ProductPlan vs Skadi: What are the differences?
Developers describe ProductPlan as "Visual product roadmap and IT roadmap software". Communicate your strategy with cloud-based roadmap software. Easily visualize, prioritize, and share your company’s product and dev roadmap. Integrates with JIRA, Pivotal Tracker, Team Services, and Slack. On the other hand, Skadi is detailed as "Self-hosted Trello alternative with a 10 second installation". Skadi doesn't need installation or administration. It's a single static binary file. You don't even need to set up a webserver or a database. Linux and OS X are supported. Windows support is coming soon.
ProductPlan and Skadi can be primarily classified as "Project Management" tools.
