Pricing page

The dollar amount is not a score. Rankings do not read it.

API flag: seed says yes. MCP flag: not marked. These flags are notes, not an audit.

Outbound link

No public affiliate program was recorded for this tool in the Oct 14, 2026 research, or it was not checked. Absence of a program does not change any score.

We may earn a commission if a tracking link is connected and you buy through it. It never changes ranks. In this v1 seed, tracking URLs are empty, so “Open site” goes to the vendor. Sponsorship rules.
