tner and NeuroNER

Given that TNER specializes in fine-tuning transformer-based language models for NER with a focus on cross-domain evaluation, and NeuroNER is a general neural network-based NER tool that predates widespread transformer adoption, they are primarily competitors in the broader NER space, with TNER offering a more modern, transformer-centric approach that likely provides superior performance for current tasks while NeuroNER represents an older, albeit still functional, paradigm.
