AgentSky is a managed cloud service for launching and running long-horizon AI agents across multiple harnesses and models, including Claude Code, Codex, Hermes, and OpenClaw. Users can reach their agents through WhatsApp, iMessage, Telegram, Slack, the web, CLI, or an A2A protocol, with the agent's state, history, and tools persisting across channels. The platform handles durable state management, snapshots, backups, and recovery automatically, so agents can run continuously for months without losing context. Developers can interact with AgentSky entirely through a REST API or CLI, making it easy to integrate into existing workflows or products. Built-in capabilities include web scraping, image and video generation, email, CRM connectors, and access to over 2,000 additional integrations.
