“Leveraging Zaraz, Instacart was able to significantly improve performance of our Shopper-specific domains with minimal changes required to the overall site. We had made numerous optimizations to https://shoppers.instacart.com/ but identified third-party tools as the next issue when it came to performance impact. With Zaraz, we optimized third-party load times and using Cloudflare Workers we kept the integration on our own subdomain, keeping control of visibility and security.”
