“Skylight is a smart profiler for Ruby on Rails applications.”

As a further historical note that may interest HN users specifically, Skylight was the world's first production user of Rust (the Ruby gem they ship is written in it), dating back to well before Rust was even stable.

Which is mainly because Yehuda Katz (Rust core member) works at Skylight.

To be clear about the chronology here, wycats made the decision to go with Rust, then did a lot of work in Rust, then became a core team member. He chose Rust because of his needs in Skylight, not because he was already invested in Rust.

> Yehuda Katz will be known to many in the Rust community for his work on the initial design and implementation of the Cargo project. He is also a co-founder of Tilde, which has been using Rust commercially in their Skylight product for quite some time

For slightly more context, I wrote the first lines of Rust code for Skylight as a spike at the end of 2013, and joined the Rust core team more than a year later. :)

I was largely inspired by a blog post in June 2013 by Patrick Walton: Removing Garbage Collection From the Rust Language[1]

“Skylight is a smart profiler for Ruby on Rails applications.”

For clarity, we also support almost all Rack-based frameworks in Ruby (including Sinatra):

We should probably update our copy to clarify this point in the prominent places where it isn't already clear.
