RA.Aid - Develop software autonomously.

Python Versions License Status

Develop software autonomously.

RA.Aid (pronounced "raid") helps you develop software autonomously. It is a standalone coding agent built on LangGraph's agent-based task execution framework. The tool provides an intelligent assistant that can help with research, planning, and implementation of multi-step development tasks. RA.Aid can optionally integrate with aider (https://aider.chat/) via the --use-aider flag to leverage its specialized code editing capabilities.

The result is near-fully-autonomous software development.

Web Research

RA.Aid Demo

The agent features autonomous web research capabilities powered by the Tavily API, seamlessly integrating real-world information into its problem-solving workflow. Web research is conducted automatically when the agent determines additional context would be valuable - no explicit configuration required.

For example, when researching modern authentication practices or investigating new API requirements, the agent will autonomously:

  • Search for current best practices and security recommendations
  • Find relevant documentation and technical specifications
  • Gather real-world implementation examples
  • Stay updated on latest industry standards

While web research happens automatically as needed, you can also explicitly request research-focused tasks:

# Focused research task with web search capabilities
ra-aid -m "Research current best practices for API rate limiting" --research-only

Make sure to set your TAVILY_API_KEY environment variable to enable this feature.

Chat Mode

Chat Mode Demo

Enable with --chat to transform ra-aid into an interactive assistant that guides you through research and implementation tasks. Have a natural conversation about what you want to build, explore options together, and dispatch work - all while maintaining context of your discussion. Perfect for when you want to think through problems collaboratively rather than just executing commands.

Server with Web Interface

RA.Aid includes a modern server with web interface that provides:

  • Beautiful dark-themed chat interface
  • Real-time streaming of agent trajectory
  • Responsive design that works on all devices

To launch the server with web interface:

# Start with default settings (0.0.0.0:1818)
ra-aid --server

# Specify custom host and port
ra-aid --server --server-host 127.0.0.1 --server-port 3000

Command line options for server with web interface:

  • --server: Launch the server with web interface
  • --server-host: Host to listen on (default: 0.0.0.0)
  • --server-port: Port to listen on (default: 1818)

After starting the server, open your web browser to the displayed URL (e.g., http://localhost:1818).

Command Interruption and Feedback

Command Interrupt Demo

You can interrupt the agent at any time by pressing Ctrl-C. This pauses the agent, allowing you to provide feedback, adjust your instructions, or steer the execution in a new direction. Press Ctrl-C again if you want to completely exit the program.

Shell Command Automation with Cowboy Mode 🏇

The --cowboy-mode flag enables automated shell command execution without confirmation prompts. This is useful for:

  • CI/CD pipelines
  • Automated testing environments
  • Batch processing operations
  • Scripted workflows
ra-aid -m "Update all deprecated API calls" --cowboy-mode

⚠️ Important Safety Notes:

  • Cowboy mode skips confirmation prompts for shell commands
  • Always use in version-controlled repositories
  • Ensure you have a clean working tree before running
  • Review changes in git diff before committing

Model Configuration

RA.Aid supports multiple AI providers and models. The default model is Anthropic's Claude 3 Sonnet (claude-3-7-sonnet-20250219).

When using the --use-aider flag, the programmer tool (aider) automatically selects its model based on your available API keys. It will use Claude models if ANTHROPIC_API_KEY is set, or fall back to OpenAI models if only OPENAI_API_KEY is available.

Note: The expert tool can be configured to use different providers (OpenAI, Anthropic, OpenRouter, Gemini) using the --expert-provider flag along with the corresponding EXPERT_*API_KEY environment variables. Each provider requires its own API key set through the appropriate environment variable.

