Lanquora is a free translation service. Use the homepage translator without an account, or create a developer account and a named API key to translate from your own application.
Developer accounts start with 10,000 API translations per UTC day, shared across their keys. If you need more, submit a free allowance request from your account. A higher allowance does not remove rate limits or create more server capacity.
The homepage accepts up to 4,000 characters and streams its results. The API accepts up to 768 UTF-8 bytes per translation. Read the documentation and integration guide before connecting a production application.
Language support and translation quality are different things. Some directions are experimental. Portuguese has returned the wrong language in tests; check the output carefully. Always review important translations for meaning, names, and tone.
This blog will carry service updates and practical notes. There are no paid plans. Please pace your requests so this shared service stays useful for everyone.
