Loco Translate official plugin provides easy translation management for developers, but you can not auto translate all translatable strings without purchasing any auto-translate API subscription.

But if you install Loco Automatic Translate Addon along with Loco plugin then you can remove this limitation and you can translate your theme or plugin string into any language with one button click without any auto-translate API.

It supports Yandex, Google and DeepL Translate free translation widgets for unlimited automatic translations. This process will save your money and many hours of manual translation work.
