Choosing the right community platform is less about picking the objectively best software and more about finding the best fit for your specific needs, budget, and tech comfort level. This lecture walks through the most viable platforms for nonprofits—comparing costs, features, learning curve, and real-world strengths and limitations. There's no universal winner. The best platform is the one your team will actually use and your members will actually visit.
The Selection Framework
Before diving into platform specifics, answer these questions:
- Budget: Do you have $0, $100-500/month, or $500+/month to spend?
- Tech comfort: Is your team tech-savvy, tech-moderate, or tech-averse?
- Member base: Where are your members already? (Email, Facebook, LinkedIn, Slack, nowhere specific?)
- Primary use case: Is this mostly discussion? Announcements? Resource sharing? Event coordination?
- Growth horizon: Do you expect 50 members? 500? 5,000+?
- Moderation needs: Do you anticipate heavy moderation requirements or is your community generally self-policing?
- Mobility: Do members primarily access on mobile or desktop?
Your answers will heavily influence which platform is the right fit. Let's walk through the major options.
Facebook Groups
Cost: Free
Best for: Nonprofits with existing Facebook audiences; organizations wanting zero friction for members; communities that don't mind ads
Strengths:
- Zero cost, zero technical setup
- Most people already have Facebook accounts—no signup friction
- Strong mobile experience
- Built-in algorithms promote activity and engagement
- Easy to reach existing followers
- Decent moderation tools (templates, automation)
Limitations:
- Limited branding control—everything feels like "Facebook"
- No email integration or event coordination features beyond Facebook Events
- Conversations get buried over time; no good search or archive
- Algorithm changes can suppress community content with little notice
- Privacy concerns—Facebook owns member data
- Heavy ad presence (Facebook ads appear in group feeds)
- Limited features for resource libraries or structured learning
When to choose Facebook Groups: You have an existing Facebook audience (2,000+ followers), your members are already on Facebook, you want to minimize friction to joining, and you can accept that the platform is Facebook-branded with ads.
When to avoid: Your community needs sophisticated tools for events, learning, resource management, or you want full control over branding and member data.
Discord
Cost: Free (basic), $9.99/month (Nitro, for individual users—not needed for community management)
Best for: Tech-savvy communities; real-time discussion and chat; communities where members spend hours daily; gaming, tech, creative communities
Strengths:
- Zero cost for community management
- Excellent for real-time discussion and community culture
- Strong community around Discord (rich bot ecosystem)
- Powerful moderation tools and bots (automoderator, welcome bots, etc.)
- Very mobile-friendly
- Built for always-on communities
- Excellent video/audio chat capabilities
Limitations:
- Steep learning curve for non-tech users
- Designed for real-time chat, not asynchronous discussion
- Message history gets buried; not great for discoverability
- Not ideal for one-way announcements or formal updates
- Mobile app can feel overwhelming for casual users
- Limited email notifications (makes it hard to stay connected if you don't check daily)
- No built-in events, course, or learning management features
When to choose Discord: Your community is tech-forward (developers, designers, tech workers), members will be active daily, you want a conversational always-on space, and you can handle a learning curve.
When to avoid: Your members are older, less tech-comfortable, or expect a more formal space. Discord skews young and real-time; it's not ideal for asynchronous, professional communities.
Slack Communities
Cost: Free (basic, limited history), $12.50-$15/user/month (Pro and up)
Best for: Nonprofits where staff are already on Slack; tight-knit communities; organizations wanting seamless integration with internal operations
Strengths:
- Integration with your existing internal Slack workspace (if you use Slack for staff)
- Professional interface and culture
- Powerful search and knowledge management (good for archived conversations)
- Excellent for integrating apps and automations
- Strong mobile experience
- Email integration (you can reply to Slack messages via email)
Limitations:
- Expensive at scale (cost per member adds up with 200+ members)
- Free plan has limited message history (not sustainable long-term)
- Designed for work teams, not public communities (feels institutional)
- Not designed for one-way broadcasting or announcements
- Member onboarding is awkward (everyone needs an account; can't just use email invite)
- Powerful but complex for casual users
When to choose Slack Communities: Your staff are on Slack, you want tight integration with internal workflows, you have a small cohort (under 50 members) of highly engaged people, and cost isn't a constraint.
When to avoid: You need to scale to hundreds of members, you want a lower-friction member experience, or your community includes less tech-comfortable people.
Circle
Cost: $39-$99+/month (based on features and customization)
Best for: Nonprofits wanting a dedicated, polished, branded community platform; organizations with moderate budgets; communities focused on learning, discussion, and events
Strengths:
- Beautiful, modern interface with excellent customization
- Full branding control (your logo, colors, domain)
- Integrated events, courses, resources, and discussion tools
- Email integration (post via email, members get notifications)
- Strong moderation and member management tools
- Good analytics (member activity, engagement metrics)
- Works well on mobile and desktop
- Excellent customer support
- Member directory and profile features
Limitations:
- Monthly cost ($39-99) feels high for bootstrapped nonprofits
- Moderate learning curve (more complex than Facebook Groups, but easier than building custom)
- Requires members to create new accounts (signup friction)
- Limited free tier (can't trial at scale)
- API/integration options are moderate, not extensive
When to choose Circle: You have a $50-100/month budget, you want a branded professional platform, your community includes both tech-savvy and less technical members, and you value polish and support.
