Gadu-Gadu uses its own proprietary protocol. As with IQC, users are identified by unique serial numbers. Protocol's features include status messanges, file sharing , and VOIP. Users may format and embed images in messages. Since client version 6.0, an experimental secure connection mode can be used.

The official client provides over 150 emoticons, allows grouping contacts, sending SMSand integrates with other services ran by the same company: a virtual Internet dial-up, a socisl networking site MojaGeneracja.pl and an internet radio Open.fm. Because of this, many users consider newer versions bloatware, so the older versions are still common.

Many unofficial plugins have been created to expand its capabilities.
