What is Agenta?
Agenta is an open-source LLMOps platform designed for building production-grade LLM applications. It helps engineering and product teams create reliable LLM apps faster by providing end-to-end tools for the entire LLMOps workflow: building with an LLM playground and evaluation capabilities, deploying through prompt and configuration management, and monitoring via LLM observability and tracing.
The platform offers a unified playground where teams can compare prompts and models side-by-side with complete version history. It provides automated evaluation with LLMs at scale, human evaluation integration for domain experts, and online evaluation for production applications. Agenta enables tracing of every request to find exact failure points, allows annotation of traces with team feedback, and can turn any trace into a test with a single click.
Agenta is built for developers, product managers, and domain experts working on LLM applications. It enables collaboration between technical and non-technical team members by providing a UI for experts to safely edit and experiment with prompts without touching code. The platform is model-agnostic and framework-agnostic, working seamlessly with LangChain, LlamaIndex, OpenAI, Cohere, and local models.
Key features include prompt management with version control, systematic evaluation processes, complete observability with cost tracking, and full API parity with the UI. The platform is MIT licensed open-source, allowing self-hosting and modification for commercial projects without restrictions.

Frequently asked questions about Agenta
What is Agenta?
Agenta is an open-source LLMOps platform that helps developers and product teams build reliable LLM applications. It covers the entire LLM development lifecycle including prompt management, evaluation, and observability. The platform provides tools for prompt engineering, evaluation, debugging, and monitoring of LLM applications.
Is Agenta free to use?
Yes, Agenta has a free tier with Unlimited prompts, 2 seats included, 20 evaluations per month, 5k traces per month, and 30 days retention period. The open-source version is also free and MIT licensed, allowing you to self-host it with no restrictions for commercial projects.
What frameworks does Agenta support?
Agenta is framework-agnostic and seamlessly integrates with LangChain, LlamaIndex, and any other LLM framework. It works with any model provider including OpenAI, Cohere, and local models, enabling prompt engineering and evaluation on any LLM app architecture such as Chain of Prompts, RAG, or LLM agents.
Can non-developers use Agenta?
Yes, Agenta empowers non-developers including product managers and domain experts to iterate on LLM application configuration, evaluate it, annotate it, A/B test it, and deploy it all within the user interface without touching code. The UI is specifically designed for experts to safely edit and experiment with prompts.
What types of evaluation does Agenta support?
Agenta provides three types of evaluation: automatic evaluation with LLMs at scale before production, human annotation where subject matter experts review results and provide feedback to AI engineers, and online evaluation for applications already in production. Both subject matter experts and engineers can run evaluations from the UI.
How does Agenta's observability work?
Agenta helps you understand what happens in production by tracing every request to find exact failure points. You can capture user feedback through an API with thumbs up or implicit signals, debug agents and applications with tracing to see what happens inside them, track costs over time, and find edge cases where things fail.
Can I self-host Agenta?
Yes, Agenta is open-source and MIT licensed, so you can self-host it, modify it, and use it in commercial projects without restrictions. The Enterprise plan also includes self-hosted deployment options with dedicated support for large organizations.
What is the difference between the free and Pro plans?
The free tier includes 2 seats, 20 evaluations/month, 5k traces/month, and 30 days retention. The Pro plan at $49/month includes 3 seats (up to 10), unlimited evaluations, 10k traces/month then $5 per 10k, 90 days retention, prompt management, custom workflows, and in-app support.
How does Agenta help with prompt collaboration?
Agenta organizes prompts for teams so subject matter experts can collaborate with developers without touching the codebase. Developers can version prompts and deploy them to production. The playground lets teams experiment with prompts, load traces and test sets, and test prompts side by side.
What happens when I find an error in production?
When you find an error in production, you can save it to a test set and use it in the playground. Agenta allows you to turn any trace into a test with a single click, closing the feedback loop. You can then annotate the trace with your team or get feedback from users and run evaluations to validate fixes.
