Langfuse is an open-source LLM engineering platform designed to empower developers by providing insights into user interactions with their LLM applications. We offer tools that help developers understand usage patterns, diagnose issues, and improve application performance based on real user data. By integrating seamlessly into existing workflows, Langfuse streamlines the process of monitoring, debugging, and optimizing LLM applications. Our platform's robust documentation and active community support make it easy for developers to leverage Langfuse for enhancing their LLM projects efficiently. Whether you're troubleshooting interactions or iterating on new features, Langfuse is committed to simplifying your LLM development journey.

Amazon BedrockBased on our record, Amazon Bedrock should be more popular than Langfuse. It has been mentiond 72 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Langfuse is the open-source standard for LLM observability. It traces every LLM interaction โ prompts, completions, latency, token usage, cost โ and provides the tooling to debug, evaluate, and optimize LLM applications in production. Think of it as "Datadog for LLM calls" with a focus on prompt engineering workflows. - Source: dev.to / 18 days ago
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / 29 days ago
Gateway or proxy attribution. A reverse proxy in front of the model-provider API records the request, computes the cost, and exposes per-customer breakdowns. Open-source options include Helicone, LiteLLM, Langfuse, and OpenLLMetry. Hosted equivalents serve as the AI cost observability layer for teams that want centralized visibility: LangSmith, Datadog LLM Observability, Arize Phoenix.

Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline โ the metadata.userId pattern is the universal part. - Source: dev.to / about 1 month ago
Harness-level logging and traces. If you're running agents through an orchestration layer - LangChain, LangGraph, CrewAI, or similar - ship traces to an observability tool. Langfuse is a solid open-source option for LLM tracing: every tool call, every input/output, timestamped. That's your audit trail. You really appreciate when the investigation "what did the agent do and when?" takes less than a minute. - Source: dev.to / about 2 months ago
Foundation Models (FMs): Large pre-trained transformer models available via Amazon Bedrock: AWS Nova, Claude (Anthropic), Llama (Meta), Amazon Titan (text, embeddings, image), Jurassic-2 (AI21 Labs), Stable Diffusion (Stability AI). Select FMs based on task, latency, cost, and token limits. - Source: dev.to / 2 months ago

"But we already have an LLM gateway." If your team routes AI traffic through a gateway like LiteLLM or AWS Bedrock, you already have token-level usage data. But if your engineers are on coding plans โ Claude Team/Max, OpenCode Go, GitHub Copilot seats, ChatGPT Codex โ the LLM calls bypass your gateway entirely. You lose visibility into the interesting stuff: how many tool calls per session, prompt sizes, which... - Source: dev.to / 3 months ago
To understand why this certification matters, it helps to look at how we got here. About three years ago, when ChatGPT/OpenAI took the world by storm with the GenAI and LLM revolution, we saw AWS flagbearer GenAI service Amazon Bedrock being used primarily for setting up chatbots, statbots, and AI assistants with Retrieval Augmented Generation (RAG) enabled and basic agentic setups. Those were small-scale and... - Source: dev.to / 3 months ago
