Common Questions

For most teams, GitHub or GitLab native review is sufficient. Consider specialized tools for stacked PRs, advanced workflows, or self-hosted requirements.

Stacked PRs break large changes into smaller, independent reviews. Reviewers see less code at once, reviews happen faster, and parts can merge independently.

Yes, tools like Codacy catch style issues and potential bugs before human review, letting reviewers focus on logic and architecture.
