gdal_translate, in a loop like this (using BASH on Linux, mind my
limited scripting skills but works, gifs will be stored in your
current dir):

#!/bin/bash

LIST=$(ls /the/dir/where/tiffs/are | grep -i ".tif")
#					       ^^^
#				adjust the extension as needed


for FILE in $LIST;
do

	echo
	echo Converting: $FILE

	# optional to convert all filenames to lowercase:
	# FILE_LOW=`echo $FILE | tr A-Z a-z`

	gdal_translate $FILE `basename $FILE .tif`.gif

done

opensource is not contrary to commercial - take GDAL for example :).
