The latest beta version of the Skylight gem adds support for Sinatra apps. We've gotten a lot of requests for Sinatra support, and we're happy to finally get it out to users for testing. Our Sinatra support is as good as it gets: we of course…
We've just released a new feature in Skylight that makes it easy to see where your Rails app is allocating memory. With new memory traces, you can reduce bloat and improve the response time of your app. Many performance monitoring tools treat requests as though they exist in…
Skylight learns how your app is performing by running an agent that instruments each request as it comes in. Built with efficiency in mind, our new Featherweight agent is now almost invisible, making it usable in even the most resource-constrained environments. Keeping our overhead low is extremely important, because it…
I recently spent a bunch of time deep diving into some mystery memory leaks in Ruby. They were persistent and annoying, though not devastating by any means—the kind we could get away with ignoring for a long while, but shouldn't. Spoiler alert: we let them hang out…
One of the coolest features of Rust is how it automatically manages resources for you, while still guaranteeing both safety (no segfaults) and high performance. Because Rust is a different kind of programming language, it might be difficult to understand what I mean, so let me be perfectly clear: * In…
Today we launched a fun and hopefully rewarding referral program for Skylight. Give $50, get $50 (inspired by our friends at Slack [https://slack.com/r/024l0tmu-02539w7p]). We're excited about being able to properly thank our enthusiastic users when they refer their friends. Much of our existing Skylight…
One "neat" (awful) feature in JavaScript is that it automatically changes dates to be in whatever timezone the user's computer is set to. This is great if you are building the online version of The Podunk Gazette and all your servers and users are in one…
Last week at GoGaRuCo, I talked about how Rust bends the performance/safety curve and enables a whole new generation of high-level programmers to become systems-level programmers. That tradeoff loomed large when we started building Skylight. We knew that we wanted to process high-fidelity traces of every request, in order…
Did you know that you can exchange money for goods and services? I did, but for some reason it still never occurred to me that I might be able to pay an artist to paint something just for me. That is, until my former co-worker Mischa McLachlan [https://twitter.com/…
We're excited to announce simpler, more predictable pricing for Skylight. Most of our customers have already been migrated to the new pricing, having shifted over the last month or so, and the responses have been overwhelmingly positive. TL;DR: Our old pricing wasn't amazing, and our…
