Monorepo vs polyrepo in 2026: how to choose without dogma

Both monorepos and polyrepos work at scale. The question is which set of trade-offs fits your team, your tooling, and your release cadence.
When monorepos shine
Shared types, atomic refactors, and one CI to rule them all. With modern tools like Turborepo or Nx, the tooling cost is finally reasonable.
When polyrepos win
Independent release cycles, clear ownership, and minimal blast radius. Large orgs with strong service boundaries often prefer them.
Hybrid is fine
Most mature companies end up with a frontend monorepo and a handful of service repos. Purity is overrated.
