The article analyses EU law regulating the freedom to provide services in a sharing economy model, from the perspective of the rights and obligations of providers of online and underlying services. Three groups of actors are engaged in providing services in the internal market of this business model: providers of underlying services, recipients of those underlying services and online platforms (with smartphone applications) which connect providers and recipients of underlying services. Although this business model is no longer of specific interest to the EU institutions or academia, it is still present in the Member States. Therefore, it seems useful to present two aspects of the freedom to provide these services from the perspective of providers of online and underlying services: rights that providers of services derive from EU law in relations with the Member States and obligations incumbent on providers of services according to EU law.
