Reviewer scorecard
“First-party SDK with excellent TypeScript support. Tool use and streaming work flawlessly. The agent loop is well-designed.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Using the official SDK reduces risk of breaking changes. The agent patterns are production-tested by Anthropic themselves.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Anthropic's approach to safe, capable agents sets the standard. The SDK makes best practices the default path.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
