Traceloop
AI observability and workflow platform for monitoring experiments and tracking model performance.
The go-to open-standards LLM observability layer for AI teams that want vendor-neutral traces and automated quality gates.
Traceloop — LLM observability and reliability platform built on OpenTelemetry.
Traceloop is an LLM-specific observability tool that traces prompts, responses, latency, and quality through its open-source OpenLLMetry SDK. The DB has both the pricing and price tier wrong — there is no $29/month plan; Traceloop offers a Free Forever tier (up to 50K spans/month) plus custom Enterprise pricing, making it freemium not paid. Acquired by ServiceNow in March 2026, the product remains focused on helping AI teams ship reliable LLM applications with automated CI/CD quality gates and real-time drift detection.
OpenTelemetry-native architecture and multi-language support (Python, TypeScript, Go, Ruby) make Traceloop the least lock-in-heavy LLM observability option on the market. The OpenLLMetry OSS library plugs into 25+ existing observability platforms, so teams with Datadog or Grafana already in-house can adopt it without a new SaaS dashboard.
The free tier's 24-hour data retention makes it impractical for real production debugging — you'll hit Enterprise (opaque, contact-sales pricing) with no self-serve paid middle tier. ServiceNow's 2026 acquisition also introduces roadmap uncertainty for independent users.
