Stop retyping measurements into eBay at midnight. Mainframe wires photo uploads, comps, shipping, and buyer DMs into one gateway that turns sourcing runs into live listings.
Start free →No lister assistant. No folder of photos. Just outcomes a one-person reseller needs.
When you drop a photo into a folder → Mainframe identifies the brand with OpenAI vision, pulls 90-day comps, and generates an SEO-optimized draft ready to publish.
When a buyer sends "best offer" → Mainframe checks your floor price, accepts or counters in your voice, and auto-creates the shipping label the moment it's paid.
When a listing passes 60 days without a watcher → Mainframe refreshes title, re-shoots the hero photo with a new background, and drops it in a weekend Markdown Madness batch.
Every vendor a reseller already knows — one gateway, zero plumbing.
Tell Mainframe about your niche. We wire the rest.
