  • They diverge on capability: GuideStar covers Nonprofit profile, Tendenci covers Open-source licence.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GuideStar

  • GuideStar and Foundation Directory are being retired and merged into a single Candid platform, per Candid's own learning.candid.org help pages, with existing subscribers redirected to log in at app.candid.org
  • Candid's own pricing page lists Candid Premium (annual) at $1,199 per year in USD, and $219 per month if billed monthly, with an Ultimate annual tier at $1,699 per year adding compliance monitoring features
  • Candid's free tier limits search results, profile views and dashboards; full grants and profile data downloads are capped even on Premium annual, at 1,000 grants downloads and 5,000 profile downloads per month

Tendenci

  • Self-hosting is a real operational commitment, and organisations without technical capacity should not treat the free licence as a free system
  • The community is small compared with mainstream open-source projects, so answers are harder to find and contributors are few
  • The interface is dated against the commercial association platforms and this is the most common user complaint
  • Fewer integrations than commercial competitors, and building them is a development task rather than a configuration one
  • Feature depth in events and continuing education is behind the specialist commercial systems

Answered from the vendors’ own pages

Tendenci: Is Tendenci really free?

The software is, under an open-source licence with no per-member fee. Running it is not: hosting, updates, backups and security are the organisation responsibility unless managed hosting is purchased.

Tendenci: Who should choose it?

Organisations with a genuine requirement to control their own data, and the technical capacity to act on it. Choosing it purely to avoid subscription cost usually ends badly.

Tendenci: Can I move my data out?

Yes, entirely. That is the point. Data lives in a PostgreSQL database you control, and there is no vendor holding it.

Tendenci: How does it compare to Wild Apricot?

Wild Apricot is easier, better supported and better looking. Tendenci is the answer when data ownership is a requirement rather than a preference.

Tendenci: Is it actively maintained?

It is developed openly on GitHub with a small team and community. Check recent commit activity before committing, as with any small open-source project.
