Loop

Loop is a Russian‑origin corporate messenger designed for business teams. It provides open and private channels, threaded conversations, and voice calls with screen‑sharing capabilities. Users can access the service through desktop clients for Windows, macOS, and Linux, as well as mobile apps for Android and iOS, and a web interface.

The platform emphasizes integration, offering an open API that connects to tools such as JIRA, GitLab, GitHub, Jenkins, Zoom, Google Calendar, and many others. It supports both cloud hosting and on‑premises deployment, allowing organizations to keep data under their own control and to integrate with directory services like Active Directory, LDAP, and SSO via OIDC.

Loop targets companies that need a secure, customizable communication hub with flexible integration options. It is listed in the Russian software registry, offers a free trial period, and provides additional discounts for educational institutions, non‑profits, and startups.
