AgentSky Review (2026): Pricing, Features & Honest Verdict

What is AgentSky?

AgentSky runs your AI agent on someone else’s computer and keeps it alive. You pick a harness (Claude Code, Codex, Hermes or OpenClaw), pick a model, pick which tools it can touch, and press launch. What you get back is a persistent worker with its own memory, its own sandbox, and its own address on WhatsApp, iMessage, Telegram, Slack, Discord, the web, the A2A protocol and a CLI. Close your laptop and it keeps working. Message it from your phone three days later and it remembers the thread. It launched on 3 August 2026 and finished first on Product Hunt with 247 upvotes.

The product came out of a real operational headache rather than a whiteboard. AgentSky says it has already carried more than 10,000 agent sessions for Tycoon and Webjourney, and the design decisions read like someone who has been paged at 2am by a dead agent. Everything the company argues against is a thing people are actually doing right now: an OpenClaw instance on a Mac mini in a cupboard, a bot on a Hetzner box, a Raspberry Pi under a desk. Those setups work for a weekend. By month two you are the ops team for a hobby project, and the agent has forgotten everything it learned because the process restarted and the context window is not storage.

What makes this more than hosting is the refusal to lock you in. The harness is free and swappable mid-run. The model is swappable without losing history. Your agent does not become a hostage to whichever model was best the week you set it up, which in a market where the frontier moves every six weeks is a real feature and not a marketing line.

What are AgentSky’s key features?

Any harness, any model, swapped without losing the thread

AgentSky supports four harnesses and eleven models at the time of writing, spanning Claude Fable 5, Claude Opus 5, Claude Sonnet 4.6, GPT-5.6 Sol, Terra and Luna, Gemini 3.5 Flash, DeepSeek V4 Pro and Flash, GLM-5.2 and Kimi K3. The important part is not the length of that list, it is that you can change your mind. Start an agent on Sonnet because it is cheap, move it to Opus when the work gets hard, and the agent keeps its instructions, files and conversation history through the swap. Most platforms make the model a setup-time decision you live with. Here it is a runtime one.

Eight channels, one shared memory

The same agent answers on WhatsApp, iMessage, Telegram, Slack, Discord, web chat, the A2A protocol and the CLI, and it is the same agent in each place. History, tools and state follow it. This sounds mundane until you compare it to the alternatives, where channels are something you build yourself. Slack support is the one worth calling out specifically, because it is the channel most teams actually work in and it is missing from the cheaper competitor AgentSky benchmarks itself against.

Durable runtime with snapshots and recovery

Every agent runs as a managed worker with a full timeline, automatic snapshots, backups and restore. When something faults, the agent comes back without losing the thread. AgentSky describes the history as infinitely long and continuous, which is the marketing framing, but the underlying claim is the correct one: instructions, files and decisions survive restarts. Sandboxes are isolated and boot in seconds with only the tools you attach, so an agent with email access does not implicitly have shell access to everything else.

Cloning a local agent into the cloud

Run sky clone against an agent you already have running locally and it moves to the cloud with the same instructions, model and MCP servers, keeping secrets on your machine. This is the smartest thing in the product. The hardest part of adopting hosted infrastructure is not the hosting, it is that you have three months of accumulated CLAUDE.md context and tool wiring on your laptop and starting over is a tax nobody wants to pay. Removing that tax is how you actually win a migration.

The built-in tooling matters too: more than 2,000 pre-integrated capabilities covering web scraping via Exa, image and video generation, Gmail, CRM, Notion, Slack and transcription, with no separate API keys to configure. A self-evolving mode, where the agent distills what it learns into a sharper version of itself, is listed as coming soon. Treat that one as a roadmap item, not a reason to buy.

How much does AgentSky cost?

AgentSky has no subscription and no seats. You buy prepaid credits and spend them on two meters. The harness itself is free. Model usage is billed per turn at each vendor’s public list price, so Claude Sonnet 4.6 costs $3 per million input tokens and $15 per million output, and DeepSeek V4 Flash costs $0.14 and $0.28. Compute is billed per second while the machine is awake: $0.021 per hour on 1GB, $0.038 on 2GB and $0.071 on the 4GB default. Suspended and parked agents cost nothing at all, forever. Signing up grants a $3 credit with no card required.

