I've been looking for Roadmap software for my day job. It's an oddly challenging task. I had this whole rigmarole last year too and we settled on a product called "TeamWeek". They have since re-branded to Toggle Plan.
They were alright but a lot of my staff found it cumbersome and overly complicated. We also tried Monday.com, Aha and various other such platforms but the problem there is that they are full blown project management suites. We use Jira for that and JUST need a roadmap, and a simple one at that.
So I'm going to have a go at it myself. Just simple, chronological roadmap software for individuals or teams. Private or public facing.
Here's what I'm thinking so far
