AgentSky is a managed agent-as-a-service platform for launching long-lived, always-on AI agents in the cloud with no Mac mini, setup, or infrastructure to manage. Users can choose an agent harness such as Claude Code, Codex, Hermes, or OpenClaw, pair it with a supported model, add capabilities, and launch in one click. Agents can be reached through WhatsApp, iMessage, Telegram, Slack, Discord, web chat, the A2A protocol, and the CLI, with the same history, tools, and state following them across channels. Local Claude Code, Codex, or OpenClaw setups can be cloned to the cloud while preserving instructions, model configuration, and MCP servers without copying secrets, API keys, or session history. Every agent runs as a managed worker with durable state, continuous history, snapshots, backups, restore, and an isolated sandbox that boots with only the attached tools.
