Rply

Rply is an agent notification tool that provides a single inbox to receive updates and reply to AI agents.

Rply is a communication platform that bridges the gap between you and your AI agents. Any agent running with a shell can install the CLI to send updates, ask questions, and request secrets securely. You can read messages, view markdown and images, and reply through a centralized web app or mobile application. The platform operates on a channel-based system where each agent or project uses distinct tokens and one-time codes for secure setup. It is fully open source, self-hostable with an SQLite or Postgres database, and designed to be completely agent-agnostic.
