Squid vs Varnish: What are the differences?

Squid: A caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Squid reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems, including Windows and is licensed under the GNU GPL; Varnish: High-performance HTTP accelerator. Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture.

Squid and Varnish can be categorized as "Web Cache" tools.

Squid and Varnish are both open source tools. Varnish with 908 GitHub stars and 216 forks on GitHub appears to be more popular than Squid with 560 GitHub stars and 202 GitHub forks.
