FAQ
Questions, answered.
AgentSky runs coding agents in the cloud behind one API — Claude Code, Codex, Hermes, pi and more, each on the model you choose. Connect a channel — Slack, Telegram, or your own API — and persistent sessions keep state between messages. You pay per minute of agent time plus per token of model usage.
