Tendenci

Tendenci fits an association that wants ownership of its membership website and event workflow, with technical help available to operate it. The free licence can be attractive, but the meaningful budget is the deployed service: hosting, upgrades, payment configuration and staff support.

Free open-source licence; hosting and implementation cost extra

Honest Limitations

Operating the website is part of the project

A self-hosted deployment needs server administration, upgrades, backups and payment configuration. The licence price does not cover those tasks.

Cancellation charges depend on the gateway

The event documentation says its configured cancellation-fee feature works only with Stripe payments.

Commercial hosting needs fresh confirmation

Current managed-hosting prices and service commitments were not established. Older directory package prices should not be treated as a current offer.

Hidden Costs to Watch

  • ! Server hosting, deployment, security maintenance and backup recovery.
  • ! Payment-provider fees and any development or configuration work.
  • ! Staff training and commercial support when needed.

Tendenci is an association website project as much as an event-registration purchase. Its useful connection is between the member record, the price that person should pay and the event activity recorded afterward.

For self-hosting, name the person or provider responsible for upgrades, backups and payment setup before committing. Evaluate the working event journey alongside the operational cost of keeping the site available.
