"Forum sites" means two different things depending on what you actually want. Some people want to join a discussion that already exists, somewhere with real threads and real answers on a topic they care about. Others want to start one, and are trying to figure out which forum software fits a small community and a small budget. This guide covers both. Part one is places worth joining. Part two is software worth building on.
Forum sites worth joining
These are general-purpose and topic-specific forums that are well established and still active. None of them need an introduction if you already spend time online, but the list is a useful starting point if you are looking for a place to ask a real question and get a real answer.
| Site | Format | Best for |
|---|---|---|
| Link and text aggregator, organized into subreddits | Broad topic coverage, fast answers, voting-based ranking | |
| Hacker News | Link and discussion board | Tech, startups, and programming news with thoughtful comments |
| Stack Overflow / Stack Exchange | Question and answer network | Programming and other technical questions with a single best answer |
| Quora | Question and answer site | General knowledge questions answered by other users |
| Discourse-hosted communities | Modern threaded forum software, run by individual companies and projects | Official support and discussion for a specific product or open source project |
| Lemmy | Federated (Fediverse) link aggregator | People who want a Reddit-style forum without one company owning it |
| ResetEra | Traditional threaded forum | Gaming and games-industry discussion |
| Something Awful | Traditional threaded forum | General internet culture and long-running off-topic discussion |
| XDA Forums | Traditional threaded forum | Android modding, rooting, and custom ROM development |
| MacRumors Forums | Traditional threaded forum | Apple product news, rumors, and buying advice |
| Bodybuilding.com Misc | Traditional threaded forum | General off-topic discussion attached to a fitness site |
| Head-Fi | Traditional threaded forum | Headphones and personal audio gear |
Reddit is organized into subreddits, one per topic or interest, with posts ranked by upvotes and downvotes. It is the default place most people search when they want an opinion on almost anything, and its breadth is the main advantage over a single-topic forum.
Hacker News
Hacker News is a link-and-discussion site with a comment culture that stays more substantive than most of the internet, especially for programming, startups, and technology news. It has almost no visual design and no algorithmic feed, which is part of the appeal for people tired of both.
Stack Overflow and Stack Exchange
Stack Overflow is built around one question, one accepted answer, which makes it the fastest way to solve a specific programming error. Stack Exchange is the same question-and-answer format applied to dozens of other topics, from cooking to law to worldbuilding.
Quora
Quora lets anyone ask a question and lets anyone, including people who claim relevant expertise, answer it. It works well for general knowledge and opinion questions where there is no single correct answer to accept.
Discourse-hosted communities
Many software companies and open source projects run their own public support and discussion forum on Discourse, including Discourse's own community forum. If a product you use has an official forum, there is a good chance it runs on Discourse, and it is usually the best place to ask a question the documentation does not answer.
Lemmy
Lemmy is an open source, federated alternative to Reddit. Instead of one company running every server, anyone can run a Lemmy instance, and instances can talk to each other. It is a good fit if you like Reddit's format but want a community that is not owned by a single company.
ResetEra
ResetEra is a traditional threaded forum focused on gaming and the games industry, with the kind of long, detailed threads that gaming subreddits rarely sustain.
Something Awful
Something Awful is one of the longest-running general forums on the internet and has shaped a lot of internet humor and slang that later spread far beyond it. It requires a small one-time registration fee to post, which keeps the signal-to-noise ratio unusually high for a forum this old.
XDA Forums
XDA is the reference forum for Android modding, rooting, and custom firmware. If a phone can be modified, there is almost certainly a thread about it on XDA.
MacRumors Forums
MacRumors runs a large forum alongside its news coverage, and it is a reliable place to read informed speculation and hands-on opinions about upcoming Apple hardware and software.
Bodybuilding.com Misc
The "Misc" board on Bodybuilding.com is technically off-topic but has been a well-known corner of internet culture for a long time, mixing fitness talk with general discussion.
Head-Fi
Head-Fi is the dedicated forum for headphones and personal audio, with detailed gear reviews and buying advice from people who take the hobby seriously.
Beyond this list, most hobbies and car models still have a long-running independent forum. A search for the topic plus "forum" often surfaces it faster than a general social platform will.
