Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Completion quality lags behind Copilot and Codeium. The privacy angle is the only differentiator.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“In a market with free alternatives (Codeium) and better ones (Copilot), Tabnine's position is uncomfortable.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“The privacy-first approach is admirable but the model quality gap is widening. Hard to see how they compete long-term.”
