Before you switch

Should you replace Vellum?

Why people stay 5

  • Side-by-side model testing makes prompt and provider changes easier to judge against identical cases.
  • Evaluation datasets turn subjective prompt iteration into repeatable checks before release.
  • Hosted endpoints let teams update LLM behavior without redeploying application code each time.
  • The visual canvas gives product specialists a practical way to contribute to application logic.
  • Production traces identify the configuration and model behind an individual output.

Why people switch 4

  • The extra platform layer can feel excessive for products built around one or two straightforward prompts.
  • Visual workflow definitions are less natural to review and merge than code stored in Git.
  • Execution volume and underlying model usage can make total costs difficult to forecast.
  • Advanced governance, support, and scale requirements push teams toward higher-priced or negotiated plans.
