What it is
A micro-frontend architecture composes an interface from several independently built and deployed bundles rather than one monolithic application. Each bundle owns a domain, ships on its own release cadence, and is developed by the team responsible for it.
Why it matters
It is what stops a large frontend becoming a single release train where every change waits on every other. On Salesforce it also means a team can ship its own surface without redeploying the whole interface, while every bundle still shares one org’s data and permission model.
Key components
- Independently deployable bundles
- Domain ownership per bundle
- Independent release cadence
- Shared data and permission model
How it connects
On Salesforce each piece is a UI Bundle targeting the surface it belongs on — an internal app, an Experience site — so the composition is a deployment decision rather than a framework feature.
Good to know
Salesforce does not ship a "micro-frontend" product. It is an architectural pattern you compose from UI Bundles, and it is worth ruling out for a small app: the coordination cost is real and only pays off at scale.
