What it does

NodeBB is forum software available free to run on your own server under GPLv3, with managed hosting sold separately. Plugins extend its discussions and administration, and the control panel lists those compatible with the installed version. Hosted subscriptions offer a 14-day trial that requires a credit card.

Start a NodeBB extension search inside the administrative control panel under Extend, then Plugins. That list contains extensions cleared for the installed NodeBB version. A plugin found elsewhere may still be incompatible, even if it is publicly available, and installing one can crash the forum. This matters when choosing an unusual login or posting feature for an established community.

Software and managed hosting

The application is free to download and install on your own server under GPLv3. You maintain that installation and its plugins. Managed hosting instead supplies traffic, storage and backup allowances:

Hosted plan	USD per month	Pageview allowance	Storage	Backups
Starter	20	50,000	5 GB	Weekly
Hamlet	100	500,000	20 GB	Daily
Village	250	2 million	100 GB	Daily
City	750	10 million	300 GB	Daily

All list unlimited staff users, so reading traffic and uploaded files are important capacity measures. Hosting begins with a 14-day trial and requires a card. Use Start Free Trial to create a hosting account with an email address and password; self-hosting uses an account within your own forum for administration. Larger organisations can request custom development, migration or integration services. Eligible public open-source projects can also apply for Starter-level hosting without charge, subject to NodeBB's approval.

Evidence

Current official documentation identifies a concrete compatible-plugin selection path and recovery boundary, while hosting details define traffic, storage and backup options. This establishes meaningful administration controls without a complete current discussion-to-moderation workflow.

Limits: Source-researched AI assessment. No hands-on product test or human fact-checking is claimed. An additional independent score check was waived by the owner.
