Where each one falls short

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

SignUpGenius

  • Specific pricing for paid plans is not published on the main site; users must visit the dedicated pricing page to see exact costs

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

SignUpGenius: Does SignUpGenius offer a free plan?

Yes. SignUpGenius is free to start with no credit card required. The free plan includes core signup functionality without monthly fees.

Source
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.

SignUpGenius: What do paid SignUpGenius plans include?

Paid plans add more customization options, higher communication limits, and the ability to remove ads from your signup pages. Standard payment processing fees apply to payments collected through the platform.

Source
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.
