The purpose of this paper is to introduce a platform for end-user generated mobile services - so-called microservices. Design/methodology/approach: As a key component the authors present a microservice description language for user-driven mobile service creation and platform-independent service execution and rendering. The paper also gives insight into the authors' visual authoring tool. The chosen design approach is evaluated in two phases: an intermediate evaluation with a small hands-on trial and an online survey; and a final laboratory test with 24 test users in total. Findings: The paper provides empirical insights about the methods and motivations of end-users creating small mobile services. The main purposes of service creation would be mostly to exchange information, stay in contact, and just for fun (on the basis of non-commercial use). The evaluations also indicate the visual drag and drop approach of putting service blocks together as being the most favored in terms of user satisfaction. Originality/value: The concepts and findings introduced in this paper will help in designing mobile service authoring environments, which is appealing to software communities/vendors and mobile network operators. The presented platform is, to the authors' knowledge, the first designed and implemented infrastructure enabling end-user mobile service creation. %~
