With the current increase in globalization, there is a need for the development of translation services that can remove language barriers that normally hinder effective communication between people.
Fortunately, there are several translation software that have been developed to make the process of translating web pages, phrases, and words painless.
What’s more, some of the software have exposed their Application Programming Interfaces (APIs) to enable developers to integrate their features and incorporate translation capabilities into their own applications—without building them from scratch.
To assist you in making the best decision on the most suitable API to use, we reviewed several translation APIs based on the following four main criteria:
- API features: We evaluated the outstanding features of each of the translation APIs
- Supported languages: We assessed the languages that each of the APIs support.
- Pricing: We analyzed the cost of integrating each of the APIs into applications.
- Ease of use: We looked at the ease of using each of the APIs.
Eventually, we developed the following list of the top 10 best translation APIs:
- Google Translate API
- Microsoft Translation API
- Translate API
- Text Translation API
- SYSTRAN.io Translation API
- MyMemory Translation API
- My Translator Pro API
- Linguatools Translate API
- Yandex Translate API
- IBM Watson Language Translator API
