tendenci open source v15.x

Major Release: Tendenci v15.0 — Open Source Association Management Software (AMS)
Released March 30, 2024. As of October 8, 2025, Tendenci is currently on version 15.3.7.

A Heartfelt Thank You 🩵🐾`
First and foremost, we want to thank the GitHub community and all the developers contributing to the Tendenci project—your Tendenci project! Together, we continue to empower nonprofits and associations worldwide with open source freedom and transparency.

If you host your Tendenci website with us—great news: your site has already been upgraded. Yeii! 🤓🐾

Real People, Real Work 👩🏻‍💻🐾
It took a lot of planning and teamwork to cross the finish line for this major upgrade, and it wasn’t performed with Artificial Intelligence. It was done by real people—in particular, a strong programmer and developer who has passionately maintained the Tendenci repository for more than 15 years. Our team proudly celebrates our Chief Programmer, Jenny Qian, who continues to be a pillar of the Tendenci community.

Our Commitment to You 🐾
As always, we remain dedicated to providing our hosted clients with secure, scalable, and affordable managed hosting services in our AWS private cloud. Compared to other AMS platforms, our hosting stands out—
✅Security and privacy first

✅No per user or admin fees
✅No license fees
✅ Upgrades are included in the hosting plan that best suits your association

If your association is exploring a new Association Management System (AMS), we’d love to connect. Contact us for a free consultation and demo!

Check out some of the cool stuff in the latest Tendenci version bump!

1️⃣ Region filter in the Memberships Member Quick List Report. Finding members just got easier with the new region filter option, thanks to the brilliant suggestion from @rob-hills!

2️⃣ Streamlined Event Registration Add-ons: We’ve enhanced the event registration process by removing checkboxes, adding helpful text, and automatically clearing quantities after processing. Woof woof!

BECAUSE PER USER AND ADMIN PRICING ENCOURAGES YOU NOT TO GROW YOUR ORGANIZATION

Ed Schipul and Tendenci

At Tendenci we don’t believe in charging by the user or admin. Tendenci is built on the concept of distributed authoring. There are multiple people on your board and many committee chairs. Shouldn’t each leader in your organization have the ability to post their own articles and manage their own events? Certainly! This sets us apart from other AMS options in the market, as we do not charge any admin or user fees because we want you to grow.

Leverage Tendenci, the only Open Source software solution that enables you to populate your CRM with prospective members, industry contacts, supporting partners, and existing members without worrying. Achieve maximum engagement through your Tendenci website, which offers affordable and transparent AMS options – specifically tailored for Non-Profits and Associations around the world.

Twitter Embed on your Tendenci site

Hi, Tendenci Community! If you’ve noticed your Twitter feeds not working with the message “Nothing to see here – yet,” it’s mostly due to a browser issue. To fix it, ensure you’re not blocking third-party tracking on your preferred browser to see your tweets feed on your Tendenci site. ????

Join us on Fosstodon to support blockchain social media! We’re exploring other blockchain social networks too. See you there! ????

Are your users having issues with reCAPTCHA?

reCAPTCHA image from Google

Seems like there are occasions when our hosting clients are experiencing trouble on their Tendenci site due to reCAPTCHA. This doesn’t necessarily mean it is a Tendenci software problem but rather a Google issue. It is a service provided by Google to protect websites from automated bots and spam. If you are experiencing issues such as your users having difficulty completing the verification process or encountering errors on your Tendenci site, it is typically related to the Google reCAPTCHA service.

Our suggestion is the following: Make sure the browser is up to date and try disabling extensions. Here is an article with more details https://www.businessinsider.com/guides/tech/chrome-recaptcha-not-working.

If you haven’t already, get in touch with us so our team can set up reCaptcha V3 on your Tendenci website to better protect your site against spam, and at no cost. If you continue to run into issues, please don’t hesitate to contact us via our support team for further assistance.

Stay groovy,
