What Tendenci is
Tendenci is open source association management software for nonprofits and associations. Its features cover membership administration, including corporate membership updates and auto-renewal fixes, as well as event registration. Release notes also describe donation forms, payment options, regional tax settings, newsletter enhancements, and directory improvements. Organizations can download the code and work with a Python/Django developer to customize it. Tendenci is available as self-hosted software, and the maker offers managed hosting in its AWS private cloud, with upgrades included in the hosting plan. The maker says hosting has no license fees or per-user or per-admin fees. Hosting safeguards it describes include SSL encryption, application isolation, AWS VPC controls, malware scanning, penetration testing, and auditing. Site superusers can use SQL Explorer to query site data and download results as CSV. The open-source software is free; hosting and implementation are separate services. Tendenci v16 requires Django 5.2 LTS and drops support for Python 3.8, Python 3.9, and PostgreSQL 13.
