Tailwind vs Bootstrap isn't a "which is better" question. It's "what are you building, and who is designing it?"
The 30-second version:
Two different philosophies
Bootstrap (5.x) gives you finished, styled components (navbars, modals, forms) plus the JavaScript to make them work. Tailwind (4.x) gives you single-purpose utility classes and no prebuilt components in its core.
Bundle size
Tailwind generates only the utilities you actually use, so production CSS stays small. Bootstrap ships a larger baseline stylesheet and JS bundle.
Customisation
Tailwind's design tokens (spacing, colour scales) live in CSS variables or config, so a custom look is the default path. Bootstrap themes through Sass maps and CSS variables, but heavy customisation means fighting the framework's defaults. Leave it unthemed and you get "the Bootstrap look".
Learning curve
Bootstrap is easier on day one and harder to bend later. Tailwind asks you to learn its vocabulary up front, but that knowledge carries from project to project.
So which one?
- Internal tool or MVP, no designer: Bootstrap gets you there fastest.
- Branded product where design matters: Tailwind, paired with a headless kit like shadcn/ui.
