rsstodolist is a service to build RSS feed, hosted at https://rsstodolist.eu/.
You can deploy the server code on your own server (https://github.com/paulgreg/rsstodolist-node-server) to host your private instance, for more privacy and reliability.
This is the rsstodolist add-on for Firefox and Chrome, allowing to add URL to a RSS feed, available on the Mozilla Add-on repository and Chrome Web Store.
It uses the Web Extension API which make it compatible between Firefox and Chrome.
