Nil is a pure zero footprint viewer with nothing to install and no restrictions on browser use. Many competing products claim to be zero footprint, but require plugins, specific browser or lack tablet or mobile device support. These limitations diminish the true value of a zero footprint, which decrease cost of ownership by enabling deployment anywhere with minimal IT support. Many other zero footprint viewers also have extremely basic functionality and severely compromised performance. By contrast, Nil delivers a fully interactive experience, with functionalities comparable to a dedicated standalone diagnostic workstation, all on a pure zero-footprint platform.
