I am maintaining an open source simple aggregator:
<a href="https:&#x2F;&#x2F;github.com&#x2F;JARR&#x2F;JARR" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;JARR&#x2F;JARR</a>
and using it since more than 5 years. It has evolved a lot since...<p>It is possible to test it here:
<a href="https:&#x2F;&#x2F;jarr.herokuapp.com" rel="nofollow">https:&#x2F;&#x2F;jarr.herokuapp.com</a>
This instance is limited in resources...
It is deployable quite easily (a vagrant configuration file is also provided).
