Varnish software is a atentive and competent company which makes a excellent product that made a splash on the internet when it was introduced. The product is used all over the internet and at e.g. Fastly for their core offering. The product documentation is good (but consider getting one of their books if you want to do complicated things). Review collected by and hosted on G2.com.

Unfortunately, the mindshare of Varnish software in the Open Source world is diminishing. E.g. NGiNX is easier to start using as an ingress controller and cache server for new sites and once the infrastructure is set it gets hard to replace as requirements grow more complex. This might make it harder to recruit customers that way in the future.

The number of essential proprietary modules for varnish is also growing, and quite a few of them should perhaps be part of the base product and not even modules. Some features off the top of my head:

- Ability to sign s3 bucket requests

- Normalization of query parameters to reduce cache size where they are needed and can't just be stripped off

- A more extensive basic template that can, e.g., remove utm_ or fbclid and other common cruft that might crop up

A review of the VCL of some big sites might show other common patterns that should be possible to handle very easily in the standard VCL (depending on switches provided by the operator)

It's not that NGiNX handles these things out of the box but varnish can do better and deliver more value more quickly. Review collected by and hosted on G2.com.

The best thing about Varnish Software is its excellent HTTP accelerator service, which drastically increases the website's throughput, and its feature-rich web cache, which helps in scalability. Review collected by and hosted on G2.com.

The worst thing about Varnish is its documentation; it should be concise and to the point, so developers can easily read, understand and integrate it into their web. Review collected by and hosted on G2.com.

Varnish is simple to use and keeps data in the cache, allowing web platforms to be more helpful and reducing the amount of data transmitted. I haven't had any problem configuring this program.

Varnish has helped us to speed up our slow web servers. Our page visitors now enjoy reduced load times and they can handle any traffic with zero crashes and downtimes.

Working in the back-end, I appreciate their Transport layer Security feature, TLS which guarantees the protection of our internal servers from cyber attacks.

The Varnish Edge Cloud is up-to-date and allows our teams to harness the power of 5G with their virtualized CDN. Review collected by and hosted on G2.com.

There's little to mention on the cons of Varnish. I'd probably just request improvements on their intensive caching softtware model. It demands making plenty of changes to accommodate this. Review collected by and hosted on G2.com.
