For the record; we consider the new authority on the Twtxt spec(s) going forward (has been for some years actually) to be implementers / primary maintainers of widely used clients. To date that is:

• yarnd @prologic@twtxt.net (me and others)
  
• jenny @movq@www.uninformativ.de
  
• tt @lyse@lyse.isobeef.org
  
• Timeline @darch@neotxt.dk / @eapl.me@eapl.me and others
  
• twtxt-el? – @andros@twtxt.andros.dev
  

Full list of supported and widely used clients can be found at https://twtxt.dev/clients.html – which I note a few above are actually missing from this page haha 🤣

Lol only i use discontinued client? (with patches but i’m lost sources so they “proprietary”)

@doesnm@doesnm.p.psf.lt LOL sorry which client are you using? 🤔 You can of course have a say! There aren’t that many active/used clients at the moment, and I forget which one you’re using 🤣🤣
