Microfrontends are an architectural pattern where a web application's frontend is broken down into smaller, independent, and self-contained modules, similar to how [microservices](https://www.google.com/search?sca_esv=9901191787690ede&sxsrf=AE3TifOKBZnwTNORE9pKbCkRDi-kwl_Xrg%3A1763745778743&q=microservices&sa=X&sqi=2&ved=2ahUKEwjN1_aE4YORAxUNT2wGHYrrATIQxccNegQIIhAC&mstk=AUtExfB3TLDBKu6LumnPrijZT96G2FuCILHuSSO6mV8CNVXfEi71f4o_PW0Kwoo73FppwTODKC5VVUBJOSCm9lMbxCjJnPV7N_MmYTa3MiCcmzevNZR14jURb0yOfBzaLoa1FTrPVg8FxijwP-GonSxmm3wJHJURYTqLFnTNO1DqLBqRDgVU3rpnY6w8FRRk_ttMvYAU728ZheIiSOVAddivBAct5wQ7uX3jFtAOEDNWZYFgXp5JpQRK4ODkQplv66lJhuYFFUrV85DuazTs2ipARbx2&csui=3) work on the backend. Each module can be developed, tested, and deployed independently by different teams, often using different technologies, to build a single, seamless user interface. This approach enhances scalability, flexibility, and the ability for teams to work more autonomously.

**Independent modules**:

The UI is split into smaller, manageable parts, like a product listing, shopping cart, or user profile, each responsible for its own functionality.

**Independent development**:

Different teams can work on different microfrontends simultaneously without blocking each other.

**Technology flexibility**:

While it's often practical to stick to a single framework, the architecture allows for different technologies to be used in different parts of the application if needed.

**Independent deployment**:

Each microfrontend can have its own repository, build process, and CI/CD pipeline, allowing for faster and more frequent updates.

**Communication**:

Microfrontends communicate with each other and with the backend through well-defined APIs.

**Increased agility**:

Teams can deliver features and updates more quickly and frequently.

**Scalability**:

It is easier to scale the development of large and complex applications by dividing the work.

**Resilience**:

An issue in one microfrontend is less likely to bring down the entire application.

**Reduced coupling**:

It minimizes the code shared between different functional areas of the application.

**Increased complexity**:

Managing multiple repositories, build pipelines, and deployments can increase the overall complexity of the project.

**Higher costs**:

There can be increased costs associated with the overhead of managing more individual projects.

**Potential for excessive coupling**:

Without strong governance, it can lead to an unmanageable "splatter" of versions and dependencies
