ChatGPT client for developers who'd rather not pay, log in, or use VPNs

What it does

ShellGPT is a cross-platform desktop and web client that wraps ChatGPT, GPT-4, New Bing, Claude, and AI image generation behind a single interface. It targets users who want to avoid API keys, user accounts, and VPNs, routing traffic through a pool of relay nodes that automatically switch based on real-time speed tests. The app also offers unlimited-length translation, document chat, text polishing, and a plugin system for adding custom nodes.

The interesting bit

The project is essentially a smart reverse-proxy browser with a built-in node health checker. Instead of leaving users to hunt for working mirrors, it continuously measures latency across its relay pool and silently hops to the fastest node—an approach that matters most for users in regions with restricted access.

Key highlights

• Claims to work inside mainland China without a VPN (“国内免翻”)
• No API key or user account required for the default relay mode
• Supports GPT-4, Claude, New Bing, and AI drawing
• Automatic multi-node speed measurement and switching
• Cross-platform: Windows, macOS, Linux, Android, and web PWA
• Plugin system for inserting custom nodes or extensions
• Optional official API key entry via reverse proxy for users who have one
• Four specialized modes: dialogue, translation, unlimited long-text translation, and text polishing

Caveats

• The README tells macOS users to disable Gatekeeper or override malware warnings, indicating the binaries are not signed by a trusted Apple developer
• The project relies on unexplained third-party relay nodes; the README does not disclose who operates them, what data is logged, or how free access is sustained
• “Unlimited” and “free” claims depend on the continued availability of these relay endpoints, which is not addressed

Verdict

Grab it if you want a zero-setup ChatGPT client and are comfortable routing prompts through unknown relays. If code signing, data privacy, or long-term stability matters to you, use the official APIs instead.
