Reviewer scorecard
“One-line integration via proxy is genius. Change your base URL and instantly get logging, caching, and rate limiting.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“The proxy approach means minimal code changes. Cost tracking alone pays for itself when you have multiple models.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“As AI costs become a significant line item, observability and optimization tools like Helicone become essential.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
