Phabricator, an open-source tool developed by Facebook in 2010 for optimizing internal development workflows, is no longer actively maintained as of June 1, 2021, prompting users to seek alternatives. Known for its integration of code review, repository hosting, bug tracking, and project management, Phabricator facilitated centralized code review workflows and supported large codebases. Users now have various options, such as Graphite, GitLab, GitHub, Azure DevOps, Bitbucket, Gitea, and Gerrit, each catering to different team needs and infrastructure. Graphite, for example, offers fast iteration and collaborative development with features like stacked pull requests, while GitLab provides an integrated environment for the entire DevOps lifecycle. GitHub remains a leading choice for open-source projects, with extensive community support, and Azure DevOps integrates seamlessly with Microsoft's tech stack. Bitbucket excels in environments using the Atlassian toolchain, Gitea offers lightweight self-hosted solutions, and Gerrit focuses on enhancing code review processes. The choice of a Phabricator alternative depends on factors such as team size, integration needs, ease of adoption, feature requirements, and budget, as the right platform can significantly impact engineering productivity and software quality.
