PEFF UniProt Fetcher
Generate a
PEFF
file for any organism directly in your browser. Runs entirely client-side
via Pyodide
— no server involved.
Heads up: Large proteomes (e.g. human, mouse) can be
slow and memory-heavy in a browser tab — expect several minutes and
hundreds of MB of RAM. For big jobs, use the
CLI instead.

Idle. Pyodide will load on first run.
