LibreChat is an open-source Web UI written in JavaScript, with a website and demo available on the official website. To learn how to install LibreChat and utilize the OpenAI API for ChatGPT 4 and DALL-E 3 in a pay-as-you-go model, refer to this guide. Speech recognition can be configured to use Whisper, but only in a local installation. Additionally, there is an option to analyze images with GPT-4 and Gemini Vision, with a particular focus on the use of the OpenAI Assistants API. To utilize all options and a variety of different models, the self-host/local installation using Docker is necessary.

Chatbox AI provides a completely free web interface and is currently one of my favorites.

Chatbot UI project, found in the mckaywrigley/chatbot-ui repository on GitHub, is a self-hosted application developed in JavaScript. Its public web interface available is merely a demo, lacking full functionality. The user interface (UI) is not feature-rich compared to Chatbox AI, for example. Supports various APIs including OpenAI, Anthropic, Google Gemini, Mistral, Groq, Perplexity, and OpenRouter.

Anse izgleda odlično i open-source self-hosted. Repo na anse-app/anse: Supercharged experience for ChatGPT, DALL-E and Stable Diffusion.. Ništa posebno ne nudi jer je skoro identičan kao ChatGPT, ali pošto koristi API, onda je jeftiniji, a i u pitanju je Web app.
