[!IMPORTANT] Disclaimer: DLX is an independent, open-source project. It is not an official DeepL product, and it is not affiliated with, endorsed by, or sponsored by DeepL SE in any way. "DeepL" is a registered trademark of DeepL SE. Any reference to DeepL in this repository is made solely to describe interoperability with the DeepL translation service.
In July 2026, we received a trademark notice forwarded by GitHub Trust & Safety, submitted on behalf of DeepL SE. The notice stated that this project's former name, "DeepLX", contained the registered trademark "DeepL" and might cause confusion about whether the project is authorized or endorsed by DeepL SE.
It never was, and it never claimed to be. To resolve the matter and remove any possible confusion, we renamed the repository to DLX and removed DeepL branding from the project. To state it plainly one more time: this project is not an official DeepL project and has no relationship with DeepL SE whatsoever.
DLX is a self-hosted translation API server written in Go. It exposes a simple HTTP API on port 1188.
