We looked for open-source tools where members post, discuss, and learn like on Circle. We verified each project's license, recent activity, stars, and self-hosting in its repository. None bundles Circle's paid memberships and live events in one product. See our methodology for the full criteria.
Discourse is the most complete: trust levels, flagging, spam detection, themes, plugins, single sign-on, and data export. Flarum is a lighter, extensible forum with tags and real-time updates, and Storyden combines discussion, curation, and a wiki.
Apache Answer is a Q&A platform with reputation, Markdown, and webhooks. LearnHouse is a learning management system for building and selling courses with Stripe payments, which is a course platform rather than a forum.
LearnHouse is AGPL-3.0, but multi-tenancy, SCORM import, SSO, and audit logs are in its enterprise tier. Storyden is young, with about 340 stars.
Discourse is GPL-2.0. Apache Answer is Apache-2.0. Flarum is MIT. LearnHouse is AGPL-3.0 core with enterprise features. Storyden is MPL-2.0.
