DeepL Free vs. Pro
The plugin supports both DeepL API plans. The Free API is the default; switch under Settings > System > Translation with DeepL > Use DeepL Free API (disable when using a Pro key).
| Free API | Pro API | |
|---|---|---|
| Base URL | api-free.deepl.com |
api.deepl.com |
| Quota | Limited characters per month | Depends on the booked package |
| Data processing | DeepL free plan terms apply | DeepL states that texts are not used to train models |
| Plugin automatic 429 retry | Yes | Yes |
Worth knowing:
- The plugin automatically selects the correct base URL based on this setting. A free key against the Pro URL (or vice versa) fails with an authentication error.
- The current quota usage is shown under Content > Translation with DeepL > DeepL Usage.
- Privacy: the plan differences can matter for your GDPR assessment, see Configuration: privacy.
- Current terms and limits of both plans: deepl.com/pro-api.
