AppSignal

Good morning from Brighton Ruby, (thanks for organizing @andycroll!). We've got Dutch Stroopwafels (strope-waf-els), Brighton Rock, and we're giving away 3x @useTRMNL displays 😎

You picked your stack for how you work. Familiarity, speed, preference. None of that carries over when an agent writes the code. So we asked which framework an AI builds cheapest. Rails vs Django vs Laravel, every token counted. What we found: blog.appsignal.com/2026/06/17/vib…

The 2026 Rails Community Survey is open. 10 minutes, anonymous, and the results go back to the whole community. This year's focus: AI in Rails workflows: whether you're using it or not, your answer matters! railsdeveloper.com/survey/

When a Rails app is slow, it's easy to spend hours optimizing a view only to find that active_record is problem, turning our debugging question from "why is the app slow" to "which query is slow?". Introducing our guide to killing slow queries: blog.appsignal.com/2026/06/11/fin…

We now support @render 's metrics stream in AppSignal. Point it at your collector, and you get host metrics for your Render services plus automatic dashboards for HTTP, Postgres, and Key Value. We wrote up how it works: blog.appsignal.com/2026/05/22/mon… docs.appsignal.com/render/setup.h…

As systems grow, so does the number of APIs and services teams need to manage. @gkoos430 walks through building an API gateway with Koa, from request routing and auth to visibility into slow requests, errors, and upstream failures with AppSignal. blog.appsignal.com/2026/05/18/bui…

We make it easy to keep your data in Europe. Using Hatchbox to manage EU-based servers and AppSignal to keep monitoring data in the EU, you can run your app without sending data across borders. We wrote how to set this up: blog.appsignal.com/2026/05/07/dat…

More devs are self-hosting. But once you leave PaaS, you can lose visibility. Your host says CPU is spiking. It can't say which Express route takes 4.5s to respond. We wrote a guide on monitoring a Node.js app on Hetzner with AppSignal. blog.appsignal.com/2026/05/05/how…

Hatchbox lets you own your infrastructure. But you still need to know what's happening on your servers. We wrote a guide on setting up server monitoring for a Rails app with AppSignal, so you can know what's slow, what's breaking, what needs attention. blog.appsignal.com/2026/04/30/set…

Sidekiq jobs don't always fail loudly. They retry, slow down, and sometimes die before anyone notices. Then a user asks where their export is. That's where teams lose time. We wrote about how to monitor jobs and catch issues earlier with AppSignal: blog.appsignal.com/2026/04/28/mon…

PaaS was a great deal until it wasn't. But what changed? Costs went up, flexibility vanished, and debugging turned into a black box. We break down what's wrong with PaaS today, and what you can do about it with the help of tools like @hatchboxio blog.appsignal.com/2026/04/23/wha…

Is it CPU, memory, or your app? That lack of context is what slows debugging down. Learn how to monitor your VPS, track usage over time, and set alerts with AppSignal, all in one place. blog.appsignal.com/2026/04/21/mon…

We're excited to announce our partnership with @hatchboxio! Connect in a couple of clicks and monitor processes, databases, and cron jobs, with access to errors, performance, and host metrics. Hatchbox customers new to AppSignal get 10% off all plans. blog.appsignal.com/2026/04/20/app…

Your Django endpoint is slow. No errors. Logs look fine. Averages look fine. But response times are still slow, and you don’t know why. Jaume Boguña shows how to trace and fix it with AppSignal 👇 blog.appsignal.com/2026/04/14/tra…

Your app says everything is fine. Meanwhile, Celery tasks fail quietly in the background. Retries make it look like things recovered. Logs make it hard to see what went wrong. Nehemiah Bosire shows how to track Celery task failures with AppSignal 👇 blog.appsignal.com/2026/04/09/tra…

It's 3 am. Your app breaks. PagerDuty wakes you up. You're jumping between pods, logs, and guesswork, trying to figure out what’s wrong. There’s a better way. @deyyanl shows you how to quickly understand what's happening in Kubernetes with AppSignal 👇 blog.appsignal.com/2026/04/09/set…

Angular fixed reactivity with signals. Forms were still stuck in events, subscriptions, and guesswork. Signal Forms bring everything into one model. Sonu explains why this matters 👇 blog.appsignal.com/2026/04/09/sig…

Your Express route returns 200. But users still say it’s slow. Logs won’t tell you why. Patterns will. AppSignal shows which routes are slow, how often, and what’s causing it. Dimitrije explains how: blog.appsignal.com/2026/04/07/mon…

You can have all the metrics in the world. If no one gets alerted when things break, it doesn’t matter. Smart alerting notifies you before users do. Faith Kovi on setting AppSignal alerts that keep you on top of your app: blog.appsignal.com/2026/04/07/how…

Your Phoenix app feels fast until one endpoint slows it down. Slow queries, missing indexes, N+1 calls. If you're not monitoring your database, finding the bottleneck takes longer than it should. @AtomikSnowman shows how to debug slow Ecto queries: blog.appsignal.com/2026/04/02/deb…
