Traceloop

Traceloop is an LLM reliability platform providing observability and continuous quality evaluation for language model applications, maintaining the open-source OpenLLMetry SDK built on OpenTelemetry standards; the company is joining ServiceNow. Who it's for: teams running LLM applications in production who need real-time monitoring of prompts, responses, and quality (faithfulness, relevance, safety) rather than only pre-launch testing. Strengths: building on OpenTelemetry (an established, vendor-neutral observability standard) rather than a proprietary tracing format is a real, meaningful technical choice for avoiding lock-in. SOC 2 and HIPAA certification plus on-premises/air-gapped deployment options support regulated-industry use cases directly. Weaknesses and limitations: the company being acquired into ServiceNow means product direction and standalone availability may change going forward — worth checking current status before committing long-term. No pricing is published on the main page. Real-world scenario: a team running an LLM application in production needs real-time monitoring for quality regressions (hallucination, unsafe outputs) as prompts or the underlying model change over time.
