-Jina provides [a family of `Executor` classes](https://github.com/jina-ai/jina/tree/master/docs/chapters/101#the-executor-family), which summarize frequently-used algorithmic components in neural search. This family consists of encoders, indexers, crafters, evaluators, and classifiers, each with a well-designed interface. You can find the list of [all 107 built-in executors here](https://docs.jina.ai/chapters/all_exec.html). If they don't meet your needs, inheriting from one of them is the easiest way to bootstrap your own Executor. Simply use our Jina Hub CLI:
