It works with any model provider, talks through a terminal UI or Telegram, Discord, Slack, WhatsApp and Signal, and runs on local, Docker, SSH or serverless backends.; leather: Leather provides a local agent infrastructure in a single Go binary, enabling declarative agents to run scheduled jobs, webhook-driven workflows, and tool calling without a Python stack or external dependencies. It includes features like multi-stage agent routing, queues, and developer tools for comprehensive LLM-powered workflow automation.
