Trademark: Conn3x

Last updated 27 October 2026

Conn3x is open source under the Mozilla Public License 2.0. That licence covers the code. It doesn't cover the name or the logo, which tell people where a piece of software comes from. This page explains how to use them. It follows the same approach as the Linux Foundation's trademark policy, which OpenTofu and many other projects use.

The marks

"Conn3x" and the Conn3x logo and mark are trademarks of James Conway, held for the project. As the governance document sets out, the plan is to move them to a neutral foundation once Conn3x has maintainers from more than one organization.

Fine without asking

Saying what's true: that your project, product or service works with, supports, is built for or is compatible with Conn3x.
Naming a shared circuit after what it does, such as circuit-nginx, and saying it's a circuit for Conn3x.
Writing, teaching or speaking about Conn3x: blog posts, videos, courses, books and talks.
Using the unmodified logo to link to conn3x.org or the repository, or to show that something works with Conn3x.
Running community groups and meetups about Conn3x, as long as the name shows they're community-run.
Distributing unmodified Conn3x releases, or packages built from an unmodified release, under the name Conn3x.

Ask first

Using "Conn3x" in the name of a product, company, service, domain or social account.
Anything that suggests the project endorses, sponsors or certifies you when it doesn't.
Selling merchandise with the name or logo.
Using a modified, recoloured or combined version of the logo.

Forks and modified versions

You're welcome to fork Conn3x and ship your own version; the licence allows it. If you distribute a version with changes, give it a different name and logo, so nobody mistakes it for the original. Saying it's "based on Conn3x" or "a fork of Conn3x" is fine.

Using the name and logo well

Write it as Conn3x, with a capital C and a 3, or conn3x for the command.
Keep the logo's colours, proportions and the space around it. Don't add effects or put it inside another logo.
Use the version made for your background: light marks on dark, navy on light.

Logo files

The orange is #ff7a2e on dark and #e85d0c on light. The type is Schibsted Grotesk.

Questions and permission

Not sure if your use is fine? Ask at legal@conn3x.org, and tell us what you have in mind. We'd rather say yes than see Conn3x go unmentioned.
