Hire Module Federation experts for your next project
Module Federation lets internal and external teams develop features in isolation, each with its own release cadence. We help you turn this architecture into a secure, scalable platform—so you can move fast without losing control.

Why you should use Module Federation
Module Federation allows teams to build scalable, decoupled frontends—shipped independently across platforms and business domains.
Independent releases
Update parts of your app without waiting for the whole monolith to rebuild or redeploy.

Decoupled teams
Teams can own, ship, and maintain isolated features—without stepping on each other’s toes.

Framework and platform agnostic
Modules can use different technologies or frameworks, and still compose into a single app at runtime—no rewrites or coupling required.

Southern Glazers is using Module Federation on both web and mobile to ship faster
Southern Glazer's Wine & Spirits (SGWS) leveraged Module Federation with Re.Pack and Zephyr Cloud to transform their deployment processes. By splitting their applications into independently deployable modules, SGWS achieved sub-second deployments and rollbacks, which allowed for almost instantaneous updates to compliance fixes and new features.

What should you look out for when adopting Module Federation?
Module Federation can unlock serious scale—but it’s not plug-and-play. From version conflicts to bundle bloat and mobile-specific issues, you’ll want to plan ahead to avoid common integration problems.
Version conflicts
Different remotes can bring different versions of shared packages—leading to inconsistent runtime behavior.
Dependency duplication
Lack of clear sharing strategy can increase bundle size and runtime bugs.
Runtime failures
Remotes can fail to load or behave unexpectedly without proper fallbacks and observability.
Performance overhead
Dynamic loading and fallback logic adds cost—especially without good caching or chunking.
Shared state
Isolating features is easy. Sharing context or state between them isn’t.
Cross-platform integration
Federating between web and mobile brings additional build, runtime, and API challenges.

Use Module Federation in React Native with our open-source library
Re.Pack is an Open Source toolkit that uses Webpack 5 and React Native CLI's plugin system to allow developers to bundle React Native apps using Webpack features.
- First-class support for Webpack and Rspack in React Native
- Support for Module Federation 2
- Drop-in replacement for Metro with minimal configuration
Hire engineers who pioneered Module Federation in React Native
Use Module Federation with React Native
Build mobile apps that download features dynamically at runtime—without needing an app store release. It’s a perfect solution for splitting large apps or decoupling teams.
Build cross-platform federated modules
Design modules once and run them anywhere: mobile, web, or desktop. We will help you create truly platform-agnostic packages ready to be composed into any host.
Build SDKs and infrastructure for third-party developers
Expose your modules to external teams through a lightweight SDK layer. Design interfaces and dev workflows that make it easy for others to build in isolation and ship safely.

FAQs
Implementing Module Federation across platforms can raise questions about tooling, performance, and integration boundaries. Here are some of the most common technical topics we cover with clients building federated frontends.
We can implement federation across web, mobile (including React Native), and desktop apps using compatible tooling and custom adapters.
Yes. We’ve developed and open-sourced tooling that makes federation work in React Native by handling bundling, loading, and native bridges where needed.
Yes, with careful packaging and platform-specific wrappers, we can support federation across platform boundaries.
We implement domain whitelisting, checksum validation, and CI pipelines that validate remote packages before production use.
Absolutely. We can provide a lightweight SDK and development environment to allow external teams to build, test, and deploy in isolation.
