To me, 41 stars in 6 weeks sounds quite good :-) There are some big successes on Github, but 99% of the projects doesn't get 5 stars in a year. Admittedly this one has much better information and website.
I think there's just a lot of frameworks in that space, many of them mature and backed by big companies, so it'll be hard to attract people...
In that sense, I think it's good that you immediately explain what the advantage of 码咖 is. That's the first thing I'd ask myself. The usage instructions are also important and present.
