#tracing

LatitudeNew

Open-source observability for AI agents that doesn't just show you where an agent failed in production — it can open a pull request with Claude Code or Cursor to fix it.

UptraceNew

A tool that shows engineers exactly which part of their app is slow or broken, by collecting traces, metrics and logs from the code in one place — built on the free, open OpenTelemetry standard instead of a proprietary agent.

TraceLLMNew

An observability tool that traces prompts, spans, tokens, errors and model calls once your AI app is in production.

MapleNew

An open-source observability platform — traces, logs, metrics and browser session replay in one tool, built on OpenTelemetry so you're not locked into a proprietary agent.

HyperDX

A free, open-source observability platform that unifies logs, metrics, traces, errors and session replays in one searchable interface — a self-hosted alternative to Datadog.

Dash0

An observability platform built entirely around the open OpenTelemetry standard, so your monitoring data isn't locked into one vendor.

Retrace

A debugging tool for AI agents that lets you rewind a failed run to the exact step that broke, change one thing, and replay it — so you can actually prove a fix worked instead of just hoping it did.

Laminar

A dashboard that shows you exactly what your AI agent did, step by step, when it fails — every tool call, every sub-agent, every LLM response — instead of leaving you to guess from a wall of logs.

SigNoz

Open-source observability platform that unifies traces, metrics and logs in one OpenTelemetry-native tool, self-hosted or cloud.

Honeycomb

Observability platform for debugging production systems with distributed tracing, BubbleUp anomaly analysis, and AI-assisted querying.

Highlight.io

Open-source fullstack monitoring: session replay, error tracking, logging and tracing in one self-hostable platform.

GreptimeDB

Open-source observability database unifying metrics, logs and traces: SQL and PromQL, written in Rust, object-storage native.
