Gemini vs MantisBT

Teams can manage test plans and produce road maps, change logs, and Scrum burndown charts. Gemini connects with tools including Visual Studio, Outlook, Slack, GitHub, Bitbucket, Team Foundation Server, Subversion, Git, and Mercurial. It also offers a REST API, webhooks, an apps framework, and the Breeze app for turning inbound email into tickets. Gemini runs on the web, Windows, API, and self-hosted deployments. Cloud costs $10 a month per user, billed monthly, and includes unlimited projects and content and product support. Self-host costs 850.00 USD once for 10 users. Cloud hosting supports Forms authentication, but not Windows Authentication or Active Directory. Self-hosted Gemini 7.6.0 and later requires Windows Server 2019 or later, SQL Server 2019 or later, and TLS 1.2 or later.
