Flarum vs NodeBB Comparison 2026
Flarum is self-hosted only, PHP-based, with no hosted tier sold by the project at all; you run it yourself or find a third party who will. NodeBB gives the same basic choice but adds an official hosted option: free to self-host under the GPL, or pay NodeBB itself from $20 a month, priced by pageviews rather than seats, with backups and SSL handled for you. Both are free, open source threaded forums. NodeBB is the one that will also run it for you if that work is unwelcome.
At a glance
- Both have a genuinely free tier.

Flarum
Forum software you host yourself
Flarum is forum software installed on your own server, so the discussion, the members and the domain belong to whoever runs it rather than to a platform. Extensions add what the core deliberately leaves out. There is no hosted tier and no monthly fee, which trades a bill for the work of running it. Anybody who does not want to think about PHP, a database and backups should buy hosted community software instead.
Our note
Price the hosting and an hour a month of your own time before calling this free, because that is what it actually costs and it is still far less than hosted community software. Choose it for ownership rather than for the saving, since the saving is real but the ownership is the part you cannot buy back later.
NodeBB
Forum software you can host yourself
NodeBB is forum software in the old sense, with categories and threads, built on Node.js and released under the GPL. You can run it on your own server for nothing, or pay NodeBB to host it and keep the plugins and backups somebody else's problem. Hosted plans are sized by pageviews rather than by seats, so a busy community with three moderators costs the same as a quiet one with thirty.
Why people weigh these two
- NodeBB instead of Flarum
- NodeBB runs on Node instead of PHP and offers its own hosted tier from $20 a month if self-hosting later feels like too much upkeep.
- Flarum instead of NodeBB
- Flarum costs nothing at any size, self-hosted like NodeBB but with no hosted plan to grow into, right for a community that will always run its own server.
Which one should you pick
Pick Flarum if PHP is the stack already comfortable to maintain, and a small, extension-driven core that adds features deliberately fits how the community should grow. It runs on inexpensive shared hosting rather than needing a dedicated server. There is no official hosted edition at all; self-hosting, or finding independent hosting for it, is the only route.
Pick NodeBB if the choice between self-hosting and paying somebody else to run it should stay open. Self-hosting is free and genuine under GPLv3, and the hosted plans start at $20 a month for 50,000 pageviews with unlimited staff accounts and backups included. It is built on Node.js rather than PHP, which matters for who on the team can actually maintain it.
Common questions
- Does Flarum offer an official hosted option like NodeBB does?
- No. Flarum has no hosted tier sold by the project at all; self-hosting is the only official route. NodeBB offers both: free self-hosting or a paid hosted plan from $20 a month if running a server is unwelcome.
- Are Flarum and NodeBB built on the same technology?
- No. Flarum is a PHP application, and NodeBB is built on Node.js, which affects who on a team is equipped to maintain either one long term.
- Is NodeBB's hosted plan cheaper than paying somebody to run Flarum?
- That depends entirely on what independent Flarum hosting costs, which is not stated here since Flarum sells no official hosted tier. NodeBB's own hosted price is clear and stated: $20 a month for 50,000 pageviews and 5GB of storage.
- Do both let a community grow without a per-member cost?
- Yes, on the self-hosted side of each: neither charges by member count when self-hosted, so a community of ten thousand costs the same as one of ten. NodeBB's hosted plans instead scale by pageviews, not members, if the paid route is chosen.
