I'm currently doing a research on developing a web-based ontology editor.

I need to validate that the ontology edited by my tool is consistent and infer knowledge properly. Also, I would like to get some general statistics regarding the ontology.

Is there an ontology validator tool available online which I can use for this requirement?

OWL 2 Validator and OWL Metrics don't seem to be working anymore.

The OOPS! (OntOlogy Pitfall Scanner!) helps detect common pitfalls for ontology development. There is also a REST endpoint available.
