Microfrontends promise to break down large, complex applications into independently deployable units-unlocking team autonomy, faster releases, and scalable architectures. On paper, they sound like the natural next step after microservices. In practice, however, the reality is more nuanced.

This talk shares hard-earned lessons from adopting microfrontends in production at scale. We’ll walk through what worked well, where hidden complexity appeared, and the trade-offs teams rarely talk about before diving in. Topics include:

- When microfrontends shine: organizational scaling, parallel development, domain-driven boundaries.
- Where they hurt: runtime overhead, inconsistent user experience, duplicated dependencies, and infra bloat.
- Architectural patterns in the wild: iframe isolation, build-time composition, runtime composition with Module Federation, and hybrid approaches.
- Cross-cutting concerns: auth, routing, design systems, and performance budgets—how small mistakes here multiply quickly.
- What we’d do differently: practical guardrails, governance models, and tooling choices that helped (or failed).

Attendees will walk away with a playbook of do’s and don’ts: how to decide if microfrontends are right for your org, how to adopt incrementally without overwhelming infra or developers, and how to avoid the most common pitfalls.

Whether you’re considering microfrontends for the first time, actively migrating, or living with the consequences, this session will help you see beyond the hype and make grounded architectural decisions.
