While I strive for accuracy, frontend technologies evolve rapidly. Always validate against current documentation when making critical decisions for your organization. I take no responsibility for decisions made based on this information.
Introduction
In today’s digital landscape, the rendering strategy you select for your web frontend is a critical architectural decision with far-reaching consequences. It fundamentally shapes your frontend’s performance profile, SEO effectiveness, development complexity, and infrastructure requirements—all of which directly impact both user experience and business outcomes.
This strategic decision has become increasingly complex as the frontend ecosystem has evolved from simple client-server models to a rich spectrum of hybrid approaches. Many organizations struggle with this decision, often defaulting to whatever their chosen framework provides rather than making an intentional choice aligned with their specific business requirements.
This guide equips technology leaders and decision-makers with:
- A clear comparison of traditional and emerging rendering strategies with their respective trade-offs
- A structured decision framework for selecting the optimal approach based on your specific context
- A comprehensive capability matrix of modern frameworks to inform technology selection
- Practical guidance on implementation considerations, including CMS integration
Rather than advocating for a single “best” approach, this guide aims to provide you with the strategic context and technical understanding to make informed decisions that align with your organization’s specific requirements, constraints, and business objectives.
Key Performance Metrics and Terminology
Before diving into rendering strategies, it’s essential to establish a shared vocabulary of the key metrics and concepts that inform architectural decisions:
Core Web Vitals
- LCP (Largest Contentful Paint): Measures loading performance—how quickly the largest content element becomes visible
- FID (First Input Delay): Measures interactivity—how quickly the page responds to user interactions
- CLS (Cumulative Layout Shift): Measures visual stability—how much unexpected layout shift occurs during page loading
Additional Performance Metrics
- FCP (First Contentful Paint): The time until the first content element is rendered—a critical user perception metric
- TTI (Time to Interactive): When the page becomes fully interactive and reliably responds to user input
- TTFB (Time to First Byte): Server response time—affects all subsequent rendering processes
- TBT (Total Blocking Time): The total time the main thread is blocked, preventing user interactions
Key Technical Concepts
- Hydration: The process of attaching JavaScript event listeners to server-rendered HTML to make it interactive
- Resumability: A newer approach that avoids hydration by serializing the application state
- Bundle Size: The total JavaScript payload that must be downloaded, parsed, and executed
- Code Splitting: Breaking JavaScript bundles into smaller chunks loaded on demand
- Progressive Enhancement: Building frontends that work without JavaScript, then enhancing with interactive features

Content Management System (CMS) Compatibility Matrix
The choice of rendering strategy is deeply intertwined with your content management approach. Different CMS architectures enable or constrain your rendering options in significant ways.
CMS Architecture Overview
Content Management Systems broadly fall into four categories, each with distinct implications for your rendering strategy:
-
Traditional Coupled CMS: Systems like WordPress and Drupal combine content management and delivery, typically favoring server-side rendering but limiting frontend flexibility.
-
Headless API-first CMS: Platforms like Contentful and Sanity separate content from presentation via APIs, supporting all rendering strategies and offering maximum frontend flexibility.
-
Git-based CMS: Solutions like Decap CMS and TinaCMS store content in Git repositories alongside code, excelling at static generation but less suitable for frequently updated content.
-
Hybrid CMS: Systems like Storyblok and Prismic offer flexible delivery options, balancing traditional CMS convenience with headless architecture benefits.
-
No CMS: Content is managed within the same repository as the codebase. This approach is very common for web applications and small sites.
