A true revolution is underway in the field of stellar variability thanks to the growing number of ground-based and space-based facilities that are collecting time series of data over large portions of the celestial sphere. A leading role in this revolution is played by Gaia, the European Space Agency's (ESA) cornerstone mission, which has been monitoring the entire sky for over than 10 years starting in July 2014, measuring positions, parallaxes and proper motions, and collecting multi-epoch photometric data in three different passbands (Gaia G, G_BP and G_RP) of sources up a limiting magnitude G ~ 21, together with spectroscopy and spectrophotometry time series in the Ca triplet region for sources brighter than G ~ 16.5 mag. The latest major Gaia data release, Data Release 3 in 2022, published time series of multiband photometric data and parameters for approximately 10.5 million variable sources. Stellar pulsation is the mechanism driving brightness and radial velocity variations in over a third of them. I will discuss the main results and properties of pulsating stars in Gaia, with a focus on RR Lyrae stars and Cepheids, in light of their impact on the definition of the astronomical distance ladder and the study of resolved stellar populations in our Galaxy and beyond. I will present perspectives on the next Gaia release, Data Release 4, which will take place in December 2026.
