Most teams don't run a single language. They run Ruby on the backend, Next.js on the front end, a Go service for performance-critical work, and something else they inherited. Monitoring all of that shouldn't mean managing five different tools.

AppSignal's OpenTelemetry integration lets you bring observability to any OTel-instrumented app and see it all in one place.

One Tool, Any Stack

AppSignal already has native integrations for Ruby, Elixir, Node.js, Python, and front-end JavaScript. OpenTelemetry extends that to cover practically everything else:

• Go
• Java
• Laravel
• Next.js
• PHP
• Rust
• Symfony
• Vercel

If it emits OpenTelemetry signals, AppSignal can monitor it.

From OTel Signal to Root Cause

Connecting an OTel-instrumented app to AppSignal gives you the same core observability regardless of language:

• Why is my error rate spiking?
• Which part of my code is slowing down requests?
• Who's experiencing the issue right now?
• When did the problem first appear in my traces and metrics?

Trace Every Request End to End

AppSignal's Trace Timeline lets you follow a request from start to finish. Search and filter by attributes, identify slow spans, and pinpoint the exact bottleneck affecting your users.

Dig Into Historical Performance

AppSignal's Time Detective lets you move from a high-level health overview to a detailed performance snapshot in a couple of clicks. Useful for investigating incidents after the fact, or understanding gradual degradation over time.

Alerts That Give You Context

AppSignal's smart alerts notify you in Slack, MS Teams, or wherever your team works, with enough context to go straight to the root cause. Less time triaging, more time fixing.

Built for Depth, Not Just Ingestion

A lot of monitoring tools accept OpenTelemetry data and stop there. AppSignal goes further, applying the same interpretation and insight layer you'd get from a native integration. We support traces, metrics, and logs, with distributed tracing on the roadmap.
