// EDITOR'S TAKE

Tabby is the direct equivalent, a self-hosted completion server you point your IDE at, which is the main reason teams buy Tabnine in the first place. Continue is more flexible if you want to mix models and shape autocomplete and chat behaviour yourself, while Cline and kilocode are a different generation of tool, agents that edit files and run commands rather than finishing your line.
