It all depends what "works" mean for you. For sure
-allow_projection_difference will result in *something*, but that will
be pure garbage. It will completely ignore the CRS information. The
-allow_projection_difference flag is meant for tiles that are
fundamentally in the CRS but coming from different formats/providers
where the CRS don't exactly compare to equal due to mundane
differences. If you want on-the-fly reprojection, you should rather use
"gdal driver git create" to create a GTI compatible index, since the GTI
driver can perform on-the-fly reprojection.

That's kinda why I was asking. This works:
gdalbuildvrt -allow_projection_difference \
result.vrt \
STACIT:"/vsis3/sentinel-s2-l2a-stac/2025/12/18/S2C_OPER_MSI_L2A_TL_2CPS_20251218T212314_A006718_T11SMA.json":asset=scl
\
STACIT:"/vsis3/sentinel-s2-l2a-stac/2025/12/17/S2B_OPER_MSI_L2A_TL_2BPS_20251217T200148_A045870_T10JBQ.json":asset=scl
This does not:
gdal raster stack \
STACIT:"/vsis3/sentinel-s2-l2a-stac/2025/12/18/S2C_OPER_MSI_L2A_TL_2CPS_20251218T212314_A006718_T11SMA.json":asset=scl
\
STACIT:"/vsis3/sentinel-s2-l2a-stac/2025/12/17/S2B_OPER_MSI_L2A_TL_2BPS_20251217T200148_A045870_T10JBQ.json":asset=scl
\
result.vrt --overwrite
Is there a way to create .vrt with different projections in GDAL cli,
like gdalbuildvrt does?
Thanks!

Hey Even,
Will do.
In this case I was working with Sentinel L2A. One raster was zone 10
and the other was zone 11, which would cause stack to complain.
huh, and what result do you expect from stacking tiles in different
UTM zones, when no on-the-fly reprojection is done ... That will
result in non sense.
