  We show that there are certain perturbatively stable non-supersymmetric $AdS$
vacua which are also brane-jet stable. Also we extend the analysis of
brane-jets to the $AdS$ vacua from curved domain walls like Janus solutions.
First, we apply the brane-jet analysis to the non-supersymmetric Janus
solutions of type IIB supergravity found by Bak, Gutperle and Hirano. Second,
we study the brane-jet of $AdS_4$ vacua from eleven-dimensional supergravity on
Sasaki-Einstein manifolds: the supersymmetric and the skew-whiffed
Freund-Rubin, the Pope-Warner, and the Englert solutions. Third, we examine the
non-supersymmetric $AdS_4$ vacua from $Q^{1,1,1} $ and $M^{1,1,1}$ manifolds
discovered by Cassani, Koerber and Varela. It turns out that all the $AdS$
vacua we consider in this work are brane-jet stable. Especially, the Janus, the
skew-whipped Freund-Rubin, and the $AdS_4$ vacua from $Q^{1,1,1} $ and
$M^{1,1,1}$ are perturbatively stable within known subsectors of truncations
and also brane-jet stable.
