--- title: "What if you wanted to build your own platform for users to generate content? On-demand Builders may be what you‘re looking for!" description: "Architecting a blogging platform on the Jamstack with On-demand Builders" source: "https://www.netlify.com/blog/2021/11/12/architecting-a-blogging-platform-on-the-jamstack-with-on-demand-builders/" last_updated: "2026-08-05T04:39:12.000Z" --- I started a small discussion with the developer experience team here at Netlify, and and transcribed it for those interested and thinking about building larger-scale services. ## The question How would you architect a blogging platform with the Jamstack? A platform where users can: - Log in/Log out - Create blog posts - Publish them on their own URLs to share (like blogplatform.com/cassidoo/mypost) Many people think that this is where server-side rendering rules, and the Jamstack falls short. But behold, Phil Hawksworth had some good things to say! ## Phil’s response 2 parts to this question: ### 1\. Can Jamstack serve user-generated and user-centric content for many users? Yep. [app.netlify.com](https://app.netlify.com/) does this with a statically served app shell, and an API for more than 2 millions users and teams. It’s both dynamic, and personalized. But… blog posts are better not served as JSON which is rendered client-side like the content in the [app.netlify.com](https://app.netlify.com/) example. So, question 2… ### 2\. Can Jamstack deliver rendered content for user-generated and user-centric content? Not at scale until the advent of [On-demand Builders (ODB)](https://docs.netlify.com/configure-builds/on-demand-builders/) and its friends. > On-demand Builders are a type of serverless function that speed up build times for large sites by breaking content into two categories: critical content, which is automatically compiled at build time, and deferred content, which is built upon user request. On-demand builders enables you to incrementally build your site and is designed to work with any framework. Now, it is pretty attractive as an architecture really. It’s like a slight evolution of the [Virtual Lolly](https://github.com/philhawksworth/virtual-lolly) example I have, where we add auth and rendering via ODB. ![Diagram of blog platform site](/v3/img/blog/odbplatformarch.png) With the number of core pages being generated in the build kept to a few hundred (like, the main boilerplate and UI pages, and perhaps the most popular few hundred blog post pages), it could easily be re-deployed with a time period of a few hours so a “fresh” view of the most popular posts and related articles could be pre-generated regularly enough to be fit for purpose. All of the above architecture is viable right now, with the exception of a listing of latest posts per user on a URL like `/{USER}/POSTS`, which would need ODB to support expiring a URL so that it updates when a new post is added. But that view could come from a [serverless function](https://docs.netlify.com/functions/overview/) or [edge handler](https://www.netlify.com/products/#netlify-edge-functions). The blog post pages themselves via ODB are fine. (until we add ability to modify published posts, at which point the same logic as above applies). ## Thanks, Phil! Now what? Whew!
