CheckUser displays a cookie consent banner and cross-sells eSIM data via a partner site (zamesims.com). The username checker itself is free with no signup. Trademark reports are paid (£3.99 per search). NameSniper has no display ads or third-party cross-sells.
No public API or developer documentation surfaced on checkuser.org. NameSniper has a v1 REST API and a remote MCP server for AI agents on Pro ($9.99/mo) and Business plans.
No. CheckUser offers checking only - no AI naming. NameSniper generates names with AI and scores each by Ownability - how available the name is across domains, the major social handles, and trademarks.
