https://redash.io/ Redash is a very similar feature set (if I understand correctly) and is open source, if anyone wants something hostable / ownable.

Thank you for mentioning Redash. Actually Redash’s features extend beyond QueryClips, as it allows to visualize the data, create dashboards, alerts and more.
@dpaola2 on the website you mentioned that you created QueryClips after being frustrated with the lack of simple, easy-to-use tools. I created Redash for the same reasons ;-) I just wonder, did you have the chance to evaluate Redash before creating QueryClips? :-)
