CNTRL Browser

Intent-based autonomous browsing

CNTRL Browser is a lightweight, AI-driven autonomous browser built with Tauri (Rust backend) and SolidJS (TypeScript frontend). It is designed to interpret natural language intents and execute them autonomously across the web.

Architecture Overview

• Runtime: Tauri v2
• Backend: Rust (Business logic, SQLite memory, OS Keychain, AI router, OS webview fallback)
• Frontend: SolidJS + TypeScript (State: Zustand/Solid stores, Styling: CSS custom properties)
• AI Tiers:
  • Tier 1 (Local): Ollama
  • Tier 2 (Freemium): Gemini Flash, Groq, Hugging Face
  • Tier 3 (Precision): OpenAI-compatible endpoints (Claude, GPT-4o, etc.)

7-Phase Build Plan

• Phase 1: Project Scaffold & CI Pipeline
• Phase 2: Webview Engine & Browser Chrome (Native fallback architecture)
• Phase 3: Hybrid Brain & Model Router (Ollama/OpenRouter/HF integration)
• Phase 4: Intent Layer & Command Bar (Natural Language Actions)
• Phase 5: Memory Engine & Security Layer
• Phase 6: Background Agents & Macro Recorder
• Phase 7: Design System, Plugin SDK & OSS Release

Getting Started

Prerequisites

• Node.js 20+
• Rust stable toolchain
• Tauri v2 prerequisites (OS-specific webview dev headers)

Run Locally

npm install
npm run tauri dev
