Crystal Survey 2017 Results
This year, the Crystal team launched the first official State of Crystal survey. We’re amazed by the fantastic feedback from the community.
We received 757 responses. Thanks a lot to everyone who took the time to respond! We tried our best to read through all of your comments and suggestions.
Without further ado, let’s take a look at the results.
How did you discover Crystal?

We wanted to learn how you discovered Crystal, and were surprised to find that a lot of you arrived at Crystal through search engines. On the other hand, we confirmed how important HackerNews and Reddit are to divulge young and small projects such as Crystal. Every now and then, someone from the community posts something interesting about Crystal, the post makes it to HN and Reddit front pages and in the next few days we notice a wave of new users and contributors on the different community channels.
Using Crystal

There’s a deeper story that we see in these numbers, which is consistent with what we hear in informal discussions about Crystal: the community is eager to start using the language in production, but is waiting for more concrete signals from the project. A considerable part of the community doesn’t even mind about that and trusts the ecosystem enough to take the leap.

Closing Thoughts
At the end of the survey, we asked: “Anything else you’d like to tell us?”
I’ll let some of the quotes speak for themselves:
Keep up the great work!
I love Crystal, and I want to use it more! Thank you!
Crystal is my first loved programming language :)
I can’t wait for the 1.0 release! Great job on everything so far.
I love you guys, keep it up! As a Rubyist with no prior experience with compiled languages, this was definitely and by far the easiest way to learn about them and get used to a strongly typed language.
Thanks to everyone who make Crystal and this survey possible <3
Happy Crystalling!
