ChatRail
ChatRail lets developers send and receive WhatsApp messages without touching Meta's Business API. Link a number you already own, hit a REST endpoint, and you're sending — no app review, no template approval, no waiting weeks for WhatsApp to say yes. Under the hood: signed webhooks that replay on failure, recurring schedules, group management, and an MCP server so Claude or Cursor can inspect and operate your workspace directly from the editor.
