Trunk-based development (TBD) is a workflow where developers work off a single, shared main branch, integrating their changes frequently, which contrasts with the feature branch workflow that involves isolated, long-lived branches leading to siloed work and potential merge conflicts. TBD is increasingly favored by organizations aiming for high-velocity software development due to its benefits such as enhanced team synchronization, fewer merge conflicts, and streamlined continuous integration and delivery processes. This approach promotes regular commits, ensures the codebase remains current, and facilitates faster feedback loops, which are critical for maintaining a deployable state. Industry giants like Google and Facebook have long employed TBD, and data indicates that it leads to higher development speed, with a significant reduction in pull request open-to-merge time compared to other methods. As of 2023, the trend toward TBD continues to grow, with nearly 80% of pull requests being based on main branches, and it is advocated as a best practice for organizations looking to improve software development efficiency and quality.
