About
Parea AI is a comprehensive evaluation and observability platform designed specifically for teams building production-ready Large Language Model (LLM) applications. It serves as a centralized hub for tracking experiments, monitoring production logs, and managing human feedback loops. By providing deep visibility into how AI models perform in real-world scenarios, Parea helps developers identify regressions, optimize prompt performance, and ensure that their AI systems are meeting quality benchmarks before and after deployment. The platform acts as a dedicated environment for the entire lifecycle of an AI feature, from initial prototyping to continuous improvement in the field. The platform features a robust suite of tools including a Prompt Playground where users can iterate on multiple prompts against large datasets. It integrates seamlessly with existing workflows through simple Python and JavaScript SDKs that automatically trace LLM calls for providers like OpenAI and Anthropic. Users can run evaluations to answer critical questions about model upgrades or performance changes, using automated metrics to detect when specific samples regress after a change. Additionally, Parea supports human-in-the-loop workflows, allowing subject matter experts and product teams to annotate, comment on, and label logs, which can then be converted into high-quality datasets for fine-tuning. Parea is ideally suited for software engineers, AI researchers, and product managers at startups or enterprises who are moving beyond simple prototypes to robust production environments. It is particularly valuable for teams working on complex RAG pipelines or agentic workflows where latency, cost, and output quality are critical metrics. Industries ranging from legal tech to software automation utilize the tool to maintain high reliability in their LLM outputs, ensuring that model behavior remains consistent even as underlying providers update their algorithms. What distinguishes Parea from generic observability tools is its deep integration into the LLM development lifecycle and its specialized focus on evaluation. Features like "auto-trace" for LLM clients and the ability to create domain-specific "self-improving" evals offer a specialized environment that generic logging services cannot match. Its native support for major frameworks like LangChain, DSPy, and LiteLLM ensures that it fits into modern AI tech stacks without significant overhead, while its status as a Y Combinator-backed company reflects its position as a dedicated monitoring solution for the next generation of AI-driven applications.

FAQs
Which programming languages does the Parea SDK support?
Parea provides native SDKs for both Python and JavaScript/TypeScript. These SDKs allow for automatic tracing of LLM calls and easy integration of evaluation functions into your existing codebase with minimal configuration.
Can I use Parea to collect human feedback on my AI outputs?
Yes, the platform includes a human review queue where subject matter experts and product teams can annotate, label, and comment on logs. This feedback can be used for quality assurance or to build datasets for fine-tuning models.
What LLM providers are compatible with Parea?
Parea offers native integrations for major providers and frameworks including OpenAI, Anthropic, LangChain, DSPy, and LiteLLM. It also supports specialized tools like Instructor and Trigger.dev to streamline development.
Is there a way to test prompts before deploying them?
Parea features a Prompt Playground where you can tinker with multiple prompt versions on specific samples or large datasets. Once you identify a high-performing prompt, you can deploy it directly into production through the platform.
Does Parea offer options for data security and on-premise hosting?
Yes, for organizations with strict compliance requirements, the Enterprise plan offers on-premise and self-hosting options. It also includes SSO enforcement, custom roles, and dedicated support SLAs for added security.