Environment Variables

RA.Aid supports multiple providers through environment variables:

  • ANTHROPIC_API_KEY: Required for the default Anthropic provider
  • OPENAI_API_KEY: Required for OpenAI provider
  • OPENROUTER_API_KEY: Required for OpenRouter provider
  • DEEPSEEK_API_KEY: Required for DeepSeek provider
  • OPENAI_API_BASE: Required for OpenAI-compatible providers along with OPENAI_API_KEY
  • GEMINI_API_KEY: Required for Gemini provider

Expert Tool Environment Variables:

  • EXPERT_OPENAI_API_KEY: API key for expert tool using OpenAI provider
  • EXPERT_ANTHROPIC_API_KEY: API key for expert tool using Anthropic provider
  • EXPERT_OPENROUTER_API_KEY: API key for expert tool using OpenRouter provider
  • EXPERT_OPENAI_API_BASE: Base URL for expert tool using OpenAI-compatible provider
  • EXPERT_GEMINI_API_KEY: API key for expert tool using Gemini provider
  • EXPERT_DEEPSEEK_API_KEY: API key for expert tool using DeepSeek provider

You can set these permanently in your shell's configuration file (e.g., ~/.bashrc or ~/.zshrc):

# Default provider (Anthropic)
export ANTHROPIC_API_KEY=your_api_key_here

# For OpenAI features and expert tool
export OPENAI_API_KEY=your_api_key_here

# For OpenRouter provider
export OPENROUTER_API_KEY=your_api_key_here

# For OpenAI-compatible providers
export OPENAI_API_BASE=your_api_base_url

# For Gemini provider
export GEMINI_API_KEY=your_api_key_here

Custom Model Examples

  1. Using Anthropic (Default)

    # Uses default model (claude-3-7-sonnet-20250219)
ra-aid -m "Your task"

# Or explicitly specify:
ra-aid -m "Your task" --provider anthropic --model claude-3-5-sonnet-20241022

  2. Using OpenAI

    ra-aid -m "Your task" --provider openai --model gpt-4o

  3. Using OpenRouter

    ra-aid -m "Your task" --provider openrouter --model mistralai/mistral-large-2411

  4. Using DeepSeek

    # Direct DeepSeek provider (requires DEEPSEEK_API_KEY)
ra-aid -m "Your task" --provider deepseek --model deepseek-reasoner

# DeepSeek via OpenRouter
ra-aid -m "Your task" --provider openrouter --model deepseek/deepseek-r1

  5. Configuring Expert Provider

    The expert tool is used by the agent for complex logic and debugging tasks. It can be configured to use different providers (OpenAI, Anthropic, OpenRouter, Gemini, openai-compatible) using the --expert-provider flag along with the corresponding EXPERT_*API_KEY environment variables.

    # Use Anthropic for expert tool
export EXPERT_ANTHROPIC_API_KEY=your_anthropic_api_key
ra-aid -m "Your task" --expert-provider anthropic --expert-model claude-3-5-sonnet-20241022

# Use OpenRouter for expert tool
export OPENROUTER_API_KEY=your_openrouter_api_key
ra-aid -m "Your task" --expert-provider openrouter --expert-model mistralai/mistral-large-2411

# Use DeepSeek for expert tool
export DEEPSEEK_API_KEY=your_deepseek_api_key
ra-aid -m "Your task" --expert-provider deepseek --expert-model deepseek-reasoner

# Use default OpenAI for expert tool
export EXPERT_OPENAI_API_KEY=your_openai_api_key
ra-aid -m "Your task" --expert-provider openai --expert-model o1

# Use Gemini for expert tool
export EXPERT_GEMINI_API_KEY=your_gemini_api_key
ra-aid -m "Your task" --expert-provider gemini --expert-model gemini-2.0-flash-thinking-exp-1219

Aider specific Environment Variables you can add:

  • AIDER_FLAGS: Optional comma-separated list of flags to pass to the underlying aider tool (e.g., "yes-always,dark-mode")
# Optional: Configure aider behavior
export AIDER_FLAGS="yes-always,dark-mode,no-auto-commits"

Note: For AIDER_FLAGS, you can specify flags with or without the leading --. Multiple flags should be comma-separated, and spaces around flags are automatically handled. For example, both "yes-always,dark-mode" and "--yes-always, --dark-mode" are valid.

Important Notes:

  • Performance varies between models. The default Claude 3 Sonnet model currently provides the best and most reliable results.
  • Model configuration is done via command line arguments: --provider and --model
  • The --model argument is required for all providers except Anthropic (which defaults to claude-3-7-sonnet-20250219)

More information is available in our Open Models Setup guide.
