Description

Stallora is a working multi-vendor marketplace, and a production-shaped Spring Boot microservices reference implementation. Several independent shops sell through one storefront; a basket can hold items from all of them; at checkout the order splits into one delivery per shop; each shop fulfills its own slice and is settled separately with commission taken. You get the whole thing — six services, a server-rendered storefront, two web consoles and a Flutter app for iOS and Android — as source.

Before you buy: this is six JVMs, Kafka and PostgreSQL. It requires a VPS with at least 6 GB of RAM (8 GB recommended) and Docker. Measured peak on a cold start is 3.35 GB across all thirteen containers. It will not run on shared hosting or cPanel, which cannot run Docker or a JVM at all. Payments are deliberately mocked — one interface to implement, documented step by step.
