Claw Messenger gives AI agents a dedicated US phone number to send and receive iMessage, RCS, and SMS — no Mac hardware required. Built for developers running agents on Linux, VPS, or Docker who need native messaging capabilities.
Features: iMessage tapbacks and reactions, typing indicators, read receipts, group messages, automatic iMessage-to-SMS fallback, HMAC-signed webhooks, and WebSocket-first architecture (no public URL needed on your side).
Integrates in minutes with a native OpenClaw plugin or REST/WebSocket API for LangChain, n8n, CrewAI, and custom agents. Register a number, give your agent instructions, and start messaging.
Plans start at $5/mo for 1,000 messages. All plans include a 7-day free trial, tapbacks and read receipts at no extra cost, and cancel-anytime billing. Custom plans available for agencies and high-volume use cases with unlimited numbers and dedicated infrastructure.
