    Project mention: AI agent observability with OpenTelemetry and Grafana LGTM | dev.to | 2025-07-13

    Once data flows through the collector, the Grafana LGTM stack lets you explore:

  3. signoz

    SigNoz is an open-source observability platform native to OpenTelemetry with logs, traces and metrics in a single application. An open-source alternative to DataDog, NewRelic, etc. 🔥 🖥. 👉 Open source Application Performance Monitoring (APM) & Observability tool

    Project mention: Zero to observable with OpenTelemetry and SigNoz | dev.to | 2025-07-15

    This topic describes how you can enforce observability in a simple application using OpenTelemetry and SigNoz.

  4. langfuse

    🪢 Open source LLM engineering platform: LLM Observability, metrics, evals, prompt management, playground, datasets. Integrates with OpenTelemetry, Langchain, OpenAI SDK, LiteLLM, and more. 🍊YC W23

    Project mention: AWS open source newsletter, #207 | dev.to | 2025-02-27

    I have been spending a lot of time exploring AI Coding Assistants like Amazon Q Developer to see how they can help open source developers, and Ricardo Tasso came up with a great example in how he is using Q Developer to generate deployment configurations for Kubernetes. He has written this up in his post, Creating Deployment Configurations for EKS with Amazon Q so go check it out (you can get started with Amazon Q Developer for free by registering your Builder ID here). Langfuse is an open source LLM engineering platform that helps teams collaboratively develop, monitor, evaluate, and debug AI applications. AWS Community Builder Matsuda shows you how you can deploy this, using CDK to make it simple. If this sounds like something you are interested in, go read the post Self-Hosting Langfuse v3 on AWS Using CDK.

  5. hyperdx

    Resolve production issues, fast. An open source observability platform unifying session replays, logs, metrics, traces and errors powered by Clickhouse and OpenTelemetry.

    Project mention: Show HN: ClickStack – open-source Datadog alternative by ClickHouse and HyperDX | news.ycombinator.com | 2025-06-05

    It would have even much better if the link was pointing to https://github.com/hyperdxio/hyperdx the actual source code.

    Because right now without the message on HN here, I wouldn't know what "open source observability stack" meant when the webpage does not explain what HyperDX is, nor does it provide a link to it or its code. I was expecting the whole thing "Open Source Datadog" to be ClickStack Repo inside Clickhouse Github. Which is not found anywhere.

    But other than that congrats!. I have long wondered why no one has built anything on top of Clickhouse for Datadog / New Relic competition.

    The Clickhouse DB opened up the ocean of open source "Scalable" Web Analytics that wont previously available or possible. I am hoping we see this change again to observability platform as well.
