Capabilities
Antibody Fv structure prediction. Input: heavy and light chain sequences; output: an Fv PDB with per-residue error estimates, in under a minute - fast enough for whole design libraries, but the licence is academic-only.
When to use it
Only for academic work: fast Fv models in seconds. For any commercial antibody program use ImmuneBuilder or ABodyBuilder3 instead.

Commercial Licensing
Commercial rights — may a company use it?
Not for commercial useLicence as writtenJHU Academic Software License Agreement
LICENSE.md states only a non-exclusive, nontransferable license for non-commercial purposes; 'Commercial use of the Software requires a separately executed written license agreement.' Derivatives are bound by the same non-commercial terms.
The licence limits use to non-commercial purposes; a company needs a separate agreement.
Commercial cost — is commercial use free of charge?
No commercial option at any priceNo fee is charged, but no commercial right is granted either: the JHU Academic Software License covers non-profit academic/research institutions only. A company would have to negotiate separately with JHU; no published commercial price exists. ImmuneBuilder or ABodyBuilder3 avoid the problem entirely.
Price and rights are separate: this panel is about money, the panel above is about permission.
- Commercial OK ≠ Free of charge. A tool can be licensed for company use and still need a paid licence for a dependency (BindCraft → PyRosetta).
- Free download ≠ Commercially licensed. Weights you can download at no cost may still forbid commercial use (AlphaFold 3).
- Unverified ≠ Commercially permitted. If no published statement settles it, treat it as unknown — not as a yes.
- Every component counts. Each status considers the code licence, the model-weights terms, required dependencies and any terms of use.
Model Weights
Open weights. A separate weights licence is Not documented as its own field; where weights carry different terms from the code, that is stated in the licence explanation above.
Dependencies
Not documented as a separate field. Any dependency that affects commercial use (for example a paid PyRosetta licence) is named in the licence and cost explanations above.
