How Cursor built a growth iteration loop on Vercel, unifying four sites with Microfrontends, running experiments with Flags + Edge Config, and shipping faster with an agent-first workflow.

Vercel is a platform for deploying modern web applications with speed and simplicity, offering developers a seamless experience for hosting and scaling their projects. With features like instant deployment, serverless functions, and global CDN, Vercel empowers developers to focus on building great user experiences without worrying about infrastructure management.

Vercel

Cursor unified four separate web properties (marketing site, sign-in dashboard, docs, help center) under a single cursor.com domain using Vercel Microfrontends, routing over 100 paths without downtime. They built an experimentation loop using Vercel Flags SDK, Edge Config, and Statsig to run A/B tests on marketing content, achieving a 5% increase in PLG signups. They also replaced their CMS with an agent-first workflow where AI agents open GitHub PRs, generate Vercel preview deployments, and even produce before/after preview videos — running 200+ agents in parallel to migrate content at a cost of ~$260 in tokens over three days.
