I will summarize some recent developments of type II and heterotic superstring field theory, following the approach of Ashoke Sen and based on the construction of the open-closed bosonic string field theory by Zwiebach. I will first recall the reasons for using SFT and then explain how the three main challenges faced by superstring field theory have been solved: inclusion of the Ramond sector, removal of spurious singularities due to the superconformal ghosts and definition of a prescription for the off-shell amplitudes.
