Should I self-host DeepL Pro?
KINDAworth it if…
LibreTranslate gives you an unlimited private translation API for the cost of a beefy-ish container. The honest gap: open models still trail DeepL noticeably on nuance. Worth it for bulk/private pipelines; not if translation quality is customer-facing.
The math (nothing hidden, including your time)
| DeepL Pro (Individual) | $8.74/mo |
| VPS share + storage | −$1.00/mo |
| Your maintenance: 15 min/mo at $20/h | −$5.00/mo |
| Net saving | $2.74/mo |
| Setup: 15 min measured (one-time) | $5.00 |
| Break-even | 1.8 months |
| Markup Index (price ÷ real self-host cost) | 1.5× |
