Micro-Frontends

Micro-frontends and a modular monolith can share strong code boundaries. Their practical difference appears when old and new parts coexist: shell contracts, assets, dependency versions, cross-app state, and rollback need an operating agreement.

Every micro-frontends pitch I've seen leads with the technical benefits — independent deploys, framework isolation, smaller bundles per team. Almost none of it holds up unless the real problem was organizational to begin with. Conway's Law isn't a fun fact here. It's the actual justification.
