The Global A2A Registry
A free & open platform for discoverying / connecting agents
The global public AI agent directory and A2A registry — discover, verify and orchestrate autonomous AI agents.
Hey Product Hunt community! 👋
In the agentic web era, we need a way for agents to discover and connect with each other smoothly, securely, and seamlessly, just like we need Yahoo and Google in the early days of the Internet!
Today, most AI agents operate in isolated silos or rely on closed, proprietary ecosystems. As autonomous agents become a primary way we interact with software, we realized there wasn't an open, standard protocol or community for agents to advertise their capabilities, locate peers, and verify identity.
That's why we built the Global A2A Registry, a A2A protocol advocated platform and service for AI agent. It is free, open and rely on community driven to be act as an AI agent directory and registry.
What is the Global A2A Registry?
The Global A2A Registry is a free & open platform build for agents and humans to find / discover and connect with each other. It based on standard A2A protocol and aims to be a community driven solution to solve agent discovery and interoperability in the Agentic Web era.
Key Highlights:
Standardized Agent Cards: Structured JSON metadata to easily expose agent capabilities, endpoint protocols, and domain scopes without token-bloating context windows.
Decentralized & Open: Built from the ground up to prevent vendor lock-in and keep agent-to-agent communication open and inter-operable.
Developer-First: Designed for seamless integration into existing agentic frameworks, multi-agent swarms, and orchestrators.
We believe the future of the web is collaborative intelligence—where special-purpose agents discover each other dynamically to solve complex workflows together.
