RCSB Protein Data Bank versus AlphaFold Protein Structure Database
Compare	RCSB Protein Data Bank	AlphaFold Protein Structure Database
Verdict	Depends	Worth it
Best for	Structural biology researchers	Structural biologists
Who it's not for	Businesses shopping for software . nothing to buy	Labs needing experimentally verified structures (use the PDB)
Privacy	No known public vulnerabilities found in the sources reviewed.^⁴	No known public vulnerabilities found in the sources reviewed.¹⁴
Support quality	No support model in evidence	EBI training courses exist; no dedicated support
Public sentiment	Reddit chatter about 'RCSB' is almost entirely an unrelated truck community, while scientific users treat as the standard protein structure reference.^⁷	Academic reviews report broad scientific impact, while Reddit users debate its value for protein design tasks.¹⁰
Biggest gotcha	No SLAs or commercial support . it is a public resource, not a vendor	Check per-residue confidence scores before trusting any model in lab work.¹⁰

Pick RCSB Protein Data Bank when

Structural biology researchers
Bioinformatics developers needing structure APIs
Science educators and students
Drug-discovery teams

When RCSB Protein Data Bank is not a fit

Businesses shopping for software . nothing to buy
Non-scientists wanting a general-purpose database
Teams needing vendor support or SLAs
Buyers who arrived via 'RCSB' truck-forum links . unrelated

Pick AlphaFold Protein Structure Database when

Structural biologists
Bioinformaticians and computational biologists
Drug discovery researchers
Protein science students

When AlphaFold Protein Structure Database is not a fit

Labs needing experimentally verified structures (use the PDB)
Guess: teams designing novel proteins or studying complexes
Non-scientists expecting a plug-and-play AI app
Buyers shopping for software; this is free public data
