How to build an online community platform: practical steps and platform prices

Build on a hosted platform unless you truly need custom software

To build an online community platform, most organizers should rent one, not code one: choose a hosted community product, set up a few spaces, test with a small group, then invite everyone else. Hosted platforms already include member accounts, posts, events, payments and mobile apps. Building your own only makes sense when you have developers and a need no product meets, and even then an API on top of a hosted platform is usually the shorter path.

Before you start you need three things: a clear statement of who the community is for, a way to reach those people (an email list, an existing group or a meeting you already run), and one person who will host it every week. No platform supplies those.

Seven steps from idea to a working community

1. Write down the job. Who is it for, what will they do together, and what must the platform do. A one-page requirements brief is enough.
2. List what you already have. Members, files, recurring events and moderators. This matters most if you are moving an existing group.
3. Pick a platform from the table below and start a trial. Mighty Networks and Circle both offer a 14-day trial without a credit card.
4. Set up the minimum. One place for discussion, one for events and a welcome post. Add courses or paid plans later.
5. Run a pilot. Invite a small group first and watch where they get stuck. See the pilot plan.
6. Invite in waves. On Mighty Networks you can share an invite link or, on Launch and above, upload a CSV of email addresses, which is sent in batches of 50.
7. Hand out roles and review. Name moderators, agree rules, and check after a month who joined and who posted.

Platform entry prices, checked on 3 October 2026

Circle's month-to-month price was not shown in the page text we read. A fuller field is on our best community platforms page.

Worked example: 30 paying members at $48 a month

Mighty's pricing page uses 30 members at $48 per month as its sample membership, which is $1,440 a month in sales. Here is what the platform itself would take at the listed rates, before payment processing, which this comparison does not cover.

The lesson is that a low subscription with a high percentage fee stops being cheap once people pay you. For a free community the order reverses, and Skool Hobby at $9 is the lowest price in the table.

Where Mighty Networks fits, and where it does not

Mighty Networks fits organizers who want discussion, events, courses and paid membership in one product with iOS and Android apps, and who expect to charge members. Launch has no cap on members or Spaces.

• If cost is the main limit and you will not charge, Skool Hobby or Mighty's Explore plan costs less.
• If you need Zapier, Kit or API access, those start on Mighty's Scale Plan at $179 per month with annual billing, so budget for that tier. Circle lists its APIs on the Business plan at $199 per month on annual billing.
• If you want apps under your own name in the app stores, that is Mighty Pro at custom pricing.
• If your current group works and members are active there, staying put is a valid choice. See when not to move.

The most common mistake: building everything before anyone arrives

New hosts often create many spaces, a full course and several paid tiers, then invite everyone at once to an empty room. A community with three busy areas feels alive. One with fifteen quiet areas does not. Start with the minimum from step four, invite the pilot group, and add a space only when members ask for it. Prices were read on 3 October 2026 and can change.
