Abstract The design and implementation of collective actions in model protocell communities is an on‐going challenge synthetic protobiology. Herein, we covalently graft alginate or chitosan onto the outer surface semipermeable enzyme‐containing silica colloidosomes to produce hairy catalytic protocells with pH‐switchable membrane charge. Binary populations enzymatically active exhibit self‐initiated stimulus‐responsive changes spatial organization such that mixed community undergoes alternative modes electrostatically induced self‐sorting reversible co‐clustering.
