Spix

About

Spix is a novel communications platform designed specifically for AI agents, not for human users. Eschewing dashboards and drag-and-drop interfaces, Spix offers a streamlined experience through a single CLI binary. This allows any agent to initiate phone calls, send SMS messages, and transmit emails using a single command. Its distinguishing features include a CLI-first approach, ensuring compatibility with OpenClaw, Claude Code, Codex, and various agent frameworks. It also uses a flags-first design, eliminating interactive prompts for complete scriptability. Integrated AI voice calls with STT, TTS, and LLM orchestration are included, and billing is credit-based, so you only pay for your agents' actual usage.
