DeepView is described as 'RFeye DeepView software is the ultimate signal extraction tool. Its robust indexing feature allows users to sift through multi-terabyte datasets and quickly find and export signals of interest (SOIs)'. There are three alternatives to DeepView for Mac, Windows, Linux and Online / Web-based. The best alternative is WaveTower. It's not free, so if you're looking for a free alternative, you could try HackRF.
WaveTower® (formerly Vantage) is a patented platform from RF Venue that allows you to remotely monitor and manage RF spectrum activity over the web and on your Mac desktop. Monitor and manage local RF conditions from across town or across the globe.
