The answer, as recorded

# Best community forum software for small businesses **1. Discourse - the default pick for most small businesses.** Open source, free to self-host on a $10-20/mo VPS via Docker, or hosted from a genuinely free tier (2 staff seats, 500k pageviews, 5 GB) → $20/mo Starter → $100/mo Pro. Threads are indexed well by Google, so your community doubles as SEO-friendly support content, and pricing isn't per-seat, so growth doesn't punish you. Downside: self-hosting means you own upgrades and email deliverability. ([discourse.org](https://www.discourse.org/compare/circle), [costbench.com](https://costbench.com/software/community-platform/discourse/)) **2. Circle - if you're selling memberships, courses, or coaching.** ~$89/mo Professional with unlimited members, and it replaces a whole stack: discussion + courses + events + email + payments. Charges 2% transaction fees on top of Stripe (1% Business, 0.5% Plus). Choose this when the community *is* the product; it's weaker than Discourse for public, searchable support content. ([circle.so](https://circle.so/compare/vs-discord)) **3. Discord - if your audience is already there and it's chat, not archive.** Free tier, Nitro from ~$4.99/mo, near-zero adoption friction with younger/gaming/dev audiences. Real cost is structural: conversations aren't Google-indexed, so nothing compounds, and server subscription revenue carries a 10% platform fee (up to 30% on iOS). Good for hype and support, bad as a knowledge base. ([circle.so](https://circle.so/blog/discord-alternatives), [hashmeta.com](https://hashmeta.com/blog/discord-vs-slack-vs-circle-complete-community-platform-comparison-guide/)) **4. Invision Community - for a traditional forum you want managed.** Cloud plans from ~$89/mo, plus self-hosted licensing (annual renewal). Mature feature set - forums, gallery, blogs, commerce modules - and a good fit if you want an old-school message board without running servers. No free tier. ([capterra.com](https://www.capterra.com/p/184942/Invision-Community/), [invisioncommunity.co.uk](https://invisioncommunity.co.uk/best-community-platforms-in-2026-invision-discourse-circle-discord/)) **5. Flarum or phpBB - when the budget is truly $0.** Flarum is the modern, lightweight one (nice UI, smaller plugin ecosystem); phpBB is ancient-looking but has the deepest extension library and runs on any cheap shared host. Pick these if you have someone comfortable with a server and you'd rather spend time than money. ([hostinger.com](https://www.hostinger.com/tutorials/best-forum-software/), [websitesetup.org](https://websitesetup.org/best-forum-software/)) **6. Higher Logic Vanilla - customer-support communities with compliance needs.** WCAG-accessible forum plus built-in knowledge base, quote-based pricing. Realistically mid-market rather than small business, but it's the one to call if accessibility compliance is a hard requirement. ([bettermode.com](https://bettermode.com/blog/vanilla-forums-alternatives)) **Skip for now: Bettermode.** Frequently recommended in listicles, but Starter is $399/mo and Growth $1,500/mo - priced for funded SaaS, not small businesses. ([bettermode.com](https://bettermode.com/blog/all-in-one-community-platform)) **My actual advice:** start on Discourse's free hosted tier. It costs nothing to find out whether anyone shows up, and if the community works you can either pay $20-100/mo or export and self-host. Most small-business forums die of emptiness, not of missing features - so don't pay $89+/mo until you have proof of activity.
