What changed in 2026
-
Circle repriced to Professional 199 / Scale 99/month.
-
Skool still has two plans: Hobby 99 with 2.9%. “Included” in the old table meant no extra platform fee; that is wrong, fees apply.
-
Zoho CommunitySpaces is sold in four tiers by user count: Lite (1,000 users, 100 GB, 20 spaces), Standard (2,000), Growth (5,000), Premium (10,000 users, 2 TB, unlimited spaces); zero transaction fees; 15-day trial. The vendor page shows tiers and limits (annual billing saves up to 20%) but no dollar amounts to the fetcher; monthly list prices of 99 / 399 from aggregators are unverified.
-
Substack: platform fee remains 10% of paid subscriptions plus Stripe processing (about 2.9% + $0.30, plus 0.7% Stripe Billing), per secondary sources; the Substack help page was blocked (HTTP 403).

Common Pitfalls & How to Avoid
Selecting Wrong Platform for Goal
- Risk: Investing in feature-heavy platform when simplicity needed
- Solution: Match complexity level to your needs (Skool simple, Circle mid, Zoho complex)
Underestimating Moderation Needs
- Risk: Community quality degradation without active moderation
- Solution: Use Circle’s AI agents (Scale plan, per the 2026 pricing page) or Zoho’s moderation workflows
Over-Reliance on Single Revenue Stream
- Risk: Platform algorithm changes (Substack) or member churn
- Solution: Diversify (membership + courses + events)
Ignoring Integration Needs Early
- Risk: Building on Skool then needing integrations
- Solution: Plan integration needs upfront; Zoho best for complex integrations
Not Planning for Scale
- Risk: Outgrowing platform limitations
- Solution: Choose based on projected scale (Zoho handles 10K+; others at 1-5K)
Migration Considerations
Moving between platforms is difficult. Key before committing:
- Data Ownership: Can you export member data? (Circle: limited, Zoho: better)
- Member Lock-in: Can members follow you? (Substack: portable, others: not)
- Content Portability: Can you take courses/content out? (Circle: difficult, Skool: easier)
Summary Decision Framework

| Content monetization | Substack | Circle |

Final Recommendation
Start with audience: Build on Substack (free, discoverable)
Then add monetization: Layer Circle or Skool for courses/membership
Enterprise scale: Move to Zoho when organizational needs emerge
Or choose single platform based on your primary motion:
- Writing monetization → Substack
- Membership business → Circle
- Cohort learning → Skool
- Enterprise community → Zoho
Open items
- Zoho CommunitySpaces dollar prices, API/MCP support, white-labelling, mobile apps and “full KB” are not confirmed by the vendor pages (the pricing page shows tiers and limits only).
- Substack: 10% fee plus Stripe (about 2.9% + $0.30, plus 0.7% recurring billing) agrees across 6+ secondary 2026 guides and the support article title is indexed, but support.substack.com returned HTTP 403 to the fetcher; Substack Live auto-clipping and Chat/Notes feature claims are unverified.
- Skool: “no public API” and Zapier-only rest on secondary sources (Zapier app page and integration guides).
- Qualitative statements (growth mechanics, “winner” verdicts, migration difficulty, scale thresholds) are editorial.
