Overview

About Fallom

Fallom is an innovative AI-native observability platform designed specifically for the unique demands of monitoring and optimizing Large Language Model (LLM) and AI agent workloads in production environments. As organizations progressively incorporate intricate AI chains into their core applications, traditional Application Performance Monitoring (APM) tools often prove inadequate, lacking the necessary granular, semantic visibility to manage these non-deterministic systems effectively. Fallom bridges this critical gap by providing end-to-end tracing for every LLM call, capturing vital data points such as prompts, outputs, tool calls, token usage, latency, and cost per call. This comprehensive visibility empowers engineering, DevOps, and product teams to transform opaque AI operations into transparent, debuggable, and cost-controllable processes. Utilizing a single OpenTelemetry-native SDK, Fallom allows teams to instrument their applications swiftly, enabling real-time monitoring, expedited debugging of agentic workflows, and accurate attribution of AI spending across various models, teams, and customers. Additionally, Fallom ensures compliance with evolving regulations, such as the EU AI Act, by offering enterprise-grade audit trails essential for regulatory adherence.
