Jira Client Lite is a free complex desktop client for Atlassian JIRA. Free for small teams using JIRA starter (10-user) license. Free for open-source projects.

You can work with issues when theres no connection to JIRA. JIRA Client stores all downloaded issues and metadata in local database, which allows you to browse issues, make changes and create new issues. JIRA Client will synchronize with the server later.
