IndexTank replace companies with Compatible API
On April 10th 2012 IndexTank will shut down their servers. I suggest to build a list of IndexTank compatible API companies.
Open Source Version: https://github.com/linkedin/indextank-engine
Searchify: http://www.searchify.com/ (Running the full open sourced IndexTank Search as a Service API)
IndexDen: http://indexden.com/ (IndexTank Compatible API - builded on top of Sphinx Search)
HoundSleuth: http://www.houndsleuth.com/ (IndexTank Compatible API)
IndexTanktoGO: http://launch.indextanktogo.com/ (IndexTank Compatible API)
Probably some more companies should be mentioned here. I've been using Searchify since early beta and it's been rock solid. All I needed to do for our indexes was change the URL and key and it just worked. If you were happy with IndexTank you should be just as happy with Searchify.
