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:

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:

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.

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.

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.

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.

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.

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

Is it CPU, memory, or your app?
That lack of context is what slows debugging down.

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.

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.

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.

Angular fixed reactivity with signals.
Forms were still stuck in events, subscriptions, and guesswork.
Signal Forms bring everything into one model.

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.

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.

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.

Vibe coding gets your app deployed fast.
But in production, things can fail silently, slowly, and expensively.
If you’re using AI to code and not monitoring errors, performance, and queries, you’re missing vital warning signs.

Your monitoring stack shouldn't go down during a traffic spike. But with Prometheus, it can.
In our latest post, we explore what a production Prometheus setup actually costs - in infrastructure, engineering time, and peace of mind.
