Bulk discount codes, PPP regional pricing, price changes, customer CSV export and AI listing SEO — a Chrome extension that uses your own Gumroad API token. No server, no middleman.
You paste your own Gumroad API token (created in Gumroad → Settings → Advanced → Applications). It is stored only in your browser, and GumKit talks directly to the official Gumroad API — there is no GumKit backend. Bulk jobs run as a paced, pausable queue that respects Gumroad's rate limits.
