Clients of Triple Pattern Fragments (TPF) interfaces demonstrate how a SPARQL query engine can run within a browser and re-balance the load from the server to the clients. Imagine connecting these browsers using a browser-to-browser connection, sharing bandwidth and CPU. This builds a fog of browsers where end-user devices collaborate to process SPARQL queries over TPF servers. In this demo, we present Ladda: a framework for query execution in a fog of browsers. Thanks to client-side inter-query parallelism, Ladda reduces the makespan of the workload and improves the overall throughput of the system.
