FAQ
- Is it free?
- The LibreTranslate licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no DeepL seat or task bill on this path.
- Can I migrate from DeepL?
- Yes. Start with the workflows or data you actually use, then cut over. The LibreTranslate stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old DeepL links until they expire.
- How do I deploy it?
- Open the LibreTranslate stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: LibreTranslate plus a volume for language models. CPU is enough for light use; GPU is optional. No one-click template in this repo yet — Start on Railway. Grammar checking stays on /stacks/languagetool-writing.
- What does this replace?
- DeepL. The published small-team estimate on this stack is $1,200 a year.
