Foundation Machines vs GitHub Copilot code review.
Copilot code review is a generalist native to GitHub. Sebastion AI is a security specialist. They're complements, not substitutes.
GitHub Copilot's code review is now the most-installed AI reviewer on GitHub — and it should be: it's native, bundled, and shipped to every Copilot Business seat. We don't try to out-distribute it. Sebastion AI is a security-only reviewer that runs alongside Copilot: every PR also gets a security pass that maps findings to CWE classes, flags exploitability, and posts ready-to-apply fixes. Think of Copilot as the generalist and Sebastion as the security specialist on the same PR.

Choose Copilot code review when
You already have Copilot Business and want a generalist reviewer on every PR with zero extra setup. It's native to GitHub and the integration is excellent.
Add Sebastion AI when
You want the same PR also reviewed by a security specialist. Sebastion posts findings tagged with severity and CWE id, flags exploitable bugs Copilot tends to soften, and files structured fix PRs. Free for public repos, $19/dev/mo for private — designed to sit next to Copilot, not replace it.
