Community Forum
The Top Community Forum Software for Businesses (2026)
Online forums did not disappear, they grew up. The message-board software that ran customer communities a decade ago still exists, and some of it is still free, but the market added a whole class of hosted community platforms that bundle discussion with courses, events, memberships, and real-time chat. So the question is no longer just which forum script to install. It is whether you want a classic forum you run yourself or a modern community platform someone else hosts.
For a business, a community does the same job it always did: it gives customers a place to ask questions, help each other, share feedback, and stay engaged with your brand. A good one cuts support tickets and builds loyalty. This guide covers the best community and forum software in 2026, split into open-source options you host and paid platforms that host for you, with current pricing.
Key takeaways
- Discourse is the modern open-source standard. Self-host it for free, or use managed hosting from $100/month. Best all-around pick for support and discussion communities.
- Circle is the leading hosted platform for branded and creator communities, from $89/month, pairing discussion with courses and events.
- Invision Community (the product formerly called IP.Board) is the all-in-one branded suite, from $89/month cloud, with forums, blogs, and commerce.
- phpBB, SMF, and MyBB are still free and still maintained if you want a classic self-hosted forum on a budget.
- vBulletin lives on with cloud plans from $19.95/month, and Bettermode (formerly Tribe) serves larger brands from $399/month.

Open-source forums you host yourself
Discourse: the modern open-source standard
Who it is for: Businesses that want a clean, modern discussion or support community and are comfortable running software or paying for managed hosting. Discourse has become the default choice for open communities, from software projects to product support.
What you get: Real-time updates, trust levels that hand moderation to your best members, strong spam controls, single sign-on, a large plugin ecosystem, and a genuinely good mobile experience. It reads like a modern app, not a 2010 message board.
What it costs in 2026: The software is free and open source if you self-host. Managed hosting from Discourse runs $100/month for the Pro plan and $500/month for Business, with enterprise pricing on request.
Where it falls short: Self-hosting means you own updates, backups, and security, which is real work. The hosted plans jump from $100 to $500 with little in between, so mid-size communities can feel caught in the gap.
phpBB, SMF, and MyBB: the free classics, still here
Who it is for: Teams that want a traditional message board, own the server, and would rather spend zero on software. All three from the old version of this list are still free, still open source, and still maintained.
What you get: phpBB remains the best known, with a huge library of styles and extensions and a light footprint. SMF ships a fuller feature set out of the box, and MyBB offers an easy admin experience with strong plugin support. Any of them will run a capable forum for free.
Where they fall short: The interfaces look dated next to Discourse or Circle, mobile is weaker, and you are responsible for hosting, updates, and spam management. For a low-traffic community on a tight budget, that trade can still be worth it.
Hosted community platforms someone else runs
Circle: branded communities with courses and events
Who it is for: Brands, creators, and membership businesses that want a polished community tied to content. Circle became popular precisely because it combines discussion with courses, events, and paid memberships in one hosted product.
What you get: Spaces for discussion, live streams and events, course hosting, member payments, and a modern mobile app, all under your own branding with nothing to install.
What it costs in 2026: Professional is $89/month and Business is $199/month, with a custom Circle Plus tier above that. A 14-day free trial is available.
Where it falls short: It is built more for creator and membership communities than for high-volume technical support, transaction fees can apply on paid memberships depending on tier, and you do not control the underlying platform the way self-hosting allows.
Invision Community: the all-in-one branded suite
Who it is for: Businesses that want a full community suite under their own brand, with forums at the center plus blogs, galleries, and commerce. This is the product that used to be called IP.Board, now sold as Invision Community.
What you get: Forums, blogs, downloads, a store and subscriptions, strong moderation, and a marketplace of add-ons. You can run it in Invision’s cloud or license it to self-host, which is a flexibility most modern platforms do not offer.
What it costs in 2026: Cloud plans start at $89/month for Creator (billed annually) and climb through Team at $229/month to Business at $549/month, with enterprise pricing above that. A self-hosted license is also available.
Where it falls short: The feature depth brings complexity, setup takes more effort than a plug-and-play platform, and the higher tiers get expensive as your community grows.
vBulletin and Bettermode: the budget classic and the enterprise option
vBulletin is still around for teams that want a traditional, powerful forum with a hosted option. vBulletin Cloud starts at $19.95/month (Bronze) and runs to $74.95/month (Gold), with a self-hosted license also sold. It is a reasonable budget choice if you specifically want a classic forum rather than a modern community app.
Bettermode (formerly Tribe) sits at the other end. It is an API-first, heavily customizable platform aimed at larger brands that want a community built into their product. Pricing starts at $399/month for Starter and $1,500/month for Growth, with enterprise quotes above that, so it is a fit when a community is core to the business rather than a side feature. Discord is worth naming here too: it is free and dominates real-time community chat, though it is a chat platform rather than a searchable, threaded forum.
What happened to the old top-forum list
If you came from the older version of this page, the news is mostly good. phpBB, SMF, and MyBB are all still free, open source, and actively maintained, so the budget options held up. vBulletin is still sold and now leads with a cloud subscription rather than a one-time license. The one rename to know: IP.Board is now Invision Community, the same lineage with a broader suite and a cloud option. The biggest change is not a vanished product but a new category, the hosted community platform, led by Discourse on the open-source side and Circle on the branded side.
How to choose the right one
You want a modern community and can self-host, or pay for hosting: Discourse. It is the strongest all-around pick and free if you run it yourself.
You are building a branded or paid membership community: Circle. Discussion plus courses, events, and payments in one hosted product.
You want a full suite under your own brand and the option to self-host: Invision Community.
You want a classic forum for as little as possible: phpBB, SMF, or MyBB if you can host it, or vBulletin Cloud from $19.95/month if you want someone else to.
Frequently asked questions
What is the best free community forum software?
Discourse if you want a modern experience and can handle self-hosting, or phpBB, SMF, and MyBB for a classic message board. All four are free and open source. Your only costs are server hosting and the time to maintain them.
Is IP.Board still available?
Yes, under a new name. IP.Board is now sold as Invision Community, the same product line expanded into a full suite with forums, blogs, and commerce. It runs in Invision’s cloud from $89/month or as a self-hosted license.
Should I use a forum or a chat platform like Discord?
They solve different problems. A forum like Discourse creates searchable, threaded discussions that keep answering questions for years, which is ideal for support. Discord and similar chat tools are better for real-time conversation but harder to search later. Many businesses run both.
How much should a business budget for community software?
You can start at $0 with a self-hosted open-source forum, plus a few dollars a month for hosting. A hosted platform runs roughly $20 to $200/month for most small and midsize communities, and enterprise-grade platforms move into the hundreds or thousands per month. Match the tier to how central the community is to your business.
Self-hosted or hosted: which should I pick?
Choose self-hosted (Discourse, phpBB) if you have technical help and want full control and the lowest software cost. Choose a hosted platform (Circle, Invision Community cloud) if you would rather pay a monthly fee and never think about servers, updates, or security patches.
The verdict
For most businesses in 2026, Discourse is the best starting point: it is modern, well supported, and free to self-host, with managed hosting from $100/month when you would rather not run it. If your community is about brand and membership rather than technical support, Circle is the cleaner fit, and Invision Community wins when you want a full branded suite with the option to self-host.
The budget classics, phpBB, SMF, and MyBB, are still free and still fine for a straightforward forum. Most of these offer free trials or free software, so stand up a test community, invite a few real users, and see which one your members actually enjoy posting in before you commit.
