Chatbot UI

Chatbot UI is an open-source ChatGPT-style web frontend that supports custom OpenAI-compatible endpoints.

Official repository: https://github.com/mckaywrigley/chatbot-ui

Self-hosted deployment

For self-hosted instances, configure the custom endpoint via environment variables:

OPENAI_API_KEY=codex_your_api_key
OPENAI_API_HOST=https://codex.openai.com/v1

Restart the service after setting the variables. When environment variables are set, the corresponding UI input fields are disabled to prevent credential exposure on shared instances.

UI settings

For instances that allow UI configuration, fill in the settings panel:

Field	Value
OpenAI API Key	Your codex_... or sk-... key
OpenAI API Host / Base URL	https://codex.openai.com/v1

Notes

• Chatbot UI requires Supabase for authentication and data storage
• The API Host takes the base URL including /v1
• Available models can be found via GET /v1/models
