Hallucinet Explorer

An Electron-based web browser where every page is generated by an LLM. Instead of fetching real web content, all HTTP/HTTPS requests are intercepted and sent to a configured language model, which responds as if it were an HTTP server. The result is rendered in the browser exactly like a real web page.

Zero real HTTP requests leave the app (except to the LLM API endpoint itself).

Features

• Tabbed browsing — multiple tabs with independent navigation history
• LLM-generated pages — every URL produces unique, AI-hallucinated content
• Response caching — SQLite-backed cache so revisiting pages is instant
• Cookie support — RFC 6265-compliant simulated cookie jar across tabs
• Browsing history — searchable, paginated history at llm://history
• Redirect support — follows 3xx redirects (up to 10 hops)
• Reprompt — force a fresh LLM generation for any URL
• Settings UI — configure provider, model, system prompt, and more at llm://settings
• 542 error page — friendly error display when the LLM fails

Prerequisites

• Node.js (v18+)
• npm

Architecture

Main Process (Node.js)
├── LLM Client          — provider abstraction + API calls
├── Request Interceptor  — intercepts ALL outbound requests
├── HTTP Response Parser — lenient parser for LLM output
├── Cookie Jar           — RFC 6265 cookie store (SQLite)
├── Cache Manager        — disk-backed response cache (SQLite)
├── History Manager      — browsing history (SQLite)
└── Settings Manager     — persistent settings (SQLite)

Renderer Process (Chromium)
├── Browser Chrome UI    — address bar, tabs, navigation buttons
└── WebContentsView      — one per tab, renders LLM-generated HTML
