One API, any agent
Pick any agent and model. AgentSky handles the persistent computer — crashes, reconnects, and state are not your problem. Every session the API starts also opens in the browser, so a frontend is optional — use ours, or ship your own.
Tools · Connectors · Channels
Add built-in tools, connect apps, or enable channels as parameters on the agent call. Nothing separate to set up.
Agent Hosting
One command copies the agent you already run—same instructions, same model, even the same subscription. From there it's a cloud agent like any other, on the same API.
One command clones its instructions, model, and MCP servers. Same agent, now on the API—running while your laptop is closed.
Connect Claude Pro, Claude Max, or ChatGPT once. Eligible agents run at $0 model usage—no second bill for the same models.

FAQ
AgentSky runs agents in the cloud — Claude Code, Codex, Hermes, pi and more, each on the model you choose. Start them in your browser, or call them from your code behind one API; every session also opens in the browser, and persistent sessions keep state between messages. You pay per minute of agent time plus per token of model usage.
