Reviewer scorecard
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“The feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
