chat-ui and app
These are **competitors** — both are full-stack SvelteKit-based chat applications designed to provide open-source alternatives to proprietary LLM chat interfaces, with users choosing one based on maturity (HuggingChat's established codebase) versus performance claims (helioschat's "blazing-fast" optimization).
About chat-ui
huggingface/chat-ui
The open source codebase powering HuggingChat
This project helps you set up your own customizable chat interface for Large Language Models (LLMs) like those found in HuggingChat. You can connect it to various OpenAI-compatible API providers, whether they're local servers or cloud services, and get a functional chat application that runs in your web browser. This is for individuals or teams who want to host a private or branded AI chat experience.
About app
helioschat/app
Blazing-fast, private & open-source SvelteKit LLM chat app
This tool helps individuals engage with AI language models while ensuring their conversations remain private and secure. You input your questions or prompts, and the AI generates responses, all without your data ever leaving your browser or being stored on a central server. This is ideal for anyone who uses AI chat for sensitive topics, personal planning, or confidential work.
