Emerald Markets is a second-hand marketplace built on open-source software — browse the stalls online, or find us in person. Bid on a lot, or buy it now.
Listings refresh as sellers add new stock
Emerald Markets runs on open-source marketplace software from the ground up — the code behind listings, bidding, and payments is public and auditable, not a black box.
Your listings and account data aren't tied to a closed platform — the underlying software can be self-hosted by anyone.
Fixes and features come from a real, visible codebase — not a support ticket disappearing into a queue.
The same open-source system runs our point-of-sale on the stall floor and the listings online — one record, not two.
List it in a few minutes — set a starting bid, or a fixed price, and choose collection or post.
