BatchGEO is described as 'Make maps from a list of multiple addresses, create a mobile optimized map or locator. Free hosting for your custom interactive map or locator' and is an website. There are more than 10 alternatives to BatchGEO, not only websites but also apps for a variety of platforms, including Mac, Windows, iPhone and iPad apps. The best BatchGEO alternative is Plenum Atlas. It's not free, so if you're looking for a free alternative, you could try Mapline or ZeeMaps. Other great sites and apps similar to BatchGEO are Badger Maps, Mapme, Sharemap and Map my customers.
Table & Map has a lot of features that BatchGeo makes you pay for. They also have less strict free usage so you can get a lot of value without paying. I use the paid tier because I have a lot of data, but you can get away with the free tier if you are trying to map only a few markers.
