📖 What is this?

AI DevSec Gateway is an enterprise-grade, open-source proxy and DevSecOps tool that intercepts, audits, and routes AI traffic leaving your local machine.

Originally created as a simple GUI to block AI endpoints, it has evolved into a comprehensive Zero-Trust Gateway. It empowers developers and security teams to monitor exactly what data their AI coding assistants (like Copilot, Cursor, or extensions) are exfiltrating, intercept those requests, and route them to private, local, or corporate LLMs.

1. Intercept & Block: A deterministic OS-level override via the hosts file that drops unauthorized outbound connections to 38+ AI domains.
2. Route: A transparent local HTTP proxy that intercepts cloud API requests and reroutes them to local LLMs (like Ollama, LM Studio, or vLLM).
3. Audit: Real-time semantic analysis of active development environments to prevent data leakage and proprietary logic exposure.

✨ Features

Feature	Description
🔀 Transparent API Router	Seamlessly reroute Copilot/Cursor HTTP traffic to your own Local LLM inference servers.
🛡️ AI DevSec Auditor	Live, socket-level analysis of running processes to detect telemetry leaks. Powered by on-demand OpenAI audits (Zero-Persistence).
💻 Native CLI Interface	Full headless control for CI/CD environments. Use ai-blocker --status or ai-devsec-gateway --block.
🔒 Deterministic Kill Switch	Hard OS-level blocking (127.0.0.1 redirection). No ambiguity, no reliance on DNS filtering servers.
📦 Universal Distribution	Install via pip, brew, scoop, or as a portable single-file binary for Windows/Linux/macOS.
🌍 Multilingual GUI	A premium Catppuccin Mocha interface with 10 supported languages and smart OS elevation (UAC/sudo).

🏗️ Architecture

AI DevSec Gateway operates at the boundary between your local development environment and the cloud.

🚀 Quick Start

1. Python Package (Pip)

The fastest way to get started with the headless CLI.

pip install ai-devsec-gateway

# Native CLI commands are now available globally:
ai-blocker --status
ai-devsec-gateway --block
ai-devsec-gateway --unblock

2. Package Managers (macOS & Windows)

macOS (Homebrew):

brew tap Akunimal/ai-devsec-gateway https://github.com/Akunimal/AI-Router-Blocker-AiO
brew install ai-devsec-gateway
sudo ai-blocker --status

Windows (Scoop):

scoop bucket add ai-devsec-gateway https://github.com/Akunimal/AI-Router-Blocker-AiO.git
scoop install ai-devsec-gateway
ai-blocker --status

3. Portable GUI Binaries

If you prefer a rich visual interface without installing Python:

1. Visit the Releases page.
2. Download the executable for your OS (.exe, macOS binary, or Linux AppImage).
3. Run the application (it will automatically request Admin/sudo privileges when toggling the network switch).

🔒 Security Model

• Zero-Persistence BYOK: API keys for the semantic DevSec auditor are strictly kept in-memory. They are never written to disk, preventing supply-chain credential theft.
• Surgical OS Modifications: The engine uses targeted sed-like parsing to inject # AI-Block markers into the OS hosts file. It guarantees absolute isolation from your existing DNS mappings.
• Isolated Telemetry: The application itself contains absolutely zero tracking, analytics, or hidden background phone-home mechanics.

---

🤝 Open Source & Governance

We believe that security tools must be 100% transparent. This project is built under strict open-source governance:

• Architecture Guide: Complete technical specifications.
• Contributing Guide: Standards and PR templates.
• Code of Conduct: We foster a welcoming community.
• Security Policy: Responsible vulnerability disclosure.
• License: MIT Licensed.

🗺️ Roadmap & Future Vision

We are actively evolving towards an enterprise Zero-Trust DLP Engine. Upcoming milestones include:

• Real-Time DLP Sanitization: On-the-fly regex and heuristics to strip PII before routing.
• eBPF Kernel Telemetry: Detecting .git/config exfiltration directly at the Linux kernel level.
• Confidential Computing: Running the Gateway within Trusted Execution Environments (TEEs) like Intel SGX.

Explore our ROADMAP.md to see the full vision.
