Aha! vs Skadi: What are the differences?
What is Aha!? Roadmapping software for PMs who want their mojo back. Set product strategy, visualize and share roadmaps, and articulate features so your product development teams can build what matters.
What is Skadi? 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.
Aha! and Skadi can be primarily classified as "Project Management" tools.
