AppSignal — error tracking and performance monitoring that just works.
When it’s broken
Something breaks. AppSignal shows you the errors, the slow queries, the deploys responsible. Dashboards ready from first deploy.
>Catch the error before users do
Every exception, every occurrence, with the backtrace and the deploy that shipped it. Grouped so you see patterns, not noise.

>See which query is running slow
Response times, throughput, slow endpoints, instrumented from your first deploy. Find the query killing your app.

>Follow the request across services
Every request traced end-to-end, which service, which call, which hop is the bottleneck.

Why it happened
The alert is just the symptom. AppSignal connects the error to the log, the log to the trace, the trace to the deploy. No tail -f required.
>Grep your logs without SSH-ing
Full-text search across every log you send us, with attribute filters and saved queries. No SSH, no config, no waiting.

>Watch logs stream live
Every log line, from every service, streaming as it happens. No refresh, no polling, no picking a server.

>Jump from trace to exact log line
Click an error. See the exact log lines that led to it. The correlation is done; the timestamps line up.

>Alert on whatever’s in the logs
Alert on any log pattern, error strings, warning spikes, anything you'd grep for. Catch problems before they reach the dashboard.

How to fix it
Stop the AI guesswork. AppSignal's MCP gives Claude, Cursor, or Zed the error, the trace, the deploy. Your AI writes a fix that fits.
>Feed the error into Claude
Plug Claude, Cursor, or Zed into AppSignal. Your AI assistant queries production directly, errors, traces, and deploys, on request.

>Let Cursor write the fix
AppSignal lives in your editor. Your AI pulls the error, writes the fix, opens the diff. You approve, or don't.

>Review a PR instead of debugging
Your AI drafts a pull request with the real cause behind it. You review the code, then merge.

>Find the deploy that broke prod
Every deploy marked, timestamped, and correlated with errors. When prod breaks, you know which ship caused it.

Give it to me straight, what’s going on with my app?
Datadog is complicated — you almost need a training course. With AppSignal you don’t. Everything you need is right in front of you. No information overload.
Daniel, VP of Engineering, Kairos
I don’t have time to grep through logs, what’s the root cause?
AppSignal picks up errors, issues and sends them back to us with a stack trace with each occurrence. I spend less time in the GCP logging systems.
Justin Tormey, CTO, Upside
Found the issue, how do I fix it or can AI just do it?
Connect Claude, Cursor, or Zed via MCP. AppSignal feeds your AI the error, the trace, the deploy, the code. Your AI knows what broke. So do you. No more vibe-debugging.
Just swapped Sentry with AppSignal for monitoring. I’m loving this product. Never seen a monitoring tool as fast as this one before.
Rainer, CEO, MemberKit
This isn’t a stack.
It’s a pile.
Just enough monitoring. All in one place. None of the mess.
One install · One invoice · All the context
Full-stack monitoring.
In a few lines of code.
A lot less effort than getting Datadog on the phone.

Previously, we were using Honeybadger, Skylight, and Datadog, but now we have all those apps in one: AppSignal, and that is awesome!
Oleg, Developer at Benuevo
Hey y’all, we’re back. Sentry was just chaos.
Matt, Developer at Supertape
The biggest benefit of using AppSignal is the native Elixir support. … AppSignal just knows how an Elixir app is structured and builds error tracking and performance monitoring around it.

We looked at Sentry, Datadog, and Honeybadger. AppSignal gave us everything in one tool for a fraction of the price.
Thilo Rusche, Developer at SportsKey
In New Relic, if you want more features, you have to upgrade… AppSignal’s pricing was easier to understand, and you get all the features for one price.
Devan Sabaratnam, Co-founder & CTO at HR Partner
Second to none support. It’s their developers themselves who are quickly and clearly answering any questions. It’s hard to overstate how nice this is.
