The 2026-06-06 schema breaks v3.0 clients and drops BreakSentence and dictionary lookups from the spec.\n\n**LibreTranslate.** Open source under AGPL-3.0, self-hosted with no text leaving your network. No status page, SLA or terms of service for the hosted API.\n\n## Before you call either\n\n### Azure Translator\n\n1. Send `Ocp-Apim-Subscription-Region` with the key for a regional resource\n2. Pin `api-version=3.0` until your client handles the 2026-06-06 `inputs` and `value` shape\n3. Batch up to 1,000 strings a call rather than one call per string\n4. Spread load across the hour, since the character caps are hourly and bursts get 429\n5. Treat 403001 as the free quota running out, not a permissions error\n\n### LibreTranslate\n\n1. Split text into calls of 2,000 characters or fewer on the hosted service\n2. Pace to about 20 calls a minute on Pro, since repeated 429s turn into a 403 ban\n3. Pass `source=auto` to detect and translate in one call\n4. Set `format=html` for markup\n5. Read /spec on the server you call, since self-hosted limits and options differ from the hosted ones\n\n## Other comparisons with Azure Translator or LibreTranslate\n\n- [Amazon Translate vs Azure Translator](https://www.anchorterminal.com/compare/amazon-translate-vs-azure-translator.md)\n- [Amazon Translate vs LibreTranslate](https://www.anchorterminal.com/compare/amazon-translate-vs-libretranslate.md)\n- [Azure Translator vs DeepL API](https://www.anchorterminal.com/compare/azure-translator-vs-deepl-api.md)\n- [Azure Translator vs Google Cloud Translation](https://www.anchorterminal.com/compare/azure-translator-vs-google-cloud-translation.md)\n- [Azure Translator vs Lara Translate API](https://www.anchorterminal.com/compare/azure-translator-vs-lara-translate.md)\n- [Azure Translator vs Lingvanex Translation API](https://www.anchorterminal.com/compare/azure-translator-vs-lingvanex.md)\n- [DeepL API vs LibreTranslate](https://www.anchorterminal.com/compare/deepl-api-vs-libretranslate.md)\n- [Google Cloud Translation vs LibreTranslate](https://www.anchorterminal.com/compare/google-cloud-translation-vs-libretranslate.md)\n- [Lara Translate API vs LibreTranslate](https://www.anchorterminal.com/compare/lara-translate-vs-libretranslate.md)\n- [LibreTranslate vs Lingvanex Translation API](https://www.anchorterminal.com/compare/libretranslate-vs-lingvanex.md)\n",
