Can Humanloop handle LLM evaluation workflows and report on quality, latency, cost and safety all in one place, or is it mostly just for prompt management?

“Historically, Humanloop was best understood as an integrated LLM evaluation and observability platform, rather than simply a prompt-management solution.”

“Dataset-based evaluations, LLM-as-a-judge, code-based evaluators, human review, factuality and relevance scoring”

“Track response latency, set thresholds and monitor performance”

“Track token usage and model costs, compare model configurations”

“Custom safety evaluators, bias and privacy checks, guardrails and alerts”

“The Humanloop platform was subsequently shut down on September 8, 2025. Its API and hosted service are no longer available.”
