AgentSky
AgentSky is managed agent-as-a-service: one click launches a long-horizon AI agent into an isolated cloud sandbox with durable state, full history and automatic recovery, reachable from WhatsApp, iMessage, Telegram, Slack, Discord, web, API or CLI. It removes the infrastructure work of running always-on agents without locking users to a single harness or model.

Products & Services
One-click launch of a long-running agent into a secure isolated cloud sandbox, with persistent memory, full conversation history, state snapshots and managed recovery. Harness and model can be swapped later without losing history.
Terminal-first control plane — sky launch to start an agent in two commands, sky agent chat for interactive or one-off messages, sky clone to lift a local agent into the cloud, plus session listing and management. Configuration is declarative via agent.toml.
HTTP API at https://agentsky.dev/api/v1 using a 202-send plus one standing Server-Sent Events stream, with event replay via GET, deduplication, revocable API tokens and headless/CI support through environment variables.
The same agent reachable from WhatsApp, iMessage, Telegram, Slack, Discord, the web app, the API and the CLI.
Market Position
AgentSky's pitch is neutrality: rather than being the hosted version of one harness, it runs Claude Code, Codex, Hermes and OpenClaw side by side over any model, and lets you swap either without losing the agent's history. That makes it a hedge against harness lock-in in a market where the harness layer is still churning. The other differentiator is reach — the same agent answers on WhatsApp, iMessage and Telegram, not just in a browser tab — and per-second billing with free parking, which suits agents that idle most of the day.
Key Competitors
Leadership
Founders
Xiaoyin Qu
Founder of Tycoon.us, the product AgentSky was extracted from and still powers. Previously founded Run The World (a16z-backed) and HeyBoss, where her AI-CEO experiment — stepping down in favor of an AI CEO named Astra — drew wide coverage. Stanford dropout, formerly at Meta. Listed as a maker on the AgentSky Product Hunt launch.
Founding Story
The idea came out of building Tycoon (tycoon.us), where the team hit the parts of agent infrastructure nobody budgets for: testing many harness/LLM combinations, fast and secure sandboxes, surviving restarts, and wiring one agent to every channel a user actually lives in. AgentSky was extracted as the platform underneath that work and has since handled 10,000+ agent sessions powering Tycoon in production.
Business Model
Revenue Model
Prepaid credits, no subscription and no seats. Usage is metered on two axes — model tokens per turn and sandbox compute per second while the agent is active. Idle agents auto-suspend and parked agents are free, so cost tracks actual work.
Pricing Tiers
New accounts get $3 in credit with no card required. The homepage's 'from $3/mo' framing refers to this entry-level spend, not a subscription.
Roughly $15.24/month if the agent runs continuously. Billed per second only while active.
Roughly $27.16/month if always on.
Roughly $51.01/month if always on. Default sandbox size.
Ranges from DeepSeek V4 Flash at $0.21 in / $0.42 out per 1M tokens up to Claude Fable 5 at $15.00 in / $75.00 out per 1M tokens. Billed per turn.
An agent that is not running costs nothing to keep.
Connect an existing Claude Pro/Max or ChatGPT subscription and pay no model charges on eligible agents — compute is still metered.
