PyPI vs. Simple Index

Question

I saw the mention of both index and simple index in relation to PyPI, an example is given in the devpi documentation . Is there a difference between the two indexes? Are they the same or do they have different access control functions or functions, for example?

Answer 1

The "simple" index protocol is read-only, intended for automatic use, and is defined in PEP 503 . Other protocols with greater functionality can be defined by specific repository servers, but they can probably only be used with these own server tools.
