A cross-platform LLM chat client — supports OpenAI, Claude, Gemini, Ollama, Groq, and more, with desktop builds via Tauri and Vercel-hostable web deployments.

What it is

A TypeScript + Next.js chat application that fronts the major LLM providers (OpenAI, Claude, Gemini, Groq, local-via-Ollama) plus a Tauri-packaged desktop build. One-click Vercel deploy for the web variant. Aimed at users who want one polished chat client across providers rather than installing one app per LLM.

Key features

Multi-provider: OpenAI, Anthropic Claude, Google Gemini, Groq, Ollama (local), Azure OpenAI.
Web + desktop (Tauri) + iOS / Android / Linux / Windows / macOS distributions.
Prompt-mask system (saved system prompts as personas).
Plugin / tool integration.
One-click Vercel deploy as the easy hosting path.
MIT-licensed.

Tech stack

TypeScript primary.
Next.js for the web app.
Tauri for desktop builds.

When to reach for it

You want one chat client across multiple LLM providers.
You're deploying internal chat tooling and want a clone-and-config-on-Vercel solution.

When not to reach for it

You want vendor-supported chat — go to the vendor's official apps (ChatGPT, Claude.ai, Gemini).
You want enterprise SSO / audit — those are commercial features in vendor-managed tools.

Maturity signal

88k stars, 60k forks, MIT, actively maintained. 60k forks reflect the "one-click deploy on Vercel" pattern — every user who deploys forks.

Alternatives

Vendor official apps.
open-webui/open-webui — heavier feature set, self-hosted-first.
LibreChat — strict-OSI alternative.
