Why Are Repositories Like GitHub and Bitbucket Needed?

Repositories track every change to your codebase over time. Without them, you’re one laptop failure or one bad overwrite away from losing work — and you have no clean way for multiple people to collaborate.

Git-based hosts like GitHub and Bitbucket add review, branching, history, and a single source of truth. For a founder, that means you own the code independently of any one developer, can audit what changed, and can onboard the next engineer without archaeology.
