We describe the latest results to develop brilliant incoherent and coherent radiation sources based on laser-plasma wakefield accelerators. We demonstrate both experimentally and theoretically a brilliant gamma ray sub 10 femtosecond source based on betatron radiation in the plasma density wake trailing behind an intense laser pulse. Furthermore, experimental and theoretical progress towards a compact free-electron laser based on a laser-plasma wakefield accelerator will be discussed.
