Storybook vs Jasmine
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

The metric that actually scales your invoice.
Storybook itself is free. Chromatic, the hosted visual-review service from the same team, is a separate paid product.

Strengths
- One artefact serves as documentation, visual baseline and interaction test.
- Design-system teams get a shared reference that designers can actually open.
- Rich addon ecosystem for accessibility, viewport and state manipulation.
- Self-contained: spies, clocks and matchers with no extra packages.
- Runs directly in a browser without bundling.
- Extremely stable API — old suites keep working.
Limitations
- Meaningful configuration and maintenance overhead; a neglected Storybook rots fast.
- Build times on large component libraries get long.
- Stories drift from production usage unless discipline is enforced.
- Feels dated; snapshot testing and modern mocking are absent or bolted on.
- Momentum has moved to Jest and Vitest, including within the Angular ecosystem.
- Weaker TypeScript ergonomics than newer runners.
Best for
Teams maintaining a design system or a large shared component library.
Existing Angular codebases and browser-native test setups.
