Case Study: Mercado Libre achieves near-zero errors, sub-50ms response times, and 20% infrastructure cost savings with New Relic

Mercado Libre increases conversion rate by improving user experience

MercadoLibre, the largest e‑commerce ecosystem in Latin America serving over 550 million people across 13 countries, was rapidly scaling from a monolithic platform to decentralized teams and hundreds of deployments per week. That growth created challenges with scalability, performance, downtime, and limited visibility into application errors and conversion-impacting issues, particularly for critical services like MercadoPago.

By deploying New Relic APM, Browser, and Insights companywide, MercadoLibre gained real‑time software analytics that pinpointed errors, prioritized issues affecting conversions, and improved testing and integrations. The result: error rates dropped to zero in key areas, response times fell to under 50 ms, conversion rates rose, and infrastructure costs were reduced (about 20% fewer virtual machines), delivering better customer experience and operational efficiency.
