Gravitational instability and fragmentation in the early evolution of circumstellar disks is a common occurrence, which leads to a zoo of various effects depending on the ultimate fate of the fragments. I will demonstrate how disk fragmentation can trigger episodic accretion onto the star similar in magnitude to FU-Orionis-type eruptions, produce gas giants and brown dwarfs on wide orbits, and explain the existence of young proto-brown dwarfs in million-year-old stellar clusters.
