Bitbucket

Bitbucket is Atlassian's cloud-based Git source code repository management platform, designed to help software development teams collaborate on code, manage branches, conduct code reviews, and automate their software delivery pipelines. Launched in 2008 and integrated into the Atlassian product ecosystem, Bitbucket is used by more than 10 million developers worldwide and is particularly popular in organizations that have standardized on Atlassian's Jira and Confluence products.

Bitbucket Repositories provide full-featured Git hosting with support for unlimited private repositories, branch permissions, and file-level access controls. Bitbucket's branching model supports all popular Git workflows including Gitflow, trunk-based development, and feature branch workflows, with configurable branch restrictions and mandatory reviewer policies that enforce code quality standards before merges are permitted.

Bitbucket Pull Requests (PRs) provide a structured code review workflow where developers can request feedback on proposed changes, reviewers can leave inline comments on specific lines of code, and approvals can be collected from required reviewers before merging. Bitbucket's review experience includes side-by-side and unified diff views, file navigation, comment threading, and AI-powered suggestions for improving code quality.

Bitbucket Pipelines is the platform's built-in CI/CD feature that enables teams to define automated build, test, and deployment workflows in a bitbucket-pipelines.yml file stored in the repository. Pipelines run on Atlassian-managed infrastructure in Docker containers, eliminating the need for separate CI/CD servers. Deployment environments with gating approvals and deployment tracking provide full visibility into what code is running in each environment.

Bitbucket's deep native integration with Jira Software enables automatic status updates on Jira issues based on branch names, commit messages, and pull request status, creating bidirectional traceability between project management and code changes. Bitbucket Data Center provides a self-managed, enterprise version for organizations with data residency requirements or large-scale development teams that need to host their source code on their own infrastructure.
