Why Shift Runs as a Monorepo

Decision context

Shift has multiple surfaces with shared concerns: product pages, admin tooling, API contracts, and utility packages. A monorepo reduced drift and made cross-cutting updates predictable.

Benefits we observed

Shared types reduced integration bugs, code search improved architecture visibility, and coordinated releases became easier because app and package changes could move together.

Tradeoffs

Tooling complexity and dependency discipline are real costs. We address them with workspace boundaries, linting, and focused package ownership.
