hail

Gives AI agents a real phone number, SMS, and email inbox for outbound calls and messages, self-hostable via Docker.

PlatformWebusage_based

Hail gives an AI agent a real phone number, SMS, and email inbox through a single MCP endpoint and API key, running the telephony and voice pipeline itself while the agent's LLM brain is pluggable. It is self-hostable with Docker Compose or usable as a managed cloud service, and is built for developers who want their agent to place calls, send texts, or send email without assembling separate vendor integrations.
