We build GrowSocialelion, so read every table here knowing that. Channel support and plan prices were compiled from public listings and vendor pages on 2026-08-27; a tool's own site always wins over this page. GrowSocialelion's own column is generated from its live platform catalog, so it cannot claim a network the app does not publish to.
