From the OOP:

Upvote RSS is a self-hosted project I've been working on that generates RSS feeds from social aggregation websites like Reddit, Lemmy, and Hacker News. You can subscribe to subreddits, Lemmy communities, and Hacker News while filtering to only the top posts. It will embed Reddit post media (videos, images, galleries), and you can optionally include parsed article content, AI-generated summaries, top comments, and more. Here are some of the features:

• Supports subreddits, Hacker News, Lemmy communities, and more to come
• Configurable filtering to dial in the right number of posts per day in your feed reader
• Embedded post media: videos, galleries, images
• Parsers to extract clean content and add featured images
• AI article summaries
• Estimated reading time, score, and permalinks to the original post
• Top comments
• NSFW filtering/blurring (Reddit only)
• Custom Reddit domain
• Light/dark mode for feed previews

Here's the GitHub link if you'd like to give it a spin:
