Jamstack's shift to edge middleware
Jamund Ferguson, senior engineer at PayPal, on using Jamstack in the enterprise
The important shift was that Jamstack stopped being just a way to ship prebuilt HTML and became a way to bolt dynamic behavior onto a fast static shell. Netlify added serverless functions so a frontend team could keep pages on a CDN but still handle form submits, auth, or API calls. Vercel pushed this further with middleware at the request layer, letting teams rewrite, redirect, and personalize pages before they load, while keeping the core site fast.
-
Netlify functions turned a static deploy into a lightweight full stack app. A developer can drop code into a functions folder, have it deployed as API endpoints automatically, and call it from the frontend without setting up separate servers or provisioning cloud infrastructure.
-
Vercel won mindshare by making these dynamic pieces feel native to the frontend workflow. In practice, API routes sit beside UI components, preview deploys spin up from each Git branch, and middleware runs before a request is served, which makes personalization and routing feel like part of the app, not separate ops work.
-
This is why the category persisted even as the Jamstack label weakened. The durable idea was removing infrastructure toil for frontend teams. Static generation, serverless functions, and edge logic are all pieces of the same model, ship the simple parts as files, add code only where the app actually needs it.
The next phase is less about static versus dynamic and more about where code runs. More request handling will move to edge and middleware layers, so teams can keep the speed of CDN delivered pages while adding localized logic, personalization, and data fetching without rebuilding the old monolithic app stack.
