Bonjour,

I am wondering why the freeserif fonts work perfectly with devanagari
script with xelatex but lualatex is unable to make correct correct
ligatures.

Fonts Sanskrit2003 is ok with both fonts.

Run xelatex and luatex on this MWE:

<--------------------------------------------------------
\documentclass{article}

\usepackage{fontspec}

\newfontfamily{\sanskritdev}[%
Language=Sanskrit,%
Script=Devanagari,%
]{%
Sanskrit2003}

\newfontfamily{\freeserifdev}[%
Language=Sanskrit,%
Script=Devanagari,%
]{%
FreeSerif}

\begin{document}

{\sanskritdev अथा छन्दःशास्त्रम् पिङ्गलः हलायुधः}

{\freeserifdev अथा छन्दःशास्त्रम् पिङ्गलः हलायुधः}

\end{document}
---------------------------------------------------------------->

xelatex always uses the harfbuzz renderer (which is better for such
scripts) but lualatex only if you request it:

\newfontfamily{\freeserifdev}[%
Renderer=HarfBuzz, %switch to harfbuzz
Language=Sanskrit,%
Script=Devanagari,%
]{%
FreeSerif}
