Asteroseismology of solar-like oscillators has undergone a remarkable transformation over the past decade, propelled by high-precision photometric data from Kepler, K2, and TESS, alongside significant advances in stellar modeling. These developments have enabled detailed investigations of stellar interiors across a broad range of evolutionary stages - from the main sequence, through the subgiant phase, to the red giant branch. In this talk, I will present the fundamental methods of asteroseismology applied to solar-like oscillators and highlight recent breakthroughs based on both global seismic parameters and individual oscillation mode frequencies. I will emphasize how these tools have deepened our understanding of stellar structure, evolution, and internal dynamics, particularly in evolved stars. Key results include constraints on internal dynamics, mixing processes, and stellar binarity. I will also discuss insights gained from ensemble asteroseismology across diverse Galactic populations. Ongoing challenges will be addressed, such as the calibration and limitations of scaling relations, the phenomenon of mode suppression, and the integration of seismic diagnostics with spectroscopic and astrometric data. Finally, I will outline how upcoming missions and surveys, in particular ESA's PLATO that are expected to shape the next era of solar-like asteroseismology.
