- A web server (Apache, Nginx, IIS)
- A minimum of 128MB of memory allocated to PHP

If Craft CMS needs to process very large images or dump very large databases, you might need to bump PHP’s memory allocation up to 256MB.

- GD or ImageMagick. ImageMagick is preferred.
- Multibyte String
- PDO MySQL Driver or PDO PostgreSQL Driver
Optional PHP Extensions

CP Browser Requirements

- Firefox 28 or later
- Safari 9.0 or later
- Internet Explorer 11 or later
- Microsoft Edge
- iOS: Safari 9.1 or later
