How do I set up translation providers (DeepL, Google, Azure, Amazon)?

Better i18n supports multiple machine translation providers as alternatives or supplements to the built-in AI translation. Connect DeepL, Google Translate, Azure Translator, or Amazon Translate to use their engines.

Available providers

Provider	Best for	Pricing model
DeepL	High-quality European languages	Free tier + paid plans
Google Translate	Widest language support (130+)	Pay per character
Azure Translator	Enterprise, Microsoft ecosystem	Free tier (2M chars/month)
Amazon Translate	AWS ecosystem, batch translation	Pay per character

Setting up a provider

All providers follow the same setup pattern:

1. Go to your project → Integrations tab
2. Find the provider card (e.g., DeepL)
3. Click Install or Enable
4. Enter your API credentials
5. Click Save

DeepL

1. Get your API key from deepl.com/account
2. Enter the DeepL API Key in the configuration
3. Select Free or Pro API (different base URLs)

Google Translate

1. Create a project in Google Cloud Console
2. Enable the Cloud Translation API
3. Create a service account and download the JSON key
4. Paste the credentials in the configuration

Azure Translator

1. Create a Translator resource in Azure Portal
2. Copy your API Key and Region
3. Enter both in the configuration

Amazon Translate

1. Create an IAM user in AWS Console
2. Attach the TranslateFullAccess policy
3. Generate Access Key ID and Secret Access Key
4. Enter both in the configuration

Using providers

Once configured, translation providers appear as options when translating:

• In the AI translation drawer — select which engine to use
• Via API/MCP — specify the provider in translation requests
• Fallback chain — if the primary provider fails, others can be used as fallback

Provider vs. AI translation

	AI Translation (built-in)	Translation Providers
Engine	Google Gemini LLM	Machine translation APIs
Context-aware	Yes (glossary, guidelines, key names)	Limited
Quality	Higher for nuanced content	Good for straightforward text
Speed	Moderate	Very fast
Cost	Included in plan	Separate provider costs

Recommendation: Use AI translation for UI strings and important content. Use providers for bulk translation of simple, repetitive text.

Managing providers

• Go to Integrations → click the provider → Manage
• Disable — temporarily stop using a provider without removing credentials
• Update credentials — change API keys when they rotate
• Remove — completely disconnect the provider

Organization-level providers

Translation providers can also be configured at the organization level:

1. Go to Organization Settings → Connections
2. Configure LLM Providers for AI translation
3. These settings apply to all projects in the organization
