Sonar by Sellics (no longer available): what happened and alternatives
Sonar by Sellics was a free Amazon keyword research tool by Sellics (now Perpetua). It is no longer available; this page records what it did and the closest live alternatives.
Status, checked 13 October 2026: no longer available
sonar-tool.com, the address of the free Sonar keyword tool, no longer resolves to a website, and sellics.com now redirects to Perpetua, whose site carries a page titled "Sellics joins forces with Perpetua". We found no live version of Sonar. The review below is kept for reference only. Perpetua has since said so itself: its Sonar page, still titled "Sonar: Amazon Keyword Research Tool," now opens with "We're sorry, but this feature is no longer available."
Closest live alternatives we review: Helium 10, Jungle Scout.
All tools whose status changed: Amazon seller tools that shut down, merged or changed owner.
BagEngine score when last reviewed: 6.5/10
