Vanilla Forums began as an open-source project, but its maintainer, Higher Logic, ended support for the open-source edition in 2025 and now sells Vanilla only as hosted cloud software, with plans starting around $599/month. That makes it a genuinely closed, subscription-only product going forward, even though old open-source code is still archived on GitHub.
Since Vanilla's hosted plans gate features like reactions, badges, and polls behind premium tiers, self-hosting an actively maintained open-source forum is the more direct way to get comparable functionality without a recurring SaaS bill.
