The JSON-LD Playground web app is very useful for validating or exploring #ActivityPub data. However, if you prefer the command line or want to integrate Playground-like functionality into scripts, the ld-cli program could be useful. It’s definitely been useful for me. Features include: expand, compress, flatten, frame and conversion to/from RDF (N-Quads).
