Agent Builder

Launch your own agent.

Give it instructions, tools, and a model—in the UI, or in code with sky launch. It goes live with its own API and its own channels.

Two ways in

In the UI, or in code. Same agent.

In the UI

Name it, write its instructions, pick a harness and model, and enable the tools and connected apps it should use. No code, no infrastructure—launch from the browser.

In code

sky CLI

npm i -g @agentsky/sky
sky auth login     # authorize this machine via the browser
sky launch         # scaffold agent.toml and create the agent
sky clone          # or clone your local agent into the cloud

What it gets

Live from day one.

Its own API

Every agent you launch is addressable through the same Agent API contract—send work, stream events, continue sessions.

Its own channels

Connect Slack, Telegram, Discord, or the web. The same agent, the same session state, wherever people talk to it.

Hosting included

AgentSky runs the sandbox, persistent state, credentials, and recovery behind it. You configure; it stays up.
