What is AgentSky?
AgentSky is a platform that lets you run a range of AI agents, such as Claude Code, Codex, Hermes and OpenCode, either in your browser or through a single API. The agents are listed in a market where you can try one or compare several side by side, with no installation needed. Each agent runs on a cloud machine that is billed per second while awake and suspends when idle.
You pay for two things: cloud compute time while an agent works, and the models and tools it calls, priced at or below the maker's own rate. The agent software itself is free, and you can connect an existing Claude Pro/Max or ChatGPT Plus/Pro plan to cover model usage. You can use agents for coding, file work, research, marketing audits, job applications and similar tasks, and the pricing page includes an estimator for monthly cost.
