Feedpushr is a powerful open source RSS feed aggregator able to process and send articles to third party services. And among these services, we have readflow.
To execute Feedpushr you have several possibilities:
Use Go to compile and install the binary:
$ go get -v github.com/ncarlier/feedpushr
$ feedpushr --log-pretty --log-level debug
Or download the binary from the source repository:
$ sudo curl -s https://raw.githubusercontent.com/ncarlier/feedpushr/master/install.sh | bash
$ feedpushr --log-pretty --log-level debug
Or use Docker:
$ docker run -d --name=feedpushr ncarlier/feedpushr feedpushr --log-pretty --log-level debug
You can also launch Feedpushr in “desktop mode” by clicking on the feedpushr-agent executable. Feedpushr will then be accessible from an icon in your taskbar.
You should be able to access the Feedpushr Web UI :

Go to the Outputs configuration page:

Click on the + button to add an output and choose the readflow component.
Configure the component as follows:
Alias: Enter a short description (ex: To my readflow).URL: Leave this field blank to use https://readflow.app or enter the API URL if you are using another instance.API KEY: Enter the incoming webhook token.
Activate the new output:

You can then import your OPML subscriptions into Feedpushr and see new articles in readflow.
