Many e-commerce shops want to become marketplaces, but they lack a Seller Center. A Seller Center is important because it lets sellers manage products, prices, stock, and orders. Commercial solutions like Mirakl or Marketplacer exist, but they are expensive. Surprisingly, there is no good open-source alternative available. This is strange because many marketplaces must have built their own Seller Centers already.
To solve this, I started developing an open-source Seller Center (OSSC). It will help shop owners to expand their shops into marketplaces. The goal is to make a simple and reusable solution that others can use without big costs.
I try to keep everything simple and efficient. For this, I follow three main rules during development:
- Don’t over-engineer: Build only what is needed and avoid unnecessary complexity (I am building a PHP app, nothing fancy)
- Reuse existing tools: Use frameworks and libraries that already solve common problems (FilamentPHP in my case)
- Use AI when helpful; especially for coding (Windsurf is my prefered IDE).
I have worked on this project for a few days and completed about 25% of the minimum functionality. There are two user roles with basic features: Marketplace Owners and Sellers.
