Which branch typically contains the production-ready version of code?

The main branch is typically where the production-ready version of code is stored. This branch represents the stable and official version of the code that is deployed in a live environment. It is common practice in version control systems, including those used in continuous integration/continuous deployment (CI/CD) workflows, to maintain a clean and reliable state in the main branch. Developers will merge their approved feature branches into the main branch once the code has been tested and reviewed, ensuring that only well-vetted and functional code reaches production.

In contrast, feature branches are created specifically for developing new features or changes in isolation. They contain ongoing work that has not yet been merged into the main branch, meaning the code there may not be stable or production-ready. The development branch is often used for integration purposes, where new features from various branches come together, but it may not always be stable enough for production. Similarly, the sandbox branch typically serves as an experimental environment rather than one designated for production-readiness. Thus, the main branch serves as the cornerstone for production, ensuring stability and reliability in the live application.
