TL;DR (60 seconds)
- → First structural decision: build or buy? 90% of successful communities in 2026 are on Discord, Circle, Skool or Slack — not custom-built.
- → If build: 4 critical pillars — ritualized onboarding, animation (weekly + monthly rituals), moderation (3-level protocol + ambassadors), monetization (subscription, cohorts, products).
- → Budget: €0 (self-managed Discord/Slack) to €80k (custom platform with integrated monetization). Circle/Skool: €89-300/month.
- → KPIs to include in the spec: active participation rate, 90-day retention, community → client/revenue conversion, community NPS.
A community is not a product to build, it is an ecosystem to orchestrate. The specification for a community platform must first settle the build vs buy question — in 9 out of 10 cases, buy wins. When build is justified (community with fine-grained monetization, differentiating UX, critical brand), the 4 pillars to define are: onboarding, animation, moderation, monetization.
Self-managed Discord/Slack €0, Circle/Skool/Mighty €89-300/month, custom platform €30-80k.
Discord setup 2-4 weeks, Circle/Skool configuration 4-6 weeks, custom 16-24 weeks.
For whom (precise persona)? For what (quantified business objective: leads, retention, LTV, recruitment)? Where (1-2 platforms maximum)? What (3-5 content pillars, rituals)? How do we measure? Without this framing, no tool will save the community.
Discord: massive communities (>5k members), free, bot flexibility. Slack: professional B2B, paid seats. Circle: cohorts, paywalled, coaching, €89-300/month. Skool: classes + community, €99/month. Mighty Networks: Circle equivalent. Custom: when monetization or UX are strategic differentiators.
Personalized welcome message (automated with human mention), introduction path (profile + 1 concrete action), welcome by an ambassador (not only by the CM), quick first win (exclusive resource, orientation call, quick feedback). Determines 80% of 90-day retention.
Recurring weekly ritual (same slot, same format): Monday goals, Wednesday Q&A, Friday wins. Monthly 'flagship event' ritual: masterclass, challenge, expert interview (60-90 min, maximum quality).
Public charter (1 page, tone, sanctions), 3-level protocol (benevolent public reminder → private message + formal warning → exclusion for toxic behavior), 3-8 ambassadors identified after 3-6 months absorb 40-60% of routine moderation, communicated CM time slots (not 24/7).
Free + upsell (training, coaching, templates), monthly subscription €49-299/month depending on perceived value, paid cohorts (€1,500-4,000 per participant, 20-50 participants, 2 cohorts/year), hybrid tiers (free access + premium). Stripe/Mollie for payment, provisioning webhooks.
Operational KPIs: 30-day active participation rate, posts/reactions ratio, active members per cohort, 7/30/90-day retention. Business KPIs: community → client conversion, revenue attributed to the community, community NPS. Tools: Orbit, Common Room, native exports + Google Sheets.
CRM (member sync → HubSpot, Flowayz), email (Resend, Mailchimp for offline sequences), calendars (Zoom, Google Meet for sessions), AI-assisted moderation (Spectra, WhalesAI), webhooks for payment provisioning.
Identification criteria (qualitative contributions > 3 months tenure), formalized role (badge, exclusive access, sometimes modest compensation), framed missions (moderation, onboarding new members, ritual animation), quarterly meetings.
Written manually, this specification often takes dozens of hours. Flowayz generates it in a few minutes from your brief.
Generate my specification →Discord for massive free communities (>5k members, tech, gaming, crypto). Circle for paid B2B communities with cohorts. Skool for communities + classes. Slack for professional B2B (<500 members, paid seats). Custom only when fine-grained monetization or differentiating UX are critical — which concerns fewer than 10% of projects.
Self-managed Discord: €0 in tools, 2-4 weeks of setup. Circle/Skool: €89-300/month + 4-6 weeks of configuration and content creation. Custom platform: €30-80k in development + 16-24 weeks + recurring hosting costs. The main cost is not the tool but the animation time.
Four rules. A one-page public charter with clear sanctions. A three-level protocol (reminder, formal warning, exclusion). Delegation to 3-8 ambassadors after 3-6 months. Defined CM time slots (for example: 9am-10am, 2pm-3pm, 6pm-7pm) shared with the community. Without these 4 rules, the CM burns out in 6 months.
Two operational and two business. Operational: active participation rate over 30 days (share of members who posted or reacted), 90-day retention. Business: community to client conversion (or attributed revenue), community NPS. Avoid vanity metrics (total member count, messages sent).
A forum (Discourse, vBulletin) focuses on structured asynchronous content (threads, tags, search). A modern community platform (Discord, Circle) adds synchronous features (live chat, voice, video), events (live streams, workshops), built-in monetisation (paywalls, subscriptions), gamification (badges, levels). Forums: better SEO. Communities: better engagement.
