trackem2 should always be mentioned here. I think it only does translation
and some warping (see site, haven't tried it yet).
then there is xuvtools but it was buggy when I tried it. they claim it to be
better than Imaris at least.

it's not obvious to me what you expect the output to look like. you want a
volume out of this or just aligned images? microsoft research has their
massive photo assembler which is the closest I recall to just aligning
images in 3d.
for volumes, well, there is the work on assembling SPIM images (rotated, a
little translated) for zebra fish but this assumes you have quite a number
of images. their algorithm requires that beads are placed a bit everywhere
to find the position.
