RSS-proxy allows you to do create an ATOM or JSON feed of any static website or feeds (web to feed), just by analyzing just the HTML structure. Try the demo. It is an alternative UI to feedless with a reduced feature set. If you want advanced features like fulltext feeds, aggregation, persistence, authentication and others, checkout feedless

• Web to Feed
• Feed to Feed: pipe existing native feeds through rss-proxy to filter them
• Filters
• Self Hosting

If you look for features below, you have to use feedless, the successor of rss-proxy

• Feed Aggregation
• Authentication and multi-tenancy
• JavaScript Support (prerendering)
• Fulltext Feeds and other content enrichments
• Persistence
• CLI
• GraphQL API
• Plugins

If you have docker or podman installed, do this

docker pull damoeb/rss-proxy:2.1
docker run -p 8080:8080 -e APP_API_GATEWAY_URL=https://foo.bar -it damoeb/rss-proxy:2.1

APP_API_GATEWAY_URL is your outfacing url, which will be used as host for feeds you create.

Then open localhost:8080 in the browser.

If you are interested in running the first prototype, this is how you do it.

docker pull damoeb/rss-proxy:1
docker run -p 3000:3000 -it damoeb/rss-proxy:1

Then open localhost:3000 in the browser.
