DeLingo is an online translation and translation API tool. The site provides a web-based text translation interface and also presents JSON API documentation for developers. Its core capabilities include language detection and multilingual translation, with support for English, Japanese, Spanish, French, German, Italian, Portuguese, Korean, Chinese, Chinese Simplified, Chinese Traditional, Russian, Arabic, Hindi, Indonesian, Thai, Vietnamese, Turkish, Dutch, Swedish, and more.
Based on the documentation, DeLingo’s API design is lightweight: call https://delingo.net/v1/translate, pass the API key via X-Delingo-API-Key, and include text and target_lang in the request body. The response returns source_lang, target_lang, and translation. In the example, the Japanese sentence “こんにちは、元気ですか？” is translated into English as “Hello, how are you?”. This suggests it is suitable for quick integration into apps, websites, or internal tools for translating messages, short text, and multilingual content. The web input box shows a 5000-character limit, but it is not clear whether the same limit applies to the API.
The pricing page currently only shows “In development”, with no public plans, usage-based pricing, free quota, or trial rules. The documentation includes YOUR_DEMO_API_KEY, which suggests a demo key may exist, but the method for obtaining it and any restrictions are not disclosed. For Chinese support, the language list explicitly includes Chinese, Chinese Simplified, and Chinese Traditional, indicating support for Chinese and both simplified and traditional translation. However, there is no visible Chinese interface, Chinese documentation, or Chinese-language customer support information.
The main advantages are its simple API, standard JSON responses, and low learning curve for developers. It supports a fairly broad range of languages and offers basic language detection. The main weakness is limited transparency: it does not specify the underlying AI model or translation engine, and it lacks production-grade details such as glossaries, batch translation, error codes, rate limits, SDKs, and SLA information. Data privacy, log retention, and whether input content is used for training are also not disclosed. As for translation quality, the site only provides a simple example, making it difficult to evaluate performance on long-form text, specialized domains, complex Chinese contexts, or low-resource languages.
DeLingo is best suited for individual developers, small product teams, or prototype-stage multilingual feature integration where a translation API needs to be tested quickly. For enterprise production use, it is advisable to confirm pricing, stability, privacy compliance, and support options first. The main content does not provide information about access from mainland China, so real-world availability, network latency, and payment methods are unknown. If you need more mature alternatives, consider comparing it with DeepL API, Google Cloud Translation, Microsoft Translator, as well as Baidu Translate Open Platform, Youdao Zhiyun, and Volcano Translation.
