This guide evaluates the tools still actively shipping in 2026 — PromptLayer, Langfuse, LangSmith, Agenta, Braintrust, and MLflow Prompt Registry — against a consistent workflow covering versioning, codeless deployment, pre-ship evals, A/B testing, production debugging, and non-technical editing. PromptLayer is highlighted for native A/B traffic splitting and non-engineer collaboration; Langfuse and Agenta for open-source self-hosting; LangSmith for LangChain ecosystem teams; Braintrust for eval-in-CI workflows; and MLflow for teams already on Databricks. Pricing and vendor status are included for each. ## Full article daily.dev links to this article rather than hosting it.
