SketchUp is the world’s most loved 3D modeling software. And for good reasons.
As a platform for professionals, however, SketchUp is surprisingly underrated, and still mistaken for a hobby tool. We are here to change that.
By plugging in the power of extensions, SketchUp has opportunities to reach more professional levels of use, to extend into new industries, and to grow globally.
We want to drive this growth. We are the Extensioneers Guild.
The Guild is an independent association of professional software developers. The Guild’s accredited members invent, program, and deliver user-friendly extensions that supercharge what industry professionals can do with SketchUp.
We empower users. Our public plugins and custom development services have helped thousands of companies specialize SketchUp, streamline workflows, and achieve demanding business goals.
We turn visions into reality. Every day, architects, designers, and engineers are using our extensions to quickly translate new ideas into understandable 3D models.
We build trust. Together with millions of users, the Extensioneers Guild helps make SketchUp the world’s leading platform for professional 3D concepting, design, and visualization.
You came for the fun. Now stay for the power.

The Guild welcomes new members.
To become an accredited Guild member, you will need to:
The applicant should demonstrate having developed – or having significantly contributed to a team that has developed – one or more SketchUp extensions to high professional standards. Such extensions may be big or small, public or private, open-source or proprietary.
Alternatively, the guild may also accept non-developers, provided that the applicant can demonstrate having in other ways made significant contributions to the SketchUp extension developer community.
The Extensioneers guild is a know-your-members community. After inquiry, the applicant will receive a form to submit full contact details, name of any associated company or organisation, and references to SketchUp extensions completed.
The code of conduct outlines the guild's expectations for its members. This includes upholding high professional standards and a constructive dialog on shared business challenges.
The guild reviews each application individually. The guild welcomes new applications. To get in touch, simply use this website's contact form.
The fee currently is 100 Euro per individual member per calendar year. The guild's finances are managed transparently via Open Collective.