Platforms to build your own forum
If none of the above fits your topic, or you want a forum your own community owns, here is the current landscape of forum software, hosted and self-hosted.
| Platform | Hosted or self-hosted | Cost model | Best for |
|---|---|---|---|
| Forumera | Hosted | Free plan, Pro at $19/month | Getting a searchable forum live in minutes without server management |
| Discourse | Self-hosted or managed hosting | Open source; managed hosting from $100/month | Teams that want deep customization and are comfortable with Docker, or will pay for managed hosting |
| phpBB | Self-hosted | Free, open source | Budget self-hosted forums on standard PHP hosting |
| MyBB | Self-hosted | Free, open source | Lightweight, straightforward self-hosted forums |
| XenForo | Self-hosted | Commercial license | Polished, add-on-friendly forums for admins willing to pay for software and host it themselves |
| Flarum | Self-hosted | Free core, paid extensions | A modern, single-page-app forum look on a lighter codebase |
| NodeBB | Self-hosted or hosted plans | Open source core, paid hosted plans available | A more modern, real-time forum feel |
| ProBoards | Hosted | Free with ads, paid tiers to remove them | Free legacy-style hosted forums with a large template library |
| Tapatalk Groups | Hosted | Free with paid upgrades | Mobile-first forum communities |
| bbPress | Self-hosted (WordPress plugin) | Free, open source | Adding a simple forum to an existing WordPress site |
| Discord | Hosted, not a forum | Free, paid Nitro add-on | Real-time voice and text, not searchable or indexed by Google |
| Skool | Hosted, not a forum | Paid subscription, trial only | A bundled community feed, courses, and payments in one paid product |
Discord and Skool are included because people searching for "forum sites" often mean "a place for my community to talk." Neither is a forum: Discord is real-time chat, not indexed by search engines, and Skool bundles a feed with courses and payments behind a paid subscription with no free plan. See forum vs. Discord for the fuller breakdown.
How to pick
Hosted vs. self-hosted. Hosted platforms like Forumera, ProBoards, and Tapatalk Groups handle servers, backups, and updates for you. Self-hosted software like phpBB, MyBB, XenForo, Flarum, NodeBB, and bbPress gives you control of the code and data, but you own the server and the patching. Discourse can go either way.
Cost. Free self-hosted software like phpBB and MyBB still costs money to run once you add hosting, a domain, and your own time. A commercial license like XenForo's is a real upfront and renewal cost on top of hosting. Hosted platforms fold that into one bill, or in Forumera's case, offer a genuinely free tier with no time limit before you ever pay anything.
Control. Self-hosting wins if you need custom code, specific plugins, or data on infrastructure you control. Hosted platforms trade some of that control for not having to think about servers at all.
Mobile. Most current forum software, hosted and self-hosted, is responsive out of the box. Tapatalk Groups is built specifically for a mobile app experience if that is the priority. Forumera's UI is mobile-first by default.
SEO. A forum's biggest long-term advantage over chat tools is that its threads can be indexed and found on Google years later. That only works if pages are server-rendered and crawlable, which is not guaranteed on every platform or every plugin configuration. Check this specifically if organic search traffic is part of why you are building a forum instead of using a chat app. See the forum vs. Discord and forum vs. Slack comparisons for how that plays out against non-forum tools.

Starting your own forum in an afternoon
If you want a working forum today rather than a server-provisioning project, here is what that looks like on Forumera.
- Pick a subdomain. Sign up and choose a name; your forum is live at yourname.forumera.com in about two minutes.
- Set up categories and boards. Group your topics into a small number of boards to start.
- Set roles and access. Assign moderators and decide which boards are public or invite-only.
- Invite your first members. Post an announcement thread and seed a few discussions yourself.
- Grow from there. Add tags, polls, and reactions as activity picks up, and connect Discord or RSS if your community already lives partly elsewhere.
The free plan covers unlimited members, threads, and posts, with moderation tools, 6 UI languages, and 10 themes; free forums auto-archive after 90 days of inactivity if nobody posts. Pro is $19/month and adds a custom domain, removes the "Powered by Forumera" footer, stops auto-archiving, and adds 100 AI credits a month plus priority email support. There is no self-hosted version and no plugin marketplace, so if you need custom code, look at Discourse or XenForo instead.

Frequently asked
What is the best forum site to join for general discussion?
Reddit has the broadest topic coverage. Hacker News is better if you want a smaller, more technical crowd. For a single-topic community, a dedicated forum like XDA, MacRumors Forums, or Head-Fi is usually a better fit than a general platform.
What is the best forum software for a small community?
For a new, small community, a hosted platform like Forumera removes the server-management step entirely and has a genuinely free plan. If you need custom plugins or already run other services, a self-hosted option like phpBB, MyBB, or Discourse is worth the extra setup work.
Is Reddit a forum?
Functionally yes. Reddit is organized around threaded discussion inside topic-based subreddits, which is the same basic structure as a traditional forum, just run by one company at massive scale with a voting-based ranking system layered on top.
Should I use Discord or a forum for my community?
Use Discord for real-time chat and use a forum for anything that should still be useful and findable in a year, including guides, FAQs, and recurring questions. Many communities run both side by side rather than choosing one. See Discord alternatives for more on that tradeoff.
Whether you are joining an existing forum or building your own, the right platform depends on what you actually need: reach, control, or speed to get something live. If it is the third one, create your forum and have it running before the afternoon is over.
