Is JAMstack still relevant in 2026?
Yes. The ideas live on in modern frameworks like Next.js static generation and edge delivery. The term is less buzzy, but pre-rendered, API-driven sites remain fast and cheap to run.
What are the benefits of JAMstack?
Speed from CDN delivery, strong security with no server runtime to attack, easy scaling, and lower hosting costs for content-heavy sites.
Is JAMstack good for eCommerce?
Yes, for storefronts. JAMstack teams pair a fast static front end with commerce, payments, and inventory delivered through APIs.
Does Udaan build JAMstack or modern front-end sites?
Yes. We build fast, SEO-friendly, and API-driven sites, typically with Next.js and a modern static-generation approach.
When is JAMstack a bad fit?
Avoid it if you need heavy real-time personalization server side or a large amount of constantly changing server-rendered logic on every request.
