Overview

About Fallom

Fallom is an AI-native observability platform built from the ground up for teams developing applications with large language models (LLMs) and AI agents. In the complex world of AI operations, traditional monitoring tools fall short. Fallom provides the fundamental visibility needed to understand, manage, and improve AI-powered systems in production. It works by automatically tracing every LLM call, capturing essential data like the exact prompts sent, the model's outputs, any tool or function calls made, token usage, latency, and per-call costs. This end-to-end tracing is the cornerstone of AI observability. The platform is designed for engineering and product teams who need to move beyond simple logging to gain actionable insights. Its core value proposition is delivering comprehensive, real-time visibility into AI workloads, enabling organizations to optimize performance, control costs, troubleshoot issues quickly, and maintain compliance with enterprise and regulatory standards. With its OpenTelemetry-native SDK, integrating Fallom is a straightforward process, allowing teams to start tracing their applications in minutes and establish a foundational layer of observability for their AI initiatives.
