Open WebUI + Gonka AI - your own ChatGPT

Open WebUI is the most popular self-hosted ChatGPT interface. Beautiful UI, chat history, multimodal support, RAG, custom prompts, support for many models. Can be deployed in 5 minutes via Docker.

Open WebUI supports OpenAI-compatible APIs. By connecting JoinGonka Gateway, you get a full-fledged ChatGPT alternative for your team—for $0.001/1M tokens. The Gateway also supports the Anthropic API (/v1/messages), extending compatibility with ecosystem tools. No subscriptions ($20/month for ChatGPT Plus), no limits, full control over your data.

Step 1: Get API Key and Deploy Open WebUI

API Key: register at gate.joingonka.ai/register, get 10M free tokens, create a jg-xxx key.

Open WebUI Docker installation:

docker run -d \
  --name open-webui \
  -p 3000:8080 \
  -e OPENAI_API_BASE_URL=https://gate.joingonka.ai/v1 \
  -e OPENAI_API_KEY=jg-your-key \
  -v open-webui:/app/backend/data \
  ghcr.io/open-webui/open-webui:main

Open http://localhost:3000 - Open WebUI is ready to go.

Without Docker: if Docker is not installed, Open WebUI can be deployed via pip:

pip install open-webui
OPENAI_API_BASE_URL=https://gate.joingonka.ai/v1 \
  OPENAI_API_KEY=jg-your-key \
  open-webui serve

Step 2: Configure via UI

If you deployed Open WebUI without env variables, configure via the interface:

  1. Open Open WebUI → Create an administrator account.
  2. Go to Admin PanelSettingsConnections.
  3. In the OpenAI API section:
    • API URL: https://gate.joingonka.ai/v1
    • API Key: jg-your-key
  4. Click Save.
  5. In the model, select Qwen/Qwen3-235B-A22B-Instruct-2507-FP8.

For your team: create accounts for colleagues. Each gets their own chat interface, history, personal prompts - but all use one API key and one JoinGonka balance.

Features:

  • Markdown rendering with code highlighting
  • Document upload for analysis (RAG)
  • Custom system prompts
  • Export/import chats
  • Mobile interface
