Open-source LLMOps platform for prompt management, LLM evaluation, and observability. Build, evaluate, and monitor production-grade LLM applications. [#opensource](https://github.com/agenta-ai/agenta)
Unique: Combines prompt editing, LLM execution, and test set evaluation in a single unified UI, eliminating context switching between code editor, API client, and spreadsheet. The playground maintains full execution history and caches results, enabling instant comparison of variants without re-running expensive LLM calls.
vs others: More integrated than using OpenAI Playground + spreadsheet for tracking results; faster iteration than code-based prompt testing but less flexible for complex multi-step workflows; better for non-technical users than Langchain/LlamaIndex prototyping.
