Both are excellent. The right choice depends on your timeline and design goals.
Pick Bootstrap When
- You need a complete UI in hours, not days
- You're building admin panels, blogs, or dashboards
- You want components (modals, navbars) out of the box
- Design customization is secondary to speed
Pick Tailwind When
- You have a specific design system or Figma mockup
- You want pixel-perfect control without writing CSS files
- You're in a React/Vue component workflow
- Bundle size matters and you'll purge unused classes
This blog uses Bootstrap because I shipped it in an afternoon. My SaaS uses Tailwind because the brand matters.
