Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“The Docker of LLMs. Pull a model, run it, use the API. Privacy, no cloud costs, works offline. Essential tool for any developer experimenting with local AI.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Local models still lag behind cloud models in quality. But for development, testing, and privacy-sensitive use cases, Ollama is the obvious choice. Free is hard to beat.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Local AI is the future for privacy and cost. As models get smaller and hardware gets better, Ollama becomes the default way to run AI. They are building the runtime layer.”
