Traceloop builds an LLM reliability platform that monitors, tests, and traces production model outputs. Its core stack includes the OpenLLMetry SDK and Traceloop Hub, a smart proxy for LLM calls. The company said in March 2026 that it is joining ServiceNow, and its technology will become part of ServiceNow's AI Control Tower.

Traceloop primarily focuses on the technology industry, specifically in the field of artificial intelligence and machine learning, providing monitoring solutions for large language models (LLMs).
Traceloop operates in the LLM observability market, where it faces competition from several notable companies:
Helicone: Helicone is a strong competitor that offers a user-friendly experience with features such as one-line integration, built-in caching, advanced cost tracking, and enhanced security. It supports a broader range of integrations and programming languages without requiring an SDK, making it more accessible for users who may not have extensive coding experience. In contrast, Traceloop is designed for code-first users, focusing on execution tracing and providing a standard toolset for evaluation and tracing, but it requires more configuration and coding.
Langfuse: Langfuse provides observability tools specifically tailored for LLMs, integrating with frameworks like Langchain. It offers features such as prompt management and response evaluation, which can enhance the monitoring capabilities for users.
Langsmith: Similar to Langfuse, Langsmith integrates with Langchain and provides a feedback loop for evaluating responses. This integration allows for a more streamlined monitoring process for LLMs.
Datadog: While primarily known for infrastructure monitoring, Datadog also offers LLM observability features. However, its capabilities are somewhat limited to OpenAI integrations, which may not be suitable for all users.
Phoenix (by Arize): Phoenix is another competitor that focuses on LLM observability, providing unique features that cater to specific monitoring needs.
Traceloop's main advantage lies in its OpenLLMetry framework, which allows users to collect traces from various LLM providers and frameworks, publishing them in OpenTelemetry format. This flexibility helps avoid vendor lock-in, a significant advantage in the observability space.
