Available online on https://atomgraph.github.io/SPARQL-Playground/
Unlike other server-based SPARQL playgrounds, this runs completely in the browser. It only accepts RDF data from user input and does not query remote datasources.
Multiple RDF input/output formats as well SPARQL result formats are supported.
Inspired by martin-honnen's Saxon-JS 2.5 XSLT 3 Fiddle.