When to avoid: Your budget is under $50/month, you want a completely free option, or you need heavy customization or API access.
Mighty Networks
Cost: Free (basic), $149-399+/month (for features like custom branding, courses)
Best for: Nonprofits building large communities (500+); organizations wanting a full-featured, mobile-first platform; learning-focused communities
Strengths:
- Mobile-first design (excellent on phones)
- Full suite of features: discussion, events, courses, resources, member directory
- Free basic tier (good for small communities)
- Strong community features (member groups, mentoring)
- Good analytics and insights
- Professional support
- Works well at scale (500+ members)
Limitations:
- Free tier has significant limitations (no custom branding, limited features)
- Paid tiers are expensive ($149+/month) for feature-rich versions
- Interface can feel cluttered to less technical members
- Learning curve for full feature set
- Requires member signup (not as frictionless as Facebook)
- Email integration is less seamless than some competitors
When to choose Mighty Networks: You're scaling to 500+ members, you need a full-featured platform with courses and events, you have a budget of $150+/month for paid features, and you want mobile-first design.
When to avoid: Your budget is under $150/month, you want minimal features, or you need tight integration with external tools.
Discourse (Self-Hosted)
Cost: $50-400+/month (depending on hosting and customization), or free if self-hosted (but requires technical skill)
Best for: Tech-forward nonprofits; organizations wanting full control; communities that benefit from threaded discussion and search-friendly archives
Strengths:
- Fully owned and controlled (your data, your branding)
- Excellent for long-form discussion and knowledge building
- Powerful search and archive functionality
- Strong moderation tools built-in
- Works at any scale (small or large)
- Open source (can customize heavily if technical)
- No per-user cost (can scale to thousands without cost increases)
Limitations:
- Steeper learning curve for both admins and members
- Setup and maintenance require technical knowledge
- Less beginner-friendly than Circle or Mighty Networks
- Requires some budget for hosting
- Limited built-in tools for events, courses, or streaming
- Mobile experience is good but not as polished as mobile-first platforms
When to choose Discourse: You have a tech person on your team, you want to own your platform long-term, you're building a knowledge-base community, or you're planning to scale significantly and want to avoid per-user costs.
When to avoid: You lack technical staff, you need a plug-and-play solution, or you want built-in course or event management.
Building a Custom Platform
Cost: $5,000-50,000+ to build; $500-2,000/month for ongoing hosting and maintenance
Best for: Nonprofits with significant technical talent or budget; organizations with very specific needs that existing platforms don't meet
Strengths:
- Complete control over design, features, and experience
- Can integrate deeply with your existing systems
- No monthly platform fees (just hosting)
- Can build exactly what you need
Limitations:
- High upfront cost and ongoing maintenance burden
- Requires ongoing technical staff to maintain
- Takes months to build; you're not live in 30 days
- Responsibility for security, backups, updates falls on you
- Often less polished than built platforms
- Easy to over-engineer and create maintenance nightmares
When to choose custom: You have significant budget, unique requirements that no platform meets, and technical staff to maintain it long-term.
When to avoid: You're starting a community from scratch. Custom builds almost always take longer and cost more than expected. Pick an existing platform, and build custom only if you hit limitations of existing platforms.

Quick Decision Tree
Do you have an existing Facebook audience (2,000+)? → Facebook Groups
Do you want $0 cost and don't mind a learning curve? → Discord
Do you have $50-100/month and want something polished? → Circle
Do you have $150+/month and need full features (courses, events, learning)? → Mighty Networks
Do you want to own your platform long-term and have a tech person? → Discourse
Do you need something very custom and have significant budget? → Custom platform
Can You Switch Platforms Later?
Yes, but it's awkward. Community members develop habits; moving platforms requires effort from members to re-engage. Plan to stay on your chosen platform for at least 12 months. That said, if you choose wrong, it's better to migrate at month 3 than to stay in a bad fit for years. Here's what migration looks like:
- Export data: Most platforms allow some form of export (posts, members, etc.)
- Give notice: Tell members you're moving; provide the new link
- Redirect old content: If possible, create a redirect from old platform to new
- Migration loss: Expect 20-40% of members not to migrate with you; plan messaging to re-engage them
- Timeline: Plan 2-4 weeks for a migration with notification period
Migration is doable but not ideal. Choose thoughtfully, but don't paralyze yourself with perfect choice analysis. Pick the platform that best fits your current needs and budget, and plan to learn as you go.
The Nonprofit Default Recommendation
If you're a nonprofit starting your first online community with a limited budget, here's my recommendation: Start with Circle ($39-99/month).
Why Circle? It strikes the best balance of ease, affordability, features, and support. You get:
- A professional, branded platform (not generic Facebook or Discord)
- Integrated discussion, events, resources, and member management
- Works well for both tech and non-tech members
- Reasonable cost ($40-100/month)
- Excellent documentation and support
- Easy to migrate from if you outgrow it
If your budget is truly zero, choose Discord and invest in training your team. If you're already on Facebook and have an active audience there, start with Facebook Groups. If you're scaling to 500+ members or are tech-forward, consider Mighty Networks or Discourse.
But for most nonprofits launching their first community with $50-100/month budget, Circle hits the sweet spot.
