Lingva Translate is an alternative front-end for Google Translate, serving as a Free and Open Source translator with over a hundred languages available. Inspired by projects like Piped, Nitter, Invidious or Bibliogram, Lingva scrapes through Google Translate and retrieves the translation without directly accessing any Google-related service, preventing them from tracking. In this step by step guide I will show you how to install Lingva Translate on your Synology NAS using Docker & Portainer.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

• STEP 3

Make sure you have a synology.me Wildcard Certificate. Follow my guide to get a Wildcard Certificate. If you already have a synology.me Wildcard certificate, skip this STEP.

• STEP 4

Go to Control Panel / Login Portal / Advanced Tab / click Reverse Proxy. Follow the instructions in the image below.

• STEP 5

Now click the “Create” button. Follow the instructions in the image below.

• STEP 6

After you click the Create button, the window below will open. Follow the instructions in the image below.

On the General area, set the Reverse Proxy Name description: type in Lingva. After that, add the following instructions:

Check Enable HSTS

Destination:
Protocol: HTTP
Hostname: localhost

• STEP 7

On the Reverse Proxy Rules click the Custom Header tab. Click Create and then, from the drop-down menu, click WebSocket. After you click on WebSocket, two Header Names and two Values will be automatically added. Click Save. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

    hostname: lingva
    mem_limit: 2g
    cpu_shares: 768
    security_opt:
      - no-new-privileges:true
    ports:
      - 6455:3000
    environment:

Note: Before you paste the code above in the Web editor area below, change the value for site_domain and type in your own synology.me DDNS that you have previously created at STEP 6 without https:// at the beginning.

• STEP 12

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 15

Now open your browser and type in your HTTPS/SSL certificate like this https://lingva.yourname.synology.me that you have previously created at STEP 6. In my case it’s https://lingva.mariushosting.synology.me Type in a text and choose the language in which you would like to translate it, then click the lightning button. Follow the instructions in the image below.

• STEP 16

A hundred languages available!

Enjoy Lingva Translate!
