In this contribution we review the recent advances in star and planet formation studies
that have been allowed by long baseline optical interferometers in the last few years.
We see how interferometry continues to bring significant observational constraints
on complex processes such as accretion/ejection, dust sublimation and evolution and
planet formation. We discuss the implication of the arrival on sky of GRAVITY and
MATISSE at VLTI together with MYSTIC and MIRCX at CHARA and how these new facilities
can contribute answering to the burning questions of planet formation.
