GitHub Discussions costs nothing for teams already on GitHub. This is not a feature tier limitation — Discussions is fully functional across all GitHub plans, including the free tier, with categories, Q&A format, pinning, and moderation tools available.
GitHub Discussions is included in all GitHub plans. Stack Overflow for Teams adds per-user monthly cost. GitHub wins decisively on pricing for teams already on GitHub.
This is the clearest route-level advantage for GitHub Discussions. If the team is already paying for GitHub — at Free, Team, or Enterprise tier — Discussions adds zero marginal cost. Stack Overflow for Teams requires a separate per-user subscription on top of existing tooling spend, adding both cost and vendor overhead.
Stack Overflow for Teams pricing is structured per-user per-month as a separate SaaS subscription. For small teams with low discussion volume, the absolute cost may be modest, but it adds a vendor relationship and billing line that GitHub Discussions eliminates entirely.
Route-specific evidence
