VectorBee 3.2.0 was released on April 14, 2026, including 12+ new/optimized features. Click here for details.
You may wonder how a sophisticated software like VectorBee could be free given that it takes many dedicated scientists and IT engineers to create and constantly upgrade.
It all began with our fearless leader, Professor Bruce Lahn. As the Chief Scientist of VectorBee (and also VectorBuilder), Bruce, like many of you, was a grad student who loved two things: free food at seminars and free software. But as he progressed beyond the humble grad student to positions of greater responsibilities, he realized that nothing is truly free, and someone's free food always comes out of someone else's pocket.
But Bruce also strongly believes that research software like VectorBee should be open to the entire research community, whether academia or industry. He thus pledges to finance VectorBee with VectorBuilder's R&D budget to keep it free for all.
In return, Bruce asks that you consider VectorBuilder's wonderful products and services, and also spread the good word about VectorBuilder and VectorBee. This would help us keep VectorBee free and continuously improved.
The most heartfelt thanks from us all at VectorBuilder and VectorBee!
