Bytes issue #382, published April 7, 2025, used “The Great (React) Divide” to describe a dispute over React’s move toward Server Components: the architecture can reduce work sent to the browser, but it also ties application code more closely to frameworks, bundlers, servers, and routing. It was a short, humorous newsletter item—not a controlled performance comparison. React’s documentation offers the clearest way to understand what changes and what does not.
What are React Server Components?
React’s official Server Components documentation defines them as “a new type of Component that renders ahead of time, before bundling, in an environment separate from your client app or SSR server.” Depending on the setup, they can run at build time or for each request on a web server.

The key distinction is where a component executes. Server Components render outside the browser; their component code is not sent to the browser. That can be useful for work such as accessing server-side data or producing UI that does not need browser-side interaction.
What is the difference between Server Components and Client Components?
A Server Component cannot use interactive browser-side React APIs such as useState. When a screen needs interaction, it can combine Server Components with Client Components, which provide the interactive UI in the browser. React explains this distinction in its Server Components documentation.
#1 Best Overall
- Server Components: render in a separate environment, at build time or on a server; their component code is not sent to the browser.
- Client Components: support interactive UI and browser-side behavior.
These are complementary roles, not competing ways to build an entire application. A page can use server-rendered components for parts that do not need browser interaction and client-side components where interaction is required.
Why might a team use Server Components?
Bytes said Server Components can shrink bundle sizes and help optimize time to first paint and interaction. React’s documentation illustrates one reason: a library used only to generate static content may not need to be sent to the browser. The actual benefit depends on the application’s design and what code it would otherwise ship; the newsletter did not report benchmark results, and these benefits are not a guarantee that every RSC application will be faster.
The case for RSC is strongest when a team has useful server-side work to do or wants to avoid sending certain code to clients, while still being able to place interactive behavior in Client Components. A smaller client bundle is one possible outcome, not a performance result that follows automatically from adopting the architecture.
Why are developers upset about React Server Components?
The divide is largely about complexity and control. Bytes described an RSC implementation as involving a capable bundler, a server that can stream the bundle, and a router that can request and process that stream. In practice, building the full experience involves coordination among more parts of the stack than writing components alone.
That coupling can be worthwhile when the application benefits from server-side rendering or reduced client JavaScript. It can be a poor fit for a team whose deployment environment, framework, or existing build setup does not support the required integration well. The issue’s critique should be read as a concern about the architecture’s implementation burden, not as evidence that RSC is inherently bad or that every React app must adopt it.
Do React Server Components need a server?
Not necessarily. React’s documentation says Server Components can run at build time or per request on a web server. A web server is needed for the per-request model, but build-time rendering does not require a server to execute components for each visitor. The right model depends on when the application needs to produce the components and on the framework and deployment environment.
What should a team weigh before adopting RSC?
- Need for server-side work: Consider whether server-side data access or keeping some code out of the browser addresses a real application need.
- Interactive behavior: Identify which UI needs client-side APIs and plan for those parts to be Client Components.
- Framework and bundler support: Check whether the chosen stack provides the streaming, routing, and build integration the application requires.
- Deployment and operations: Match build-time or per-request rendering to the runtime and operational complexity the team can support.
- Integration API stability: React describes Server Components as stable in React 19, but warns that the underlying APIs used by bundlers and frameworks may break between React 19 minor versions. Teams building their own integration should account for that distinction.
These considerations do not establish a universal winner or a workload-specific performance advantage. They help determine whether the benefits justify the additional integration and runtime demands in a particular application.

Bytes mentioned styled-components entering maintenance mode in its April 2025 issue. That is historical context, not a reliable statement of the project’s current status. The project’s documentation, accessed October 7, 2026, describes Server Component support in styled-components v6.3 and later v6 updates; it also shows v7 as alpha. The dated newsletter item and the current documentation are different snapshots, so the former should not be treated as a current project-status report.
