The Bottom Line
- Best for
- Teams that want Claude Code or Codex as a cloud API and can park agents when they are idle
- Price
- Free plan available, paid tiers above. Compare plans
Key facts
- One API to run Claude Code, Codex, Hermes, OpenClaw, and others on a cloud machine
- Prepaid credits: tokens at published /1M rates plus compute per second (default at a set hourly rate)
- Connect a paid subscription for advanced models and model usage is $0; parked agents cost $0 compute
Pros
- No seat fee and no card to start; you prepay usage
- Parked or idle agents do not burn compute
- Can point eligible agents at a paid subscription for advanced models you already pay
Cons
- Two meters (tokens + compute) plus per-action tool prices make a session total hard to predict
- Card top-ups add a small fee on top of credits
- Always-on default machine is costly if you never let it sleep
What is AgentSky?
AgentSky is a cloud agent API at agentsky.dev. You pick a harness (Claude Code, Codex, Hermes, OpenClaw, pi, DeepSeek Harness, Kimi Code, opencode) and a model; AgentSky runs a persistent machine so the agent keeps state between turns. Billing is prepaid credits on two meters: model tokens at the published per-1M rates, and compute per second while the machine is awake (default 2 vCPU / 4 GB at a set hourly rate). Idle or parked agents are $0 compute. Connect a paid subscription for advanced models and eligible agents bill $0 model usage on AgentSky (compute still meters). Sign-up needs no card. Stripe takes a small fee on card top-ups.

Is AgentSky worth the price?
Good value
The sticker is $0 to sign up.
Real spend is tokens plus $0.075/hour on the default box, plus tool calls. Bring Claude or ChatGPT and the token line can drop to $0, which is the main way to keep the bill small.
Predictable only if you park agents when you are done.
Hidden Costs & Gotchas
Stripe 2.9% + $0.30 on every card top-up.
Compute still meters even when model tokens are $0 via your Claude/ChatGPT plan.
Browser, image, and video tools are extra per action and can dominate a session.

AgentSky FAQ
How does AgentSky handle persistent state for agent workflows?
AgentSky runs a persistent cloud machine that keeps state between turns, so the agent maintains context across multiple interactions. You pick a harness and a model, and the machine stays alive until you park or idle it, preserving the agent's memory.
How does AgentSky compare to E2B for cloud-based agent execution?
AgentSky differs from E2B in that it charges no seat fee and requires no credit card to start; you prepay usage credits that cover both model tokens and compute time. Idle or parked agents incur no compute cost, which may reduce costs for intermittent workflows.
Why is it hard to predict the total cost of a session on AgentSky?
The total cost of a session on AgentSky is hard to predict because billing uses two separate meters (model tokens and compute time) plus per-action tool prices, making the final amount variable. Additionally, card top-ups incur a small fee on top of credits, and the default always-on machine can be costly if not allowed to sleep.
Which teams benefit most from AgentSky's persistent agent architecture?
Teams that build long-running agent workflows requiring state between turns benefit most from AgentSky's persistent machine architecture. Developers using agent harnesses like Claude Code or Codex can run agents that maintain context across multiple interactions without paying for idle time.
How is AgentSky priced?
AgentSky is priced with a free tier available, and paid plans for more usage and features. Billing is prepaid credits on two meters: model tokens at published per-1M rates and compute per second while the machine is awake. Idle or parked agents incur no compute cost.
Can AgentSky integrate with a paid subscription for leading models?
Yes, AgentSky allows you to connect a paid subscription for leading models, and eligible agents then bill $0 model usage on AgentSky (compute still meters). This lets users leverage existing model subscriptions without double-paying for tokens.
Does AgentSky support multiple agent harnesses?
AgentSky supports a range of agent harnesses including Claude Code, Codex, Hermes, OpenClaw, pi, DeepSeek Harness, Kimi Code, and opencode. You pick the harness and a model, and AgentSky runs the agent on a persistent cloud machine.
When would an agent's compute cost be zero on AgentSky?
An agent's compute cost is zero when the machine is idle or parked. While the machine is awake, compute meters per second; but if you let the agent sleep or park it, you pay $0 compute until it resumes.
