I tried Apollo Optics - horrible brand name BTW, everyone I mention it to here in Germany thinks of the eyeware retailer - and while it was easy to integrate and nice to look at, it provided little actual value compared to existing tools in the same space of performance monitoring.

When I tried it, the query execution view also wasn't aware of DataLoader usage. That meant, that once we started optimizing our queries, it looked like many slow parallel queries, which meant that you had to guess what was already optimized, and what wasn't.
We're committed long term to Meteor and Apollo both, and view both technologies as critical to the long-term success of the company. Apollo originated as a project to improve the internal data system of Meteor, but we saw that it was useful in a wider context. Today you can use Apollo with Meteor or with any other JavaScript or native mobile technology.
