The laser-driven plasma accelerator based compact undulator radiation source is currently under commissioning at ELI-Beamlines (Institute of Physics CAS, Czech Republic) in the frame of the LUIS project, which aims to deliver stable and reliable incoherent photon beam with a wavelength around 5 nm to an user-station. As the result of this project, the electron beam parameters should be improved to generate the coherent photon radiation reaching the saturation of the photon pulse energy in a single-unit dedicated undulator (LPA-based FEL). An overview of the current status of the LUIS project will be presented, including the high-power high-repetition rate laser, acceleration of the electron beam in the plasma channel, the electron and photon beam-lines with relevant diagnostics. Challenges and future development beyond the LUIS project also being discussed.
