Branching strategy where small, frequent commits are integrated into a single shared main branch.
DESCRIPTION
Trunk-based development promotes continuous integration by committing directly to trunk (main) with short-lived branches. Teams rely on automation, comprehensive tests, and feature flags to maintain stability. It reduces merge complexity and accelerates delivery. Effective practices include commit discipline, code reviews, and fast feedback pipelines. It’s widely recommended for high-performing DevOps teams and modern CI/CD setups.
ALTERNATIVE DEFINITIONS
Trunk Based Development
Trunk-Based Development is a source-control branching model, where developers collaborate on code in a single branch called ‘trunk’ (or ‘main’).
Highlights collaboration on a single branch and naming of trunk/main.
Thoughtworks Technology Radar
Trunk-based development is a version control practice where developers commit changes to a single shared branch, called trunk or main.
Emphasizes CI-friendly practice recommended by industry leaders.
Atlassian

TOP QUESTIONS
What is Trunk-Based Development?
It’s a branching strategy where developers integrate small changes frequently into a single trunk (main) branch.
Category: Definition
Why is Trunk-Based Development popular?
It reduces merge conflicts, speeds delivery, and supports continuous integration with fast feedback.
Category: Relevancy
How do teams ensure stability with Trunk-Based Development?
Automated tests, CI pipelines, feature flags, and code reviews maintain stability despite frequent merges.
Category: BestPractices
What risks come with Trunk-Based Development?
Weak test coverage or undisciplined commits can break trunk; robust CI mitigates this risk.
Category: Risks
How does Trunk-Based Development compare to Gitflow?
Gitflow uses long-lived branches and releases; trunk-based favors short-lived branches and continuous delivery.
Category: Comparison
What team practices support Trunk-Based Development?
Commit frequently, keep changes small, enforce code reviews, and use feature toggles for incomplete work.
Category: HowTo
Is Trunk-Based Development suitable for large teams?
Yes, with strong CI/CD, clear coding standards, and disciplined branching policies.
Category: Opinion
What is a hot topic around Trunk-Based Development?
Progressive delivery and feature flagging integrated with trunk-based workflows are trending.
Category: Topic
How do you handle releases with Trunk-Based Development?
Use release trains, automated deployments, and flags to decouple deployment from release.
