You have lots of options when choosing MMS or AMS. From Wild Apricot to Member Clicks, or Personify - all viable options. But if you need to scale to hundreds of thousands of members, have recurring memberships, organizational memberships and need full features of seasoned large scale enterprise AMS, it’s possible you might hit some limits with new kids on the block. Proprietary vendors are companies first and communities second. Tendenci is community first, and yes, there is a small company behind it. It’s just grown far bigger than we were expecting, and given it started in 2001, when you switch from proprietary solution it's an upgrade!

Feel free to take the demo site for a spin! Every site looks completely unique using Bootstrap themes. No long term contracts. Access to all of YOUR data at any time. Full access to source code. Everything under YOUR domain name. With Tendenci, you can self-host, host with us, leave whenever you want. If Tendenci isn’t the right AMS to manage YOUR memberships, you are free of constraints!

  • My 9 year old nephews drawing of stars
    I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: over 1 year ago
  • What are the best resources to explore space from my computer?
    Celestia was something I played with before. Pretty interesting. Source: over 1 year ago
  • Lunar Occultation of Mars
    Celestia looks as though it would do it. Source: over 1 year ago
  • Tips to visualize Apollo 17 trajectory
    I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
  • Help rediscovering a certain night sky exploration program?
    Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago
