Trunk-Based Development

A branching model where developers integrate small changes into a single main branch (trunk) at least daily.

Definition

Short-lived branches or direct commits to trunk, plus feature flags for incomplete work, keep the trunk always releasable. DORA research associates it with high delivery performance.

Example

Developers merge small PRs to main several times a day, hiding unfinished features behind flags.

Exam tip

Trunk-based development + feature flags is the DevOps-preferred alternative to long-lived GitFlow branches.
