Your LLM app’s lab, referee, and production dashboard

What it does

Agenta is an open-source LLMOps platform that bundles prompt engineering, systematic evaluation, and production observability into one workspace. Engineering and product teams can iterate on prompts in a side-by-side playground, version configurations across environments, and trace latency, cost, and usage once live.

The interesting bit

Instead of treating prompts as throwaway strings, Agenta versions them like code with branching and environment promotion. It also ships with more than twenty pre-built evaluators and OpenTelemetry-native tracing, so you are not starting from scratch on testing or observability.

Key highlights

• Interactive playground with side-by-side comparison across 50+ LLM models or custom providers
• Prompt version control with branching and environment promotion
• 20+ pre-built evaluators, LLM-as-judge support, and custom evaluator hooks
• OpenTelemetry-native tracing compatible with OpenLLMetry and OpenInference
• Available as a managed cloud tier or self-hosted deployment

Verdict

Worth exploring if your team is moving LLM features from prototype to production and needs shared prompt governance. Skip it if you want a lightweight, single-user prompt editor without evaluation or observability overhead.
