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.

ScrapeOps's answer:
ScrapeOps helps developers build and operate web scrapers faster. Unlike many AI scraping tools that act as black boxes, ScrapeOps focuses on developer-first workflows with inspectable code, proxy infrastructure, monitoring, scheduling, and AI-powered scraper generation. Our newest product, ScrapeOps AI Scraper Generator, uses a schema-based approach to generate scraper code and then AI scores how correctly the scraper ran, helping developers understand output quality before using the data.
ScrapeOps's answer:
Most scraping platforms focus on either infrastructure or extraction APIs. ScrapeOps combines both. Developers get proxies, anti-bot tools, monitoring, scheduling, debugging tools, prebuilt scraper examples, and AI-assisted scraper generation in one platform. We prioritize transparency and ownership, so developers receive code they can inspect, modify, and deploy within their own workflows instead of being locked into a proprietary extraction system.
ScrapeOps's answer:
ScrapeOps is built for developers, data engineers, startups, SaaS companies, AI teams, researchers, and businesses that rely on web data. Typical users include teams building price monitoring tools, lead generation systems, market intelligence platforms, ecommerce analytics products, AI training pipelines, and large-scale web scraping infrastructure.
ScrapeOps's answer:
ScrapeOps started after seeing how much time developers spend rebuilding the same scraping infrastructure over and over again. Building a scraper is only a small part of the challenge. Keeping it running through site changes, JavaScript rendering, anti-bot systems, proxy failures, and data quality issues is where most teams struggle. ScrapeOps was created to reduce that operational burden and help developers get from idea to reliable production scraping faster.

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 / 3 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 / 6 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 / 11 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 / 23 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
