One of our missions is to offer Noodle to companies of all sizes and markets. By keeping the price affordable we are able to do that. The 30 Day Trial is a free version of Noodle for up to 15 employees to evaluate the product. Cloud Pro is a paid monthly subscription and includes 10GB of storage space. On Premise is a one-time payment and for companies that want to use Noodle behind their firewall or sync with Active Directory.
