SonarLint can connect to either SonarQube or SonarCloud to enable communication of issue reporting and other team decisions between team members. This connection is known as connected mode, and it can be easily set up from within your preferred IDE.
While in connected mode, SonarLint receives notifications from SonarQube/SonarCloud about your Quality Gate changes and new issues. Smart notifications can be enabled and team decisions can be shared. It also helps developers ensure their new code is clean by offering the option to restrict the focus of detection to issues in New Code according to the definition configured in SonarQube/SonarCloud.
Connected mode also unlocks access to various coding languages (the list of languages varies by IDE).
In connected mode advanced issues detected in the branch analysis are reported in the IDE, such as taint vulnerabilities and data flow bugs.
