How we built a platform for 1,000 developers at WIX

WIX’s internal development platform, Nile, streamlines microservice development for 1,500 engineers by abstracting away recurring infrastructure concerns. By shifting from traditional libraries and frameworks to a unified platform, the organization successfully reduced boilerplate code—such as authentication, input validation, and PII management—by 90%. The platform’s success relies on three core principles: maintaining "boots on the ground" through close collaboration with product engineers, "paving the road" to standardize common development paths, and treating trust as a currency to drive adoption. With 4,000 microservices and 600 daily deployments, Nile enables developers to focus on business logic rather than infrastructure. The platform team prioritizes user-centric design, utilizing an advisory board and direct pair programming to ensure the system addresses real-world pain points while maintaining high velocity across global development sites.
