What is Arch?
Arch is the universal dataplane designed for developers building sophisticated AI agents. It acts as an intelligent, AI-native gateway that handles the complex, low-level infrastructure—from security and routing to observability—so you can focus on creating powerful, enterprise-ready applications instead of wrestling with tedious backend plumbing.
Key Features
🛡️ Centralized Safety & Guardrails Apply critical safety measures like jailbreak prevention and interaction policies across your entire application without writing a single line of code. You can centrally define and enforce custom guardrails to ensure user interactions remain safe, on-topic, and aligned with your application's purpose.
🔄 Unified Multi-LLM Access Integrate, experiment with, and switch between over 100 different LLMs through a single, consistent interface. Arch centralizes access controls and provides high-throughput, resilient traffic management, giving you the freedom to use the best model for the job without vendor lock-in or complex integration work.
🧠 Intelligent Prompt & Task Routing Automatically direct user prompts to the most appropriate agent, tool, or API for maximum accuracy and efficiency. Arch uses its own purpose-built models to understand user intent, clarify requests, and route tasks intelligently, dramatically improving the performance of both simple and complex agentic workflows.
🔎 Standards-Based Observability Gain deep, actionable insights into your AI application's performance with rich, out-of-the-box telemetry. Arch generates detailed logs, metrics, and traces for all prompt and LLM interactions, which are fully compatible with OpenTelemetry destinations like Jaeger, Signoz, and Honeycomb for seamless monitoring.
🔌 Seamless Prompt-to-API Integration Effortlessly translate unstructured, free-form user requests into structured function calls. Arch manages the conversion of natural language into precise API calls for executing backend operations, allowing you to build agents that can take real-world action reliably and securely.
How Arch Solves Your Problems:
Arch is designed to help you move beyond simple demos and build sophisticated, production-grade AI systems. Here are a few practical applications:
Enhance Your Information Retrieval (RAG) Systems A user asks a vague question. Instead of passing it directly to your vector database and getting poor results, Arch first processes the prompt to clarify intent and extract key entities. It then transforms the prompt into a precise, structured query, ensuring your RAG system retrieves the most relevant and accurate information possible.
Build Reliable Transactional Agents You need an agent that can book appointments or process orders. Arch acts as a secure intermediary, translating a user's request like "book me a flight to Boston next Tuesday" into the correct API calls. Before execution, it applies guardrails to clarify any ambiguities (e.g., "Morning or evening flight?") and prevent unauthorized actions, ensuring the task is completed correctly and safely.
Create a Unified Interface for SaaS Tools Your teams use multiple applications like Jira, Salesforce, and Slack. With Arch, you can build a single conversational interface where a user can say, "Create a ticket for the login bug and notify the #eng-support channel." Arch intelligently detects the intent, routes the first part of the request to the Jira API, and the second part to the Slack API, orchestrating the entire workflow seamlessly.
Unique Advantages
Built on a Proven Foundation: Arch is developed by contributors to the widely adopted Envoy Proxy. It inherits the same core principles of high performance, security, and extensibility that have made Envoy the industry standard for cloud-native networking, giving you confidence that your AI infrastructure is built on a rock-solid foundation.
Framework-Agnostic by Design: Arch is not another restrictive framework. It’s a modular, interoperable gateway that works with your existing stack. This approach provides you with maximum flexibility and control, allowing you to build your agentic applications your way, without being locked into a proprietary ecosystem.
Conclusion:
Arch provides the critical, intelligent infrastructure needed to build, secure, and scale next-generation AI agents. By handling the complex, undifferentiated heavy lifting of prompt processing, security, and observability, Arch frees you to innovate and deliver real value to your users with confidence.
