Vellum — Structured System vs. Prompt Library

Vellum is an AI development platform for building, evaluating, and deploying AI features and workflows, with a visual orchestration builder for product and engineering teams. PromptFluent is the governance and standardization layer beneath that work -- a business-wide prompt library with approvals, role-based access, and adoption analytics. The pattern is agentic on top, governed beneath: Vellum can orchestrate complex flows while PromptFluent keeps the underlying prompts standardized, governed, and measurable.

Team features Enterprise capabilities

When Vellum May Be Enough

  • You are building AI product features for customers
  • You need advanced or agentic workflow orchestration
  • You need evaluation and deployment pipelines
  • Your primary users are product and engineering teams

When PromptFluent Makes Sense

  • You need to govern and standardize prompts across the whole organization
  • You want a ready business prompt library, not an orchestration builder
  • You need approvals, role-based access, and audit trails for non-technical teams
  • You want the governed layer beneath your agentic and orchestration tools
