| Fact | PromptLayer | PromptOps Manager |
|---|---|---|
| Evaluation | Evaluations can be triggered on new prompt versions, through the API, or ad hoc in the UI, and include historical backtests and side-by-side model comparisons. | The llm_judge assertion uses a second LLM call to grade a response and explain its reasoning. |
| Integrations | The LangChain integration exports traces through OpenTelemetry and supports cost and latency analytics, searchable metadata, and turning traces into evaluation datasets. | The documented LLM providers are OpenAI and Anthropic, with a fake provider for hardcoded responses. |
| Notable limits | Free includes 10 prompts and 10 playground runs per day, while webhooks are available on Team and Enterprise plans. | Team and workspace support with roles, a CLI, and GitHub Actions integration are listed as planned roadmap items. |
