The whole stackvs. half a stack.
Productboard is feedback-led. Canny is voting-led. Featurebase is changelog-led. Productstack is the only one that runs the whole loop: strategy → plan → ship → learn, with AI in every layer.
Feature by feature.
Honest comparison. We list partial coverage as "partial", not as a green checkmark.

Productstack vs.Productboard
The category-defining product OS, built before AI was the wedge.
Productstack is what Productboard would look like if it were rebuilt today.
AI in every layer, not bolted on.
Productboard added AI features in 2024. Productstack was designed from day one with AI in the loop, OKR drafting, idea dedupe, card suggestion, release authoring, KB inline rewrite. Every layer.
Built-in changelog + KB.
Productboard's changelog is a recent paid add-on; there's no first-party KB. Productstack ships both as core surfaces, with AI authoring tying them to released work.
Pricing that respects you.
Productboard quotes start at $59/mo and scale fast. Productstack starts at $39/mo with the full stack included, no tier games on the layers themselves.
Productstack vs.Canny
A great public ideas board, and not much else.
Canny does Ideas well. Productstack does Ideas, plus the rest of the product loop.
Full product OS, not just Ideas.
Canny is built around the public ideas board. Productstack covers OKRs, roadmap, releases, KB, and feedback, all wired together. If you want one tool not five, the choice is obvious.
AI features Canny doesn't have.
AI release drafting, KB authoring, OKR + card + idea suggestion, feedback categorisation. None of those exist in Canny.
Embed widget that's actually useful.
Productstack's embed shows the unread changelog badge on your customers' screens, surfaces feedback via three launcher styles, and ties signal to identity. Canny's embed is the ideas board in an iframe.
Productstack vs.Featurebase
The cheap challenger, strong on price, light on strategy.
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.
One tool. The whole loop.
Migrate from any of them. Free for 14 days. We'll help you import your ideas + roadmap on day one.
