⚔️ RoninAgent — Open Source Autonomous AI Agent

⭐ Star Us on GitHub! If you find RoninAgent useful or inspiring, please consider giving this repository a star! It helps the project grow and fuels future development. 🚀

Note

Rebranding Notice: RoninAgent was formerly known as OpenPAIAgent (Open Personal AI Agent). Same lightning-fast, zero-bloat architecture — now with a stronger sovereign identity.

RoninAgent project page

RoninAgent is a high-speed, zero-bloat open-source personal AI agent built for absolute privacy, local execution, and total autonomy. Designed as an ultra-lightweight alternative to resource-heavy frameworks, it drops complex abstractions like LangChain in favor of pure TypeScript performance, sub-second cold starts, and complete data sovereignty.

Tip

🌍 Built for markets Western agents can't read. Out of the box RoninAgent understands Wildberries, Ozon, List.am (Armenia), Temu and Amazon — each skill carries that marketplace's real URL structure, price-sorting parameters and parsing rules, so the agent can actually pull and compare live listings. Trigger keywords are bilingual (wildberries / вайлдберриз, ozon / озон, list.am / лист ам), so you can ask in English or Russian.

⚡Features

• 💬 Dual Interfaces: A beautiful cyberpunk-themed Web UI + Remote chat access via a Telegram bot.
• 🤖 Multi-Agent Hub: Dedicated in-app Agents Hub manager to create, edit, switch, and delete custom AI agents. Easily tweak persona files (Agent.md, Identity.md, User.md, Memory.md) and tailor prompt instructions for each specialized agent.
• 🧠 Modular System Prompt: The agent's personality and instructions are compiled dynamically from simple Markdown files (Agent.md, Identity.md, User.md, Memory.md).
• ⚡ Dynamic Agent Skills: Save LLM context tokens by loading specialized prompt instructions conditionally. Shared skills live in skills/*.md (with optional agent-specific overrides in agents/<agentId>/skills/*.md). When a query matches header keywords (e.g., Keywords: amazon, wildberries, temu, code), instructions are dynamically injected into the system prompt. Comes with pre-built skills for:
  • 🛒 Regional E-commerce & Local Search: Marketplace-specific URL structures, price sorting, and parsing rules for Wildberries, Ozon, List.am (Armenia), Temu, and Amazon — with bilingual EN/RU trigger keywords.
  • 💻 Software Engineering: Refactoring, debugging, and strict code style instructions.
  • 🎨 Content Writing & Design: Copywriting, UI/UX guidelines, and image generation prompt optimization.
• 👁️ AI Vision & Document Analysis: Attach images or upload documents directly in the chat. Features auto-optimization for images via sharp and native parsing for documents (PDF, Word, Excel, Text/CSV/JSON).
• 🔧 Powerful Tool Execution (Function Calling):
  • 📄 Full File & Document Lifecycle (Read & Write): Full read, create, update, and deletion support for multiple document types within the dedicated local workspace/ folder:
    • Read & Analyze: Text/Markdown/Code/JSON/CSV, PDF documents (.pdf), Word documents (.docx, .doc), and Excel spreadsheets (.xlsx, .xls with multi-sheet inspection).
    • Generate & Create: Generate structured Excel spreadsheets (.xlsx) with custom columns, row styling, and formulas; build styled Word documents (.docx) with headings and tables; render custom HTML/CSS into professional A4 PDF documents; and create/update text/code files.
  • Web Scraper: Downloads pages, strips out bloated HTML, and cleans the text for real-time AI analysis. Supports both fast static scraping and dynamic rendering with automatic fallback for SPAs (like React, Vue, e-commerce sites).
  • Image Generation: Generates images using Together AI or X.AI (Grok) APIs directly in the chat, with smart fallback logic (if one provider is not configured, it automatically uses the other).
• 💾 Semantic Memory (SQLite + Vectors): Saves chat sessions and history using SQLite, with support for semantic vector search via the lightweight sqlite-vec extension.
• 📋 Task Management & Scheduler: Schedule automated background tasks or trigger them manually. Features an automatic background task runner (scans every 60s), real-time status tracking in the UI, and instant Telegram execution alerts.

🧠 Key Architectural Decisions

RoninAgent is built with a clear focus on lightweight, efficient, and transparent AI engineering:

• Why No LangChain / LlamaIndex?
  • Complete State Control: The agent's cognitive loop (think-act-evaluate) is written in vanilla TypeScript, ensuring complete control over LLM tool-calling and historical state.
  • Sub-Second Boot: The backend starts in < 1 second and consumes a minuscule ~50-100 MB of RAM.
  • Auditability: Clean, readable code without nested abstractions makes debugging prompts and tools trivial.
• Smart Hybrid RAG & Memory:
  • Uses a local SQLite database combined with the lightweight sqlite-vec extension for vector embeddings.
  • Combines semantic vector similarity search with keyword fallback (LIKE queries), providing high-recall context retrieval with zero external database dependencies (no pgvector, Qdrant, or Pinecone required).

