Productstack vs.Featurebase
Featurebase nails ideas + changelog at a friendly price. Productstack adds the strategy + AI layer that turns it from a tool into a product OS.
OKRs + AI strategy drafting.
Featurebase has no OKR layer and no AI suggestion features. Productstack ties every roadmap card and shipped release back to the goal it serves, and drafts those goals from your context.
AI authoring across the surface.
Release drafting, KB writing, inline rewrite, feedback categorisation, idea dedupe, Productstack runs Claude across the whole loop. Featurebase has lightweight AI dedupe at most.
Same simple pricing.
Productstack starts at $39/mo with the full stack. You're not paying much more for substantially more product.
