PemPem, a mobile-based trading platform for smallholder farmers, was experiencing rapid growth and scaling issues with its previous solution. They transitioned to WunderGraph Cosmo's GraphQL Federation solution, which allowed them to serve multiple endpoints without restrictions with a single router, alleviating concerns about client permissions and scalability. The Cosmo Router provided end-to-end observability across various data sources, enabling the team to understand usage patterns and improve development time for endpoints. With Cosmo Studio, they gained detailed analytics dashboards and advanced request tracing, allowing them to identify bottlenecks and maintain productivity. The migration process was smooth, with setup completed within a day and full production integration in under 30 days. WunderGraph Support provided timely assistance during the transition, making it an enjoyable experience for both parties.