💡 What is this project for?

This project is designed for anyone who wants a personal AI assistant that can seamlessly process documents (read & create PDF, Word, Excel, and text files), browse the web, generate images, and communicate smoothly through a slick web interface or remotely on-the-go via a Telegram bot.

🔒 100% Self-Hosted & Private

RoninAgent runs entirely on your local machine or private server. All chat history, settings, and workspace documents are stored in a local SQLite database. Your private data never leaves your computer, and you retain absolute control over which external APIs (like OpenRouter or Together AI) are called.

🔓 Fully Open Source

Built with clean TypeScript and vanilla web technologies under the MIT license. No massive, opaque frameworks (like LangChain) or hidden tracking. You have full transparency, can easily audit the source code, and can freely modify or extend the agent's tools and behaviors.

⚙️ Setup & Installation

Prerequisites

• Node.js (v20.x or later)
• npm (v9.x or later)

1. Clone & Install Dependencies

git clone https://github.com/nordevelopment/RoninAgent
cd RoninAgent
npm install

(Alternatively, you can download and extract the ZIP archive directly from GitHub).

2. Configuration & Launch

Configuration can be set up beforehand via a .env file or configured interactively via the Web Setup Wizard on first launch.

# Start - Build & launch the server
npm start

Once started, open http://127.0.0.1:3000 in your browser. If no configuration is detected, you will be automatically redirected to the setup wizard. You can also adjust settings later via the Settings page in the UI.

🛠️ For Developers

# Run the development server (with hot reloading)
npm run dev

# Recreate/reset the SQLite database schema
npm run db:reset

# Run build only
npm run build

🔒 Security

RoninAgent includes built-in security features to protect your server, files, and API balances when deployed remotely. These security settings can be easily configured either during the first-launch setup wizard, or later at any time via the Web Settings Panel (/settings page in the UI).

Warning

Never expose port 3000 directly to the internet. HTTP Basic Auth sends your password in plain text — over an unencrypted connection anyone on the path can read it. For remote access, put RoninAgent behind a TLS reverse proxy, or reach it over a private network (Tailscale / WireGuard).

A complete Caddyfile — Caddy obtains and renews the certificate automatically:

agent.example.com {
    reverse_proxy 127.0.0.1:3000
}

Keep HOST=127.0.0.1 so only the proxy can reach the app, and set a strong APP_PASSWORD.

• HTTP Basic Auth: Lock the Web UI and API endpoints behind a password. Set APP_PASSWORD (and optionally APP_USER) in your .env (or via Settings UI) to enable it. Leaving APP_PASSWORD empty disables authentication (ideal for local localhost use); if you do that while binding to a non-loopback HOST, a warning is logged at startup.
• Brute-Force Protection: Credentials are compared in constant time, and 5 failed attempts from the same IP lock that IP out for 60 seconds (429 with a Retry-After header). Only failures are counted, so a legitimate session is never throttled.
• Telegram Bot Whitelist: Restrict access to your Telegram bot. Set ALLOWED_TELEGRAM_USER_IDS in your .env (or via Settings UI) with a comma-separated list of Telegram User IDs to prevent unauthorized users from using your bot and API balances.
• Strict Path Validation: All AI file operations (read, write, delete) are strictly validated using path.relative comparison to ensure the AI cannot escape or access files outside the designated workspace/ folder.
• Safe Agent Directory Routing: Directory operations on agent profiles (like editing files) sanitize all incoming IDs to prevent Path Traversal outside the agents/ folder.
• Secure Cookies & Sessions: Session IDs are generated using Node's cryptographically secure crypto.randomUUID() and session cookies are protected with sameSite: 'lax' and conditional secure flags.

⚖️ Comparison: RoninAgent vs. Heavyweight Alternatives

While other self-hosted AI interfaces require heavy setups (Docker, multi-container databases, etc.), RoninAgent is optimized for raw local performance and resource conservation:

• RAM Footprint: ~50-100 MB (compared to 1.5 GB+ for Open WebUI or 1 GB+ for LibreChat).
• Startup Time: Sub-second (< 1s) (compared to 30-60s boot times for Docker-based alternatives).
• Dependencies: Zero. Runs natively with just Node.js and npm.
• Database: Embedded SQLite. Supports semantic vector search directly via the loaded sqlite-vec library extension.
• Ideal For: Private on-the-go AI assistance, local file manipulation, and fast scraping workflows.
