With Workers, developers can build agents that sync CRM data on a schedule, open issues when error rates spike, and turn Slack threads into formatted content. Under the hood, every Worker runs on Vercel Sandbox. The problem: safely running code from any developer or agent Notion wanted to let anyone extend their platform with custom code. That's a hard infrastructure problem, but an even bigger security problem. Every Notion Worker runs arbitrary code generated by a third-party developer or agent, on behalf of a Notion user, potentially inside an enterprise workspace. Without proper isolation, a Worker would run in the same environment as the Custom Agent, with access to its secrets, permissions, and everything else in that execution context. A single prompt injection could exfiltrate credentials or access another user's data. The requirements were clea Karson Seeley, Harpreet Arora ](/customers/notion-workers-vercel-sandbox) - [ 3 AugustCustomers ## How Factory scaled its cloud backend to one billion monthly requests on Vercel Factory on Vercel One billion backend API requests served daily 350ms p95 response time Scaled backend, internal tooling, and security without a dedicated infrastructure team Factory's mission is to bring autonomy to every phase of the software development lifecycle, from signals to production. Not to replace engineering judgment, but to automate the repetitive work around it, giving engineers more time to focus on the decisions that matter most. To deliver this enterprise-grade platform, Factory adopted their ideal operation model internally: remaining lean and agile by deploying Droids to manage routine workloads, so their engineers could focus strictly on building the product. As Factory scaled from a simple web app into a multi-surface platform, serving everyone from individual developers to enterprises with tens of thousands of engineers, their backend scaled alongside them. Today, a single Next.js backend on Vercel powers every surface, handling one billion daily requests across Susan Aziz, Ben Sabic ](/customers/how-factory-scaled-its-cloud-backend-to-one-billion-monthly-requests-on-vercel) - [ 1 MayCustomers ## How GitBook serves 30,000 sites with sub-second content updates GitBook on Vercel 30,000 documentation sites hosted on a single Vercel deployment 120 million monthly page views served from the edge 40,000 cache invalidations processed daily, each resolved in under 300ms 41% of all traffic now comes from AI crawlers and automated systems GitBook hosts 30,000 documentation sites on Vercel, serving 120 million page views every month. Companies like n8n, Nvidia, and Zoom trust the platform to keep their docs fast and current. For modern engineering teams and coding agents, documentation is as critical as the production code it describes, and GitBook sits at the center of that expectation. GitBook's publishing model mirrors how teams ship software: propose changes, review, and merge. With 30,000 independently managed sites each on its own update cadence, keeping content fast and fresh was a complicated engineering problem. Before migrating to Vercel, site editors would hit merge, visit the published site to validate, and see old version of the content.
