- Works for small communities that can stay inside 2 staff seats and 10 categories
Look elsewhere if
- Tight if you grow: the free plan stops at 2 staff seats and 10 categories
- Pricey if you need SSO or events, which start at $500 a month
- Skip it if you want to sell courses, because it has no course checkout
- Watch out: plans are sold by staff seat, not by member count
Pick phpBB if
- Fits if you are comfortable running a PHP server
- Works for communities that want full control of their forum
Look elsewhere if
- Not for you if you do not want to manage a server, as the project sells no hosting

How we grade them
| 2.6GPADiscourseGood | 2.0GPAphpBBFair | |
|---|---|---|
| Value for money | BA free hosted plan exists, and Pro is $100 a month, above the $49 middle of courses and communities tools. SSO and events need Business at $500. | CThe software is free but you pay for hosting and run it yourself, which keeps it at the ordinary grade. |
| Free plan and trial | BThe free plan gives 2 staff seats, 10 categories, 5GB of storage and unlimited members, which a small forum can live on. | BFree outright under GPL-2.0, with no trial or plan caps, though you provide the server. |
| Features | CTopic forum, trust levels, chat, AI and translation, plugins and an API. The listing's gap: SSO, workflows, events and gamification need Business, and there is no course checkout. | CAdmin and moderator panels, styles, language packs, permissions and extensions cover forum basics. Extensions that touch the database can make upgrades harder. |
| Ease of use | CNo store rating on record. A hosted forum needs categories, settings and moderation set up before it feels like yours. | DNo store rating on record, and it must be installed and maintained on a PHP server. |
| Platforms and integrations | BWeb, iOS and Android apps, with plugins and an API. No desktop app. | CWeb only, and no integrations are listed. |
| Best for | a discussion forum, hosted or self-run | classic open-source forum software |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
