We present optical observations and analysis of a bright type Iax SN~2020udyhosted by NGC 0812. The light curve evolution of SN~2020udy is similar to otherbright Iax SNe. Analytical modeling of the quasi bolometric light curves of SN2020udy suggests that 0.08$\pm$0.01 M$_{\odot}$ of $^{56}$Ni would have beensynthesized during the explosion. Spectral features of SN 2020udy are similarto the bright members of type Iax class showing weak Si {\sc II} line. Thelate-time spectral sequence is mostly dominated by Iron Group Elements (IGEs)with broad emission lines. Abundance tomography modeling of the spectral timeseries of SN~2020udy using TARDIS indicates stratification in the outer ejecta,however, to confirm this, spectral modeling at a very early phase is required.After maximum light, uniform mixing of chemical elements is sufficient toexplain the spectral evolution. Unlike the case of normal type Ia SNe, thephotospheric approximation remains robust until +100 days, requiring anadditional continuum source. Overall, the observational features of SN 2020udyare consistent with the deflagration of a Carbon-Oxygen white dwarf.
