Capabilities
Primary structure archive. Input: a PDB ID or search query; output: experimentally determined coordinates and metadata - the source of your target structure and of nearly every training set in this list.
When to use it
The ground truth for benchmarks, templates and epitope analysis. Coverage is biased to crystallisable, well-behaved proteins and many therapeutic complexes are simply absent.

Commercial Licensing
Commercial rights — may a company use it?
Commercial use OKLicence as writtenCC0 1.0 Universal (archive data)
The RCSB usage policy page states the wwPDB policy makes PDB archive data files available under CC0 1.0, as is data from RCSB programmatic APIs. RCSB software products are separately under MIT or Apache-2.0.
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 useFree, CC0: no fee, no attribution requirement (citation is requested as courtesy). Bulk download via FTP/rsync is open.
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.
