Backlog vs Flyspray

Backlog combines project management, issue tracking, and team collaboration without per-user pricing. Teams can manage issues on Kanban-style boards and use subtasks, Gantt charts, burndown charts, and issue templates, with tools varying by plan. Built-in Git repositories and Subversion support provide code management. Backlog works in a browser and on Android and iOS devices, and its open API supports custom integrations. Listed integrations include Cacoo, Slack, Jenkins, Microsoft Teams, Google Drive, Dropbox, and iCal Sync. The Free plan supports 10 users and one project; it includes 100 MB of storage, Git and Subversion, and a board. Starter costs $35 a month for up to 30 users and five projects. Standard costs $100 a month, and Premium costs $175 a month. Paid plans have a 30-day trial without a credit card, but plans cannot be changed during the trial. Enterprise adds security features such as SAML single sign-on, SCIM provisioning, audit logs, and centralized access management, and can be installed on a private server. Backlog's maker is headquartered in Fukuoka, Japan, and was founded in 2004.
