Phabricator, once a robust open-source tool developed by Facebook for optimizing development workflows, is no longer maintained as of June 1, 2021, leading to the need for alternatives. It integrated code review, repository hosting, bug tracking, and project management, but its outdated interface and self-hosting requirements have prompted users to seek modern solutions. Among the alternatives are Graphite, which offers stacked pull request workflows, GitLab with its comprehensive DevOps features, and GitHub, renowned for its open-source project support and extensive community. Azure DevOps integrates seamlessly with Microsoft's ecosystem, Bitbucket aligns with Atlassian tools, Gitea offers lightweight self-hosting, and Gerrit provides collaborative code review. Each alternative caters to different team needs, whether for fast iteration, extensive DevOps capabilities, open-source collaboration, or integration with specific toolchains. Choosing the right platform depends on factors like team size, integration needs, ease of adoption, features, and budget, ultimately impacting productivity and software quality.
