I’ve been building an Elixir app to poll RSS feeds and pipe new entries to Discord.

Performance is rock solid, and it’s almost ready to release, I just need to tweak a few things (like free trial with no CC).

I have a very long to do list, and ultimately want to extend it with “change detection”, e.g. notify when an HTML element on a website changes.

All feedback is welcome

I've been using elixir to build an app that lets an administrator add new rss feeds, render the article titles and summaries to a single page, scroll through them and push the ones they like to a landing page as a collection to read later. Many of the sites I like don't have the conventional RSS "structure" so I have to modify my main parser and adapt it to the outliers. I'm curious, how do you adapt to feeds that don't fit the conventional RSS structure? I was thinking of just using an LLM to automate it as I keep using Claude AI to expedite the process.

Do you mean they technically have RSS, but they’re using slightly different fields? E.g. summary instead of description?

I’m using FastRSS[^0] with some lightweight pattern matching to convert them to an internal model. I get error notifications for mismatches, and just push a new pattern match to handle the outlier.

Longer term it could be interesting to get an LLM to write some Lua to parse JIT.

Cool, could also check out a unified App platform framework:
