- Extensive documentation with copy-paste examples
- Massive ecosystem: themes, templates, and admin dashboards
- Utility-first approach: compose any design from atomic classes
- JIT compiler for optimized, minimal CSS output
- Design token configuration via tailwind.config.js

I haven't shipped with Bootstrap in years. The last project I touched it on was a Rails admin around 2020, and the moment we ripped it out for Tailwind the velocity went up. Tailwind owns the modern stack: design tokens in config, JIT means no unused CSS, every framework supports it. Bootstrap still makes sense if your team writes server-rendered HTML and wants components-in-a-box with no compile step. For anything React, Vue, or Astro in 2026, Tailwind.
