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.
GetProofAnchor is a web evidence platform that helps individuals, companies, legal teams, auditors, journalists, and investigators capture and preserve online content as verifiable digital proof.
Instead of relying on ordinary screenshots, GetProofAnchor creates a tamper-evident evidence bundle that can include a screenshot, video, captured HTML, extracted text, metadata, cryptographic hashes, a verification report, DNS, TLS and timestamping records. The goal is to make it easier to prove what existed online at a specific moment in time — even if the page is later changed, deleted, edited, or disputed.
GetProofAnchor is designed for situations where online content matters: website changes, social media posts, public claims, misleading information, policy pages, competitor content, compliance records, online harassment, defamation, disputes, investigations, and regulatory documentation.
Each capture is built with integrity in mind. The evidence package can be independently reviewed, verified, and archived, helping users maintain a stronger chain of custody than a normal screenshot or browser printout. GetProofAnchor supports public web captures and is built with forensic-style documentation, auditability, and long-term verification in mind.
The platform is especially useful for lawyers, compliance teams, journalists, OSINT researchers, businesses, and anyone who needs reliable proof of online content before it disappears.

Langfuse is the other serious option in this category if you also want observability, evals and traces bundled with prompt management. Different scope, more setup, worth comparing honestly. - Source: dev.to / 7 days ago
Langfuse with Microsoft.Extensions.AI has an appealing story: update prompts without redeploying. A prompt fetches its config blob—model, tokens, temperature—which the code passes straight to the LLM. - Source: dev.to / 10 days ago
Langfuse is not a replacement for OpenTelemetry; it is a specialization layer built on top of it. Langfuse was engineered specifically for the unique telemetry needs of LLM applications. It acts as the semantic layer that OTel lacks. - Source: dev.to / 15 days ago
Langfuse and LangSmith exist for this. Use them. The 30 minutes you spend setting up observability saves you the 87 hours you'd spend debugging blind. - Source: dev.to / 28 days ago
In this project we will build a Python banking assistant agent using Strands Agents and make it observable and continuously evaluated using Langfuse — step by step. - Source: dev.to / 2 months ago
