AppSignal

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…

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. Tarun Singh explains 👇 blog.appsignal.com/2026/04/01/wha…

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. blog.appsignal.com/2026/03/26/mon…
