For molecular modelers using the SAMSON platform, organizing and turning the right features on or off at the right time can save both time and computational resources. Whether you’re switching between different projects, collaborating in a team, or simply exploring new functionality, knowing how to manage your SAMSON Extensions efficiently is essential.
This post walks you through how to add, try, subscribe to, and remove SAMSON Extensions using the Marketplace on SAMSON Connect. These modular building blocks serve a wide range of purposes—from visualization and modeling to simulations and AI-enhanced predictions.
Finding the Right Extension
Head over to the Marketplace section on SAMSON Connect. Here, all available SAMSON Extensions are categorized and clearly displayed. Extensions provide their own pages detailing what they do, who authored them, their platform compatibility, and the SAMSON versions they support.

Adding Free Extensions
For extensions available freely (i.e., not requiring a subscription), you can simply hit the Add button once signed in. You’ll see it change to Added.


Restart SAMSON afterward, and it will automatically fetch and install your selected extension.
Trying or Subscribing to Paid Extensions
Some extensions require a subscription. You have two options:
- Try an extension for free via the Request trial button—no credit card required.
- Subscribe monthly or yearly. If you’re affiliated with a university, consider selecting the academic plan.




Removing an Extension
To remove an extension, visit either your Marketplace or go through the Account > Settings menu and click View my extensions. Hover over the Added button on the extension you wish to remove—it will change to Remove. Click it to proceed. After restarting SAMSON, the extension is uninstalled.

Managing Subscriptions
If you are subscribed to paid extensions, navigate to Account > Settings > View my subscriptions to adjust or cancel them.


Keeping Track of Removed Extensions
Even after removal, extensions stay visible in your account under View my extensions so you can easily reinstall them later if needed. When experimenting with multiple extensions or optimizing the working environment, this flexibility is particularly helpful.
In summary, SAMSON Connect provides an intuitive interface for managing your molecular modeling toolbox. Whether you are trying a new quantum chemistry module, removing an old one, or fine-tuning your environment for a specific workflow, everything you need is just a few clicks away.
