What Parea AI is

Parea AI helps teams building LLM applications track experiments, observe production behavior, and gather human annotations. Its evaluation tools test performance over time, help debug failures, and compare changes to samples or models. Teams can collect feedback from end users, subject matter experts, and product groups, then comment on, annotate, and label logs for Q&A and fine-tuning. The Prompt Playground lets users compare prompts on samples or large datasets and deploy prompts to production. Parea can log staging and production data, run online evaluations, capture feedback, and track cost, latency, and quality. Those logs can also be used in test datasets and model fine-tuning. Listed SDKs are for Python and JavaScript/TypeScript; integrations include OpenAI, Anthropic, LangChain, Instructor, DSPy, LiteLLM, Maven, SGLang, and Trigger.dev. A free plan costs nothing and allows two team members, 3k logs per month with one-month retention, and 10 deployed prompts. Team costs $150 a month; Enterprise pricing is custom.

Who it suits

Parea suits teams developing production LLM applications that need evaluations, prompt testing, observability, or human review. Its documented on-premise deployment may suit organizations seeking to run frontend and backend services in their own environment.
