Open-source Vinted alternatives

Mercur is an open-source, headless platform for building multi-vendor marketplaces and is presented as an alternative to Mirakl. It adds vendor onboarding, multi-vendor catalogs, offers, commissions, and automated payouts on top of a commerce core. The topics point to Medusa as that core. It is written in TypeScript and released under the MIT license.

The platform supports B2C, B2B, and hybrid marketplaces and includes a storefront, a vendor panel, an admin console, and integrations. The README stresses ownership: you self-host on your own infrastructure with full source access, and there is no percentage of gross merchandise value, no per-transaction fee, and no vendor lock-in.

Documentation, a live demo, and a Discord community are available. Mercur suits teams launching a marketplace who want to avoid both a revenue-sharing SaaS platform and a from-scratch build, and who have the engineering capacity to operate and customize the system.

GrandNode is an open-source e-commerce platform built with ASP.NET Core and MongoDB. Its use of a NoSQL database is the main design choice, aimed at fast page rendering and the ability to handle traffic spikes, and it targets businesses that want a customizable shop with room to grow.

The platform supports several business models, including B2B, B2C, multi-store, multi-vendor, multi-tenant, multi-language and multi-currency setups, so one installation can run several storefronts. It is designed to integrate with existing third-party software, and the project provides themes, plugins and integrations, a forum and a demo store. Premium support is offered separately by the maintainers.

GrandNode is written in C# on .NET and released under the GPL-3.0 licence. You can install it from the documented steps, build from source or run it locally, and host it on your own servers. It suits development teams and merchants in the .NET ecosystem who prefer MongoDB over a relational database for their store.

Shuup is an e-commerce platform built in Python on the Django framework, aimed at businesses that need either a conventional single-vendor online store or a multivendor marketplace where several sellers operate on the same storefront. It is positioned as a flexible, customizable foundation rather than a fixed, one-size-fits-all storefront.

Being built on Django, it benefits from Django's mature ecosystem for authentication, admin tooling and database management, and its topics indicate dedicated support for multivendor commerce scenarios, where a single platform instance can host multiple independent sellers. Further feature specifics were not available from the project's homepage at the time of this summary, so refer to the GitHub repository and documentation for details.

Shuup is written in Python with Django and the repository metadata lists its license as Other, so check the license file before relying on it for a commercial deployment. As a self-hosted Django application, it is deployed on infrastructure the operator controls.
