Capabilities

Reference sequences and annotation. Input: accession, gene or text query; output: canonical sequences, isoforms, domains, PTMs and functional annotation - the identity layer for any target you design against.

When to use it

Canonical source for target sequences, isoforms, domains and PTM annotation before any design run. Annotation quality varies sharply between reviewed (Swiss-Prot) and unreviewed (TrEMBL) entries.

Commercial Licensing

Commercial rights — may a company use it?

Commercial use OK

Licence as writtenCreative Commons Attribution 4.0 International (CC BY 4.0)

The licence read at the source allows use by a company. Attribution or copyleft conditions may still apply — read the note.

Commercial cost — is commercial use free of charge?

Free for commercial use

Free under CC BY 4.0, bulk downloads included.

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.
