Nexus review
A self-hosted forum with rich discussions, moderation, extensions, and PWA push notifications.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Nexus is open-source, self-hosted forum software for individuals and small organizations running an online community on their own server. Its spaces and sub-spaces organize discussion threads, while Markdown, embeds, mentions, emoji, nested replies, voting, reactions, pinned threads, and accepted answers support different conversation styles. Full-text search spans posts and replies. Profiles, groups, direct messages, notifications, activity feeds, badges, points, and leaderboards add community features beyond basic message boards.
Administration covers registration, branding, email, storage, and progressive web app settings. Moderators can use bans, mutes, suspensions, reports, and approval mode; member groups and role-based permissions help define access. Extensions and themes install from a URL or built-in store. Nexus supports Google and GitHub OAuth, Postmark, Resend, Mailgun, SMTP, Cloudflare R2, and S3-compatible storage. Deployment uses Docker Compose, and the software is distributed under the MIT license. The published setup model is self-hosted, so the operator is responsible for running the forum on a server.
The PWA can be installed on iOS and Android and supports push notifications, but Nexus does not offer native App Store or Google Play apps. That makes it a fit for communities comfortable with browser-based access and their own hosting, rather than teams that require native apps or a managed hosted service. With docs and community support, plus extensive moderation and permissions, it suits small self-hosters who want control over community setup. Organizations requiring SSO should look elsewhere; Nexus does not support it.
