Vatsaraja was a significant Sanskrit dramatist. This eminent Sanskrit theatre personality composed several plays to exemplify the conventional classical rupakas or forms. He wrote that he served Paramardi Deva i.e. the king of Kalinjara, as minister. His Tripuradaha i.e. 'Burning of the Three Cities' is a dima, Rukminiharanme i.e. 'Rukmini's Abduction is an in four acts, and Samudramanthana i.e. 'Churning of the Ocean' are rare extant texts for each of these types.

Vatsarajs's three one-act scripts also survive. These can be mentioned as Kiratarjuniya i.e. 'Arjuna and the Kirata' or a vyayoga, Karpuracarita i.e. 'Karpura's Exploits' or a bhana and Hasyacudamani i.e. 'Crest Jewel of Laughter' or a prahasana. All were staged at court, and were above the pedantry and wordy vocabulary characteristic of decadent Sanskrit theatre during this period.
