Hashnode, a blogging platform for developers built using Next.js, leverages Vercel to manage custom domains, content at scale, and performance. The company's engineering team saves time by utilizing Vercel's previewing deployments and testing changes in a production-like environment without configuring staging. Migrating to Vercel also improved Hashnode's speed monitoring and optimization, ensuring fast load times and optimized images, which is essential for its developer audience. With Vercel, Hashnode can focus on delivering value to users rather than managing infrastructure.
