Agenta
Agenta is an open-source LLMOps platform designed to help teams build reliable AI applications with integrated prompt management, evaluation workflows, and system observability. It centralizes all prompts, experiments, traces, and evaluations into one structured hub, eliminating scattered workflows across Slack, spreadsheets, and emails. With Agenta, teams can iterate on prompts collaboratively, compare models side-by-side, and maintain full version history for every change. Its evaluation tools replace guesswork with automated testing, LLM-as-a-judge, human annotation, and intermediate-step analysis. Observability features allow developers to trace failures, annotate logs, convert traces into tests, and monitor performance regressions in real time. Agenta helps AI teams transition from siloed experimentation to a unified, efficient LLMOps workflow for shipping more reliable agents and AI products.

Arena.ai
Arena is a community-powered platform designed to evaluate AI models based on real-world usage and feedback. Created by researchers from UC Berkeley, it enables users to test and compare frontier AI models across various tasks. The platform gathers insights from millions of builders, researchers, and creative professionals to generate transparent performance rankings. Arena’s public leaderboard reflects how models perform in practical scenarios rather than controlled benchmarks. Users can compare models side by side and provide feedback that helps shape future AI development. It supports a wide range of use cases, including text generation, coding, image creation, and video production. By leveraging collective input, Arena advances the understanding and improvement of AI technologies.

AgentHub
AgentHub is a staging environment to simulate, trace, and evaluate AI agents in a private, sandboxed space that lets you ship with confidence, speed, and precision. With easy setup, you can onboard agents in minutes; a robust evaluation infrastructure provides multi-step trace logging, LLM graders, and fully customizable evaluations. Realistic user simulation employs configurable personas to model diverse behaviors and stress scenarios, and dataset enhancement synthetically expands test sets for comprehensive coverage. Prompt experimentation enables dynamic multi-prompt testing at scale, while side-by-side trace analysis lets you compare decisions, tool invocations, and outcomes across runs. A built-in AI Copilot analyzes traces, interprets results, and answers questions grounded in your own code and data, turning agent runs into clear, actionable insights. Combined human-in-the-loop and automated feedback options, along with white-glove onboarding and best-practice guidance.

LLM Scout
LLM Scout is an evaluation and analysis platform designed to help users benchmark, compare, and interpret the performance of large language models across diverse tasks, datasets, and real-world prompts within a unified environment. It enables side-by-side comparisons of models by measuring accuracy, reasoning, factuality, bias, safety, and other key metrics using customizable evaluation suites, curated benchmarks, and domain-specific tests. It supports the ingestion of user-provided data and queries so teams can assess how different models respond to their own real-world workflows or industry-specific needs, and visualize outputs in an intuitive dashboard that highlights performance trends, strengths, and weaknesses. LLM Scout also includes tools for analyzing token usage, latency, cost implications, and model behavior under varied conditions, helping stakeholders make informed decisions about which models best fit specific applications or quality requirements.
