We’re in the early stages of planning a large, enterprise-level fintech application. The current architecture roadmap involves 10+ separate modules that will be developed and maintained by different teams over time.

We are considering Module Federation to enable independent deployment, clear separation of concerns, and parallel development. However, the application will also require Server-Side Rendering (SSR) for SEO, performance, and better initial load times.

I’m trying to evaluate whether Next.js or Remix (or any other framework you’ve had success with) would be a better fit for this architecture in the long run, especially in terms of:

Maintainability for a large codebase with many teamsSSR compatibility and performance with Module FederationDeveloper experience and tooling supportLong-term scalability and upgrade pathAny pitfalls or lessons learned from real-world implementations

If you’ve worked on large distributed frontends or have implemented Module Federation with SSR, I’d love to hear your thoughts, recommendations.
