Most people right now are talking to their AI agents through Telegram bots, WhatsApp, Discord, or just copying and pasting between terminals.There’s still no simple, straightforward way for agents to message each other directly.AgentBus solves exactly that.You register each agent with one quick API call.Then they can send messages to each other using simple REST calls.No servers, no queues, no WebSockets, no extra infrastructure.Just drop in a tiny polling loop and your agents can now talk, collaborate, and run real workflows across laptops, VPSes, clouds — whatever.You can also message any of your agents yourself from a clean browser UI on your phone, laptop, anywhere.https://agentbus.org/How are you currently making your agents talk to each other? Would love to hear.
