If you build Rails apps for a living, you don’t just want theory—you want real examples of effective debugging techniques for Ruby on Rails apps that actually save you at 2 a.m. when production is on fire. Rails is opinionated and powerful, but that also means bugs can hide in callbacks, background jobs, N+1 queries, and mysterious ActiveRecord magic. In this guide, we’ll walk through practical, battle‑tested examples of effective debugging techniques for Ruby on Rails apps, from using `byebug` and `pry` in gnarly service objects to tracking down memory leaks in long‑running Sidekiq workers. We’ll look at how to combine logs, stack traces, and performance tools to get from “something is slow” to the exact line of code that’s killing your response times. The focus here is on how experienced Rails engineers actually work: small, targeted experiments, clear instrumentation, and a toolkit of reliable debugging patterns you can reuse across projects.

Ever had a client swear “the site is slow”… while your server metrics look totally fine? CPU is chill, database is bored, and yet the homepage loads like it’s on dial‑up. Annoying, right? This is exactly where Lighthouse stops being a nice-to-have report and starts behaving like a very opinionated performance engineer sitting next to you. It doesn’t just tell you a score; it tells you where the browser is hurting. In this article, we’ll walk through three very real scenarios where Lighthouse turns vague complaints into clear, fixable problems: a JavaScript-heavy app that feels sluggish, a media-rich marketing site that looks pretty but crawls, and a “modern” single-page app that’s secretly blocking the main thread. No abstract theory. Just screenshots, metrics, and the kind of debugging trail you actually follow at 1:00 a.m. when production is on fire. If you’ve ever stared at a Lighthouse report wondering what to do first, this is for you.
