I made a tool to convert a podcast's RSS feed into a webpage on which episodes can be easily streamed.
When you visit the page, you'll see a box in which to paste the RSS feed's URL:
Stick in a feed's RSS URL, and you get all available episodes in a list, reverse chronologically by release date:
Titles are links taken from the feed's metadata. Images are hotlinked from the host. Click-to-listen links bring up an embedded player:
The feed is stored in the page's URL, so it should be sharable. Currently no way to identify a given episode, but you should be able to do that with the episode title links, which should go back to the source.
Source code is released to the CC0 public domain, and can be found on Github, where you can also report bugs or help me make it better.
If you use it, let me know!
