Humanloop Freemium

Humanloop is an LLM evaluation and observability platform that helps teams build reliable AI products. It combines prompt management, human feedback, and automated evaluation in one workspace.

With Humanloop, product and engineering teams can test prompts against real datasets, score outputs with human reviewers or AI evaluators, and monitor quality in production. This closes the loop from prototype to trustworthy deployment.
