I’m going to let you in on a little spoiler right away with this one. There’s no such thing as product roadmap software in and of itself. There are a few reasons for this, and I completely understand them logically, myself.
The primary reason is that this roadmap concept isn’t even much of a thing so much as it’s a buzzword. It’s just an umbrella term for the development cycle or journey of a product either overall, or through the production, distribution and use phases.
Lots of concepts like this exist, visualizing these sorts of cycles, processes and so on. But it’s really nothing, and all the chatter about it online lately is much ado about nothing, if you’ll pardon the pun.
So, I can’t give you a list of product roadmap software, for the same reason I can’t give you Santa Clause.
Well, I’ll try to recommend a few programs that solve the same problems, more or less, and may be useful to you?
This is probably the closest direct analog I could come up with, and it’s a general roadmapping tool. So, it could be used for the product roadmap, if you can actually come to a logical decision about what actually constitutes a proper roadmap for this in the first place, which, well, good luck.
It supports interactive Gantt charts, grid views, and a bunch of other really fun stuff. So, it might do.
This one’s designed as a product concept tour creator, and as a result, is very useful for just that. And, this is something you’ll find useful to present and represent your ideas as you develop them and as you present them to stakeholders as well.
It’s interactive, themeable, cheap and free of any engineering responsibilities on you. Honestly, I think this is probably the best suggestion for you out of all of these, in a direct substitution for the nonexistent thing you seek. So, look at this one first, actually. It’ll probably prove quite useful.
This is also known as “Product Configurator”, and is basically a visual tool for prototyping products and laying out logistics on them for projection tests and so forth. This one’s a little more abstract for this list, and I openly admit I’m really reaching.
But despite that, this is actually something you will need before it’s all said and done, so I am comfortable with recommending you take a look at it.
In truth, there probably never will be software exactly like what you were looking for, and a big part of that is poor definitions for the actual standard rules for how product roadmaps should work and the like.
It’s just not something that, for now, lends to the creation of a niche for something not that widely used and not that clearly defined all in all.
So, there’s no product roadmap software, and there probably won’t be. These are the best things I can suggest for now, so take them for what they’re worth, I suppose.
