6 Enabling HTTPS Encryption

Secure Your Open WebUI with HTTPS 🔒

While HTTPS is not strictly required for basic local operation, it is highly recommended for all deployments and mandatory for enabling specific features like Voice Calls.

:::warning Critical Feature Dependency Modern browsers require a Secure Context (HTTPS) to access the microphone. Voice Calls will NOT work if you access Open WebUI via http:// (unless using localhost). :::

Why HTTPS Matters 🛡️

Enabling HTTPS encryption provides essential benefits:

  1. 🔒 Privacy & Security: Encrypts all data between the user and the server, protecting chat history and credentials.
  2. 🎤 Feature Unlocking: Enables browser restrictions for Microphone (Voice Mode) and Camera access.
  3. 💪 Integrity: Ensures data is not tampered with in transit.
  4. Trust: Displays the padlock icon, reassuring users that the service is secure.

Choosing Your Solution 🛠️

The best method depends on your infrastructure.

🏠 For Local/Docker Users

If you are running Open WebUI with Docker, the standard approach is to use a Reverse Proxy. This sits in front of Open WebUI and handles the SSL encryption.

  • Nginx: The industry standard. Highly configurable, great performance.
  • Caddy: Easiest option. Automatically obtains and renews Let's Encrypt certificates with minimal config.
  • HAProxy: Robust choice for advanced load balancing needs.

☁️ For Cloud Deployments

  • Cloud Load Balancers: (AWS ALB, Google Cloud Load Balancing) often handle SSL termination natively.
  • Cloudflare Tunnel: Excellent for exposing localhost to the web securely without opening ports.

🧪 For Development

  • Ngrok: Good for quickly testing Voice features locally. Not for production.
