Argos Translate vs LibreTranslate

Self-host pick — both replace DeepL (Machine translation API).

Both Argos Translate and LibreTranslate self-host as a replacement for DeepL (Machine translation API). Pick Argos Translate if you want a MIT-licensed codebase (MIT); pick LibreTranslate for AGPL (AGPL-3.0). Both run in roughly the same cost bracket — $0 on a workstation; ~$10/mo for a small vps for batch jobs vs $10-30/mo vps — cpu-only works for low traffic; gpu recommended above 100 req/min.

Good fit for

Argos Translate

Batch translation pipelines (subtitle files, document translation jobs) where you don't need an HTTP service.

Weak at:No HTTP API by default; you build the service layer if you need one (or use LibreTranslate).

LibreTranslate

Web apps that want a self-hosted translation API for user content (UGC translation, support ticket I18n).

Weak at:Quality on rare pairs (EN ↔ Slavic, EN ↔ Asian) is below DeepL; for high-stakes translation this still matters.

In a terminal? npx -y github:SolvoHQ/os-alt-cli deepl prints DeepL's self-host options including both — how the CLI works →
