FlatBB: multilingual out of the box, with a full forum feature set

Most “lightweight” forums cut corners. FlatBB is different: plain PHP 8.1+, no Composer/Docker/build step — but the feature list is what small communities actually need. Built-in languages Interface packs ship in the box: English, German, French, Spanish, Portuguese, Italian, Dutch Persian (فارسی) with full RTL layout mirroring Also: Header globe language switcher (remembered for visitors; members can set Preferences) Admin default language Per-visitor time zones for displayed times; site timezone for email/feeds/logs Post text follows its own writing direction (mixed-language communities work) Core features Discussion: nested categories (one level) + per-group permissions, tags, topics/replies, quotes, @mentions, Markdown + live preview, drag/paste image upload, likes, bookmarks, unread tracking, notifications. Discovery: full-text search (SQLite FTS5 / MySQL FULLTEXT), Latest / Top / Unread, clean URLs, RSS, sitemap, profiles & avatars. UX: Discourse/Flarum-style three-column layout that collapses on phones, dark mode, one-click upgrades. Admin: settings, categories, tags, users, groups, layout blocks, plugins, scheduled jobs, tools. Need more? The marketplace and AI-friendly plugin API cover SEO, social login (Google/GitHub/X), Q&A, levels, verified badges, Guard/2FA, drafts, and more.
