Jest alternatives
16 other tools do this job. Which one is right depends on why Jest is not working for you — so start from the reason, not the list.
Why teams leave Jest
- Native ESM support remains awkward, and the Babel transform layer is a recurring configuration tax.
- Noticeably slower than Vitest on large suites.
- jsdom is not a browser; subtle DOM and CSS behaviour differs from reality.
Worth saying: Jest is genuinely strong at this — everything in one dependency, with defaults that work for most projects on day one. If that is the part you rely on, switching may cost more than it saves.
If cost is the problem
Cheaper than Jest at the entry point, or free outright.
Vitest
Unit & Component
Vite-native test runner with instant watch mode and a Jest-compatible API.
Mocha
Unit & Component
Minimal, unopinionated Node.js test runner you assemble to taste.
Jasmine

Behaviour-driven JavaScript testing framework with no external dependencies.
AVA

Concurrent Node.js test runner that isolates every file in its own process.
Everything else in Unit & Component
Ranked by how widely adopted they are. Compare any two to see the differences that matter.
Behaviour-driven JavaScript testing framework with no external dependencies.

Query the DOM the way a user would, not the way the framework does.
The modern .NET testing framework, and the one Microsoft's templates default to.
Ruby's behaviour-driven testing framework with an exceptionally readable DSL.
