[!todo] Seed note. A starting point, not a finished note yet.
A “forge” is a web platform that hosts version-controlled repositories and adds the collaboration layer around them: pull/merge requests, issue tracking, code review, CI/CD, and access control. The term predates GitHub (SourceForge coined the shape) but now describes the GitHub / GitLab / Bitbucket category plus self-hosted options like Gitea and Forgejo. The forge matters because it, not Git itself, defines the review workflow a team lives inside. Standardizing on the pull-request forge model is what makes code review a shared, cross-industry bottleneck. Seeded from Code Review Tooling Market - GitHub, GitLab, and the PR Review Bottleneck.
