A pull request is a formal proposal to merge the changes on your branch into a shared branch, paired with a place for teammates to review them first. You make your edits in isolation, push the branch, and open a pull request that says "here is what I changed and why, please review and merge." Reviewers comment, automated tests run, and once it is approved the code becomes part of the main project. It is the standard way teams ship code together in 2026.
How a pull request works
The flow is consistent across platforms:
- Branch. You create a new branch off the main line so your work stays isolated.
- Commit and push. You make changes, commit them, and push the branch to the remote.
- Open the pull request. You target the branch you want to merge into and describe the change.
- Review. Teammates read the diff, leave comments, and approve or request changes.
- Checks run. Continuous integration runs tests, linting, and builds automatically.
- Merge. Once approved and green, the branch merges and is usually deleted.
The key insight: nothing touches the shared branch until the proposal is accepted.
Why teams use pull requests
| Benefit |
What it prevents |
| Code review |
Bugs and unclear code reaching production |
| Automated checks |
Broken builds and failing tests merging |
| Discussion in context |
Decisions getting lost in chat |
| A clear history |
Mystery changes with no explanation |
| Shared knowledge |
Only one person understanding a feature |
A pull request is as much a conversation as a mechanism. The diff plus the comments become a record of why the code looks the way it does, and the automated checks that gate it lean on continuous integration and delivery in 2026.
Pull request vs merge request
The concept is identical; the name differs by platform. GitHub and Bitbucket call it a pull request. GitLab calls it a merge request. Both mean: propose merging one branch into another with review. Do not let the naming confuse you.
How to open a good pull request
- Keep it small and focused. One logical change per pull request. A reviewer can actually reason about 100 lines, not 2,000.
- Write a clear title and description. Say what changed, why, and how to test it. Link the issue it resolves.
- Make it pass checks before asking. Run the tests and linter locally so reviewers are not chasing red builds.
- Self-review the diff first. Read your own change as if a stranger wrote it. You will catch leftover debug code and typos.
- Respond to comments, do not just resolve them. Explain or push a fix; silence stalls review.
Common mistakes
- The giant pull request. Mixing a refactor, a feature, and a formatting pass means nobody can review it well. Split it.
- No description. A diff with no context forces reviewers to reverse-engineer your intent.
- Ignoring CI. Merging past failing checks defeats the purpose of having them.
- Taking review personally. Comments are about the code, not you. The point is a better result.
What to skip
- Bundling unrelated changes to save a few clicks. It costs far more in review time and risk.
- Force-pushing over a branch under active review without warning; it scrambles the reviewer place in the diff.
- Merging your own pull request without review on a team project, unless your workflow explicitly allows it for trivial changes.
FAQ
What is the difference between a pull request and a commit?
A commit is a single saved change. A pull request bundles one or more commits on a branch and proposes merging them, with review attached.
Do I need a pull request for solo projects?
Not strictly, but the habit is worth keeping. It gives you a self-review step and a clean history, and it mirrors how teams work.
What does request changes mean?
A reviewer is blocking the merge until you address their feedback. Push the fixes, and they re-review and approve.
What runs the automated checks?
Continuous integration tools triggered by the pull request. They run your test suite, linters, and builds, then report pass or fail back to the pull request.
