See the supporting checkStack logic
One role per tool, one reason to remove it
A durable stack begins with recurring decisions: discover, validate, produce, monitor, and account for cost. The final recommendation will assign a tool only where it removes enough work to justify its full annual cost.
If two products solve the same job, the stack must show why both remain. Otherwise the default is to remove the overlap.
Checked inputs
Prices, plan limits, and evidence-backed roles
Book Bolt, Publisher Rocket, eRank use price and plan-limit details checked on 2026-07-14. Where a dated workflow session or the 50-keyword comparison exists, the role card links to it; otherwise it stays limited to the documented plan scope.
These inputs can explain cost and available limits. They do not establish which tool improves results for this seller segment.
True-Cost model
Annual cost changes when the seller changes
The embedded calculator is pre-set to this segment but never assumes a standard seller. Listing volume, platforms, billing preference, and overlapping features remain adjustable.
Cost outputs use prices checked on 2026-07-14; product-performance and value conclusions need segment-specific workflow outcomes before they can be published.
Tool finder
If the stack feels generic, narrow the question
The five-question finder converts platform, product type, revenue stage, budget, and bottleneck into a transparent rule-based recommendation. It explains why an item appears and what evidence is still missing.
Results are not individually indexed and canonicalize to the finder route.
