What is Iconify

Wow, when it comes to Iconify I really have to rave about it! This thing is literally the ultimate boss of the icon world - 200,000+ open source vector icons, integrating all the famous icon libraries you can think of. It truly achieves that 'one framework to rule them all' feeling. What's amazing is it's completely open source, mostly using MIT license, which is incredibly friendly for commercial projects. What I admire most is its integration capability - major icon libraries like Material Icons, Font Awesome, Feather can all be called with a unified API here, no more headaches over different usage methods for different icon libraries.

Iconify FAQ

Q1: What's the difference between Iconify and other icon libraries?

The biggest difference is integration - Iconify isn't a separate icon library, but integrates all mainstream open source icon libraries into one platform with unified API calls. This way you don't need to learn different usage methods for different icon libraries.

Q2: Can commercial projects use it for free?

Yes! Iconify itself is MIT licensed and completely free. However, note that individual icons may have special license requirements, so it's best to verify before use.

Q3: How to use in React projects?

Install the @iconify/react package, then import the Icon component and specify the icon name through the icon property. For example: <Icon icon="mdi:heart" />

Q4: How's the icon loading speed?

Iconify uses smart caching mechanisms - after first load, icons are cached locally making subsequent usage very fast. Plus it supports on-demand loading, only loading icons you actually use.

Q5: Can it be used offline?

Yes! While online loading is default, Iconify also supports bundling icons into projects for offline use, or downloading SVG files for local use.
