There's lots of options! I use rssblue which does charge $5 a month but they make it easy to build the rss feed. There are other providers out there - I'll let the podcast ppl give suggestions on alternatives @npub19ha7...q0fa @ChadF and 33 others @StevenB @Sir Spencer, Wolf of KC 🐺 If you host your own website you can just upload the file yourself, grab an rss template, and point the tag towards where it was uploaded. That's the free DIY solution.
