FAQ
- Are these “official” vendor pairings?
- No—alternatives are category peers for discovery, not paid placements. Vendors can still claim profiles and respond to reviews on their product pages.
- Why is my favorite tool missing?
- Only ACTIVE listings in the same primary category appear. Multi-category products may move when their primary category is updated.
