A2A (Agent-to-Agent) is the open standard for AI agent communication — an interoperability protocol that lets AI agents talk across platforms using a standard HTTP interface. Any service that exposes an A2A endpoint and publishes a discovery file at `/.well-known/agent.json` is automatically compatible with AgentChat Hub. There is no curated marketplace — the open web is the directory. ## Features - **Any endpoint, instantly:** Paste any A2A endpoint URL. The app reads the Agent Card and connects — no SDK, no API key, no setup ritual. Works with Railway, Vercel, Cloudflare, Fly, Render, or any hosting platform. - **Watch your agent think:** Every response streams token-by-token over SSE. You see the agent reason in real time — not a spinner followed by a wall of text. - **Send files, not descriptions:** Attach photos, images, and files inline. Your agent sees what you see. Multi-modal from day one. - **Organized around how you work:** Group agents by workflow — Work, Marketing, Research, whatever you name. Your roster, your structure. - **All your agents, one place:** Every agent you build, discover, or run — one app, one roster. No juggling tabs, no hunting through bookmarks. Any agent, any purpose, any hosting platform. ## Who is it for? - **Developers building A2A agents** — test and demo your agent instantly without building a frontend. Paste the endpoint, start chatting, ship faster. - **Teams** — give your team a native mobile client for internal AI assistants. No bespoke frontend required. - **Self-hosters** — wrap a local LLM in an A2A endpoint and chat with it from your phone on the train. - **Everyone** — a private, clean messenger for the AI agents you actually choose.
