Sort:Used by Most Apps
opentracing-go
The original vendor-neutral distributed tracing API for Go, later folded into OpenTelemetry.
go-metrics
A Go port of Coda Hale's Metrics library for counters, gauges, histograms, meters, and timers.

Langfuse JS/TS SDK (@langfuse/client)
Universal JavaScript/TypeScript client for Langfuse: prompt management, dataset experiments, evaluation scores, and media uploads through one typed API.
pyroscope-nodejs
Continuous CPU and heap profiling for Node.js apps, exported directly to Grafana Pyroscope.
@grafana/alerting

memory_profiler
Line-by-line and time-based memory profiling for Python code, with a CLI and decorator API for tracking down leaks.
Symfony Stopwatch
A tiny PHP component for profiling code by timing named events and measuring memory usage
Laravel Pulse
Real-time application performance monitoring and dashboard for Laravel apps.
django-prometheus
Prometheus metrics middleware and instrumentation for Django requests, databases, caches, and models.
pprof

metrics
A lightweight, protocol-agnostic metrics facade for Rust, decoupling instrumentation from whatever exporter you plug in.
Django HealthCheck
Pluggable health checks for Django applications and their dependencies

dd-trace-py
Datadog's official Python APM client for distributed tracing, profiling, and observability.
InfluxDB Client Go
The official Go client SDK for writing and querying data on InfluxDB 2.x time-series servers.
