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

Blackbaud Raiser's Edge

  • No published pricing on website - requires custom quote based on organization size and solutions
  • Pricing varies significantly by product and organizational complexity

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

Blackbaud Raiser's Edge: How much does Raiser's Edge NXT cost?

Blackbaud does not publish pricing for Raiser's Edge NXT or other products on their website. Pricing is customized based on your organization's size, goals, and the solutions you need. You must submit a form to request a personalized quote.

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.

Blackbaud Raiser's Edge: How is Blackbaud pricing calculated?

Blackbaud pricing is based on several factors including organization size, number of users, selected solutions or modules, and the level of support and services desired. Pricing is designed to scale with organizational needs.

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.

Blackbaud Raiser's Edge: Does Blackbaud charge hidden fees?

No, Blackbaud pricing is structured to be transparent with no hidden fees. Their representative walks through all costs during consultation before you move forward.

Source
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.
