Trademark and Logo

The objective of the Varnish trademark policy is to encourage widespread use of the Varnish trademarks by the Varnish community while controlling that use in order to avoid confusion on the part of Varnish users and the general public, to maintain the value of the image and reputation of the trademarks and to protect them from inappropriate or unauthorized use.

The sections below describe what is allowed, what is not allowed, and cases in which you should ask permission. If you have any doubt, please contact us and a member of our team will be in touch with you shortly.

If you are aware of a breach or misuse of the Varnish trademarks in any way, we would appreciate you bringing this to our attention. Please contact us so that we can investigate this further.

The trademarks

Varnish Software AB owns the trademark "VARNISH". The trademark is registered in both word and logo form. This policy encompasses all marks, in word and logo form, collectively referred to as “Trademarks”. The trademark is registered in the US, EU and other jurisdictions, and has gained protection on many jurisdictions as an unregistered trademark through use. The fact that we own the trademark means that we also own the usage of it, hence no third party can use it without permission.

Permitted use

The main principle of usages of the Trademarks is that it requires prior written permission.

However, certain usages of the Trademarks are fine and no specific permission from us is needed. This is decided on case by case basis.

Community advocacy

Varnish is built by, and largely for, its community. We share access to the Trademarks with the entire community for the purposes of discussion, development and advocacy. We recognize that most of the open source discussion and development areas are for non-commercial purposes and will allow the use of the trademarks in this context, provided that the Trademark is used in a manner consistent with the Usage Guidelines below:

  • there is no commercial intent behind the use
  • what you are referring to is in fact Varnish. If someone is confused into thinking that what is not Varnish is in fact Varnish, you are probably doing something wrong
  • there is no suggestion (through words or appearance) that your project is approved, sponsored, or affiliated with Varnish or its related projects unless it actually has been approved by and is accountable to Varnish Software AB

Building on Varnish or for Varnish

If you are producing new software which is intended for use with or on Varnish, you may use the Trademark in a way which indicates the intent of your product. For example, if you are developing a system management tool for Varnish, acceptable project titles would be "System Management for Varnish" or "Varnish Based Systems Management". It is not permitted to use project titles such as VarnishMan, Varnish Management, ManVarnish, etc.

Furthermore, you may not use the Trademarks in a way which implies an endorsement where that does not exist, or which attempts to unfairly or confusingly capitalize on the goodwill or brand of the project or the companies.

Commentary and parody.

The Varnish trademarks are designed to cover use of a mark to imply origin or endorsement by the project. When a user downloads something called Varnish, they should know it comes from the Varnish project. This helps Varnish build a reputation that will not be damaged by confusion around what is and is not, Varnish. Using the Trademarks in your discussion, commentary, criticism or parody, in ways that unequivocally do not imply endorsement, is permissible. Anyone is free to write articles, create websites, blog about, or talk about Varnish -- as long as it is clear to everyone -- including people completely unfamiliar with Varnish -- that they are simply referring to Varnish and in no way speaking for Varnish Software AB, Varnish Software AS, or the Varnish project.

We reserve the right to review all usage within the open source community, and to object to any usage that appears to overstep the bounds of discussion and good-faith non-commercial development. In any event, once a project has left the open source project phase or otherwise become a commercial project, this policy does not authorise any use of the Trademarks in connection to that project.


Prior written permission from us is necessary to use any of the Trademarks under any circumstances other than those specifically permitted above.
These include:

  • Any commercial use.
  • Use on or in relation to a software product that includes or is built on top of a product supplied by us, if there is any commercial intent associated with that product.
  • Use in a domain name or URL.
  • Use for merchandising purposes, e.g. on t-shirts and the like.
  • Services relating to any of the above.

If you wish to have permission for any of the uses above or for any other use which is not specifically referred to in this policy, please contact us and we'll let you know as soon as possible if your proposed use is permissible. Note that due to the volume of mail we receive, it may take up to a week to process your request.

Permission may only be granted subject to certain conditions and these may include the requirement that you enter into an agreement with us to maintain the quality of the product and/or service which you intend to supply at a prescribed level. While there may be exceptions, it is very unlikely that we will approve Trademark use in the following cases:

  • Use of a Trademark in a company name.
  • Use of a Trademark in a domain name which has a commercial intent.
  • The commercial intent can range from promotion of a company or product, to collecting revenue generated by advertising.
  • The calling of any software or product by the name Varnish (or another related Trademark), unless that software or product is a substantially unmodified Varnish product.
  • Use in combination with any other marks or logos. This include use of a Trademark in a manner that creates a "combined mark," or use that integrates other wording with the Trademark in a way that the public may think of the use as a new mark (for example Club Varnish or VarnishBooks, or in a way that by use of special fonts or presentation with nearby words or images conveys an impression that the two are tied in some way).
  • Use in combination with any product or service which is presented as being Certified or Official or formally associated with us or our products or services. Use in a way which implies an endorsement where that does not exist, or which attempts to unfairly or confusingly capitalise on the goodwill or brand of the project.
  • Use of a Trademark in a manner that disparages Varnish, Varnish Software AS, Varnish Software AB or its products and is not clearly third-party parody.
  • On or in relation to a software product which constitutes a substantially modified version of a product supplied by the Varnish project, that is to say with material changes to the code, or services relating to such a product.

In a title or metatag of a web page whose sole intention or result is to influence search engine rankings or result listings, rather than for discussion, development or advocacy of the Trademarks.

Logo usage guidelines

Our logos are presented in multiple colors and it is important that their visual integrity be maintained. It is therefore preferable that the logos only be used in their standard form but if you should feel the need to alter them in any way you should keep the following guidelines in mind. It should also be borne in mind that the more you wish to vary our logos from their standard form the smaller is the chance that we will be able to approve your proposed use.

If presented in multiple colours, the logo should only use the “official” logo colours. You may use transparency and gradient/depth tools but should retain the “official” colours. A monochrome version may be acceptable in certain situations, if the use requires it (e.g. desktop backgrounds).

Any scaling must retain the original proportions of the logo.