Now the part the marketing does not lead with. The homepage says “Starts at $3/mo”. AgentSky’s own cost estimator, set to a fairly ordinary workload of 20 turns a day with two hours awake on Claude Fable 5, returns $82.25 a month, of which $78 is model usage and $4.25 is compute. Both numbers are true and they describe different things, but a founder reading “from $3” and budgeting accordingly is going to have a bad conversation with their finance person. The honest framing is that AgentSky’s own charge is small and your model bill is the whole cost. Run a cheap model and the always-on ceiling for a 4GB machine is $51.01 a month. Run a frontier model at volume and you will pass that before lunch.

For comparison, AgentSky’s published comparison page puts Anthropic’s Claude Managed Agents at tokens plus $0.08 per session hour in beta, OpenRouter Spawn at a free CLI where you pay your own cloud and tokens, and OpenClaw Launch at $3 to $6 a month on Lite and $20 on Pro. Those are AgentSky’s figures for its rivals, so weigh them accordingly, but the shape is right: AgentSky is not the cheapest option in the category and is not trying to be.

Who is AgentSky best for?

Use AgentSky if you already have an agent running locally that you keep having to restart. That is the exact pain this solves, and the clone command means adopting it costs you an afternoon rather than a rebuild. It is also a good fit if you want your agent reachable in Slack and on WhatsApp without writing two integrations, or if you are evaluating harnesses and models against each other and want to swap them without tearing down the environment each time.

Use it if the alternative is a Mac mini in a cupboard. The monthly compute cost is genuinely low, the durability story is real, and you stop being the on-call engineer for your own side project.

Skip AgentSky if you are a Claude-only shop with engineering time to spare, because Anthropic’s own managed agents are a tighter integration and you will not use the model flexibility you are paying for. Skip it if your agent does one scheduled job a day, since a cron task on a box you already own is cheaper and simpler. Skip it if unpredictable monthly bills are a problem for you, because usage-based pricing on top of frontier model tokens is the least forecastable cost structure there is, and there is no spend cap advertised on the pricing page.

Best AgentSky alternatives

Claude Managed Agents is the tightest option if you have committed to Anthropic. You get the best harness wrapped around the best model, at the cost of wiring an API key, a beta header and an SDK yourself, and building any channel you want. It is an engineering toolkit rather than a product, and AgentSky lists it at tokens plus $0.08 per session hour while in beta.

OpenRouter Spawn goes the other direction: model-agnostic across hundreds of models, your keys, your cloud, no lock-in of any kind. The CLI is free and you pay for compute and tokens directly. Choose this if owning your infrastructure is a requirement rather than a chore, and if you have someone whose job includes keeping it up.

OpenClaw Launch is the cheap and cheerful one, with a visual configurator that ships an agent in about thirty seconds and real multi-level memory, from roughly $3 a month. The ceiling arrives fast though: one framework family, four chat apps, and no Slack. If you live in Discord or Telegram and never need more, it is the better value.

Final verdict: Is AgentSky worth it?

Yes, if you have already felt the problem. AgentSky is a well-built piece of infrastructure that solves a specific and increasingly common pain, and it solves it with more care than the category average. The clone command, the mid-run model swapping and the eight-channel reach are all real engineering rather than a wrapper around a container. Parking agents for free is a thoughtful default that most usage-based products would never ship, because it costs them money when you are not using the product.

The mark against it is the pricing presentation, not the pricing itself. The meters are fair, itemised and honestly documented on the pricing page. But a homepage that says “starts at $3/mo” next to an estimator returning $82.25 for a modest workload is going to burn trust with exactly the developer audience this product needs, and that audience checks. Go in expecting your model bill to be the entire cost, use the estimator before you commit, and spend the free $3 credit on a real workload rather than a hello world. If AgentSky fixed the headline number and shipped a hard spend cap, this would be an eight.
