GitHub
Microsoft-owned Git hosting and CI
Bitbucket
Atlassian Git hosting
GitHub is the default for open-source and most modern teams. Bitbucket makes sense when you're already deep in Atlassian (Jira + Confluence) — its Jira integration is the tightest anywhere. For most greenfield teams in 2026, GitHub wins; for existing Atlassian shops, Bitbucket stays sticky.
Pick GitHub when you want the biggest ecosystem, best CI, and Copilot.
Pick Bitbucket when you live in Jira and want deep issue-to-commit linking.

Use git remote to re-point, push --mirror, then import issues via atlassian-bitbucket-migration-assistant or the GitHub Importer. Bitbucket Pipelines YAML won't map 1:1 to GitHub Actions — rewrite the pipeline, redo deployment keys, and move Bitbucket Pipes to equivalent Actions. Expect 1-2 days for a mid-size repo.

Yes. Both have MCP servers installable via MCPizy (mcpizy install github and mcpizy install bitbucket). They work identically across Claude Code, Claude Desktop, Cursor, Windsurf, and any other MCP-compatible client. You can install both side by side and route queries in your agent's prompt.
GitHub has the biggest developer community, best third-party integrations, and polished Actions. GitLab is a single self-hostable DevOps platform with tighter security/compliance features and a more unified CI pipeline. GitHub wins on ecosystem; GitLab wins on self-hosting and built-in CD.
Vercel is optimized for Next.js (they maintain both) — best-in-class DX for React/Next apps with edge functions and ISR. Netlify is framework-agnostic, has a longer-running identity/forms product, and often wins for static Jamstack sites outside the Next.js world.
Vercel has the polished DX and Next.js feature parity. Cloudflare Pages is cheaper, globally faster at the edge, and pairs natively with Workers and R2 — but Next.js support has historically required extra config and lags on bleeding-edge features.
