Monorepo vs polyrepo

Short summary

A comparison of monorepo and polyrepo strategies for managing code across teams. Monorepos offer atomic changes, unified tooling, and effortless code sharing, making them ideal for early-stage teams. Polyrepos provide hard boundaries and granular access control for larger teams with independent services. The recommendation: start with a monorepo and split only when ownership and release cycles genuinely diverge.

• •Monorepos are the right default for early-stage and single-product teams
• •Polyrepos suit teams with genuinely independent services and release cadences
• •Start monorepo, split later — merging repos back is far more painful than extracting one
