Explicit, debuggable control over agent state and flow

Requires comfort with graph and state concepts
Paid platform and observability are separate products
Vellum pros and cons

Visual workflow builder lowers the barrier for cross-functional collaborators
Solid evaluation and testing tooling for pre-production quality gates
Multi-provider model support avoids lock-in
Pricing is opaque and sales-led, making budgeting hard
Not open source, and self-hosting is locked to Enterprise
Free tier is quite limited in credits, documents, and seats
