AI Analysis

●●SolidSolve My ProblemShip It

Swap Vapi and Retell with one line—no app rewrites needed.

Strengths

•Typed error hierarchy (ProviderError, NotFoundError) consistent across all providers
•Runtime provider registry lets you switch without redeploying application code
•Custom provider support via defineProvider for proprietary voice platforms

Weaknesses

•Only two providers supported (Vapi, Retell) limits immediate usefulness
•Classic adapter pattern—useful but not architecturally novel
