Built for Production AI Systems

Runtime-optimized authorization that identifies security issues at the code level, not just endpoints.

Code-Level Security

Decorated functions deny by default until explicitly authorized. Identifies auth problems at the code level, not just routes.

Fast Policy Updates

Policy changes propagate in under a minute across all environments. Plan-based polling ensures optimal performance.

One Decorator

Just add @d2_guard to your functions. Extremely simple code that replaces hundreds of lines of auth logic.

Local & Cloud Modes

Start with local file-based policies for development. Scale to cloud for production with zero code changes.

Rich CLI Tools

Built-in CLI for policy management, diagnostics, and inspection. Perfect developer experience.

Runtime Optimized

Built for high-performance production systems with minimal overhead and intelligent caching.

From Complex to Simple

Replace hundreds of lines of authorization logic with a single decorator.

Before D2

# Hundreds of lines of auth logic

def get_weather(user,location):

if not user:

raise PermissionError

if user.role not in ["admin", "weather"]:

raise PermissionError

if not validate_permissions(user):

raise PermissionError

# ... and more

return weather_service.fetch(location)

With D2

# Complete setup

@d2_guard("weather_api")

def get_weather(location: str):

return weather_service.fetch(location)

# Set context

set_user("alice", roles=["developer"])

# Clear when done

clear_user_context()
