Agent servers Live

A cloud machine for you and your coding agents

Each agent server is its own Kata VM with Ubuntu, Docker, your toolchains and coding agents preinstalled. Connect over SSH from VS Code, Cursor or Zed, or open the web terminal in the portal. Billed by the hour from $12 a month; stop it and compute billing stops.

How it works

Agent servers, step by step

  1. Step 01

    Add your SSH key

    Register a public key on your account once; the bastion authenticates every connection with it.

  2. Step 02

    Create a server

    Pick a size (w1, w2, w3) and a region. It is ready in about a minute.

  3. Step 03

    Connect

    ssh -p 2222 <server-id>@ssh.us-east.databasezy.com, zb ws code for VS Code, Cursor or Zed, or the web terminal.

  4. Step 04

    Stop when you are done

    Stop it yourself or let it stop after an idle period. The disk is kept; compute billing stops.

What you get

  • A VM per server

    Every server runs in its own Kata VM in its own namespace, with Docker inside it and no access to other customers' networks.

    Live

  • SSH through a bastion

    Key-only SSH on port 2222, routed by server id, with your registered keys. Every session is recorded as a security event and can be revoked.

    Live

  • Web terminal

    A terminal in the portal for when you are away from your laptop.

    Live

  • Agents and toolchains preinstalled

    Claude Code, Codex, OpenCode and Gemini CLI, with Node, pnpm, Bun, Python, Go, Rust, Git and Docker. Bring your own agent subscriptions.

    Live

  • Stopped means no compute charge

    A stopped server pays only for its disk. Compute is metered from start and stop events, by the hour.

    Live

  • Daily snapshots

    Daily snapshots of the home volume, restore into a new server and export to a bucket.

    Coming soon

  • Your repositories

    GitHub repositories cloned under ~/dev with an installation token, and shared agent instructions from the project.

    Coming soon

  • Next to your databases

    Attach a server to a project to reach its instances inside the cell.

Try it

From key to editor in five commands.

shell
zb ssh-key add                         # registers ~/.ssh/id_ed25519.pub
zb ws create dev --size w1 --wait
zb ws ssh-config dev --write           # adds "Host zb-dev" to ~/.ssh/config
zb ws code dev --editor cursor         # or code, zed
zb ws stop dev                         # compute billing stops, disk is kept
ssh
# Plain ssh, no CLI needed: the user name is the server id
ssh -p 2222 [email protected]

Questions

What do I pay when a server is stopped?

Only its disk, at $0.125 per GB-month. Compute is billed per running hour at the size price and stops the moment the server stops.

Is it a container or a VM?

A VM: each server runs in its own Kata Containers VM, which is what lets Docker run inside it safely.

Which editors work?

Anything that speaks SSH. VS Code and Cursor with Remote-SSH, and Zed's remote projects; zb ws ssh-config writes the Host block for them and zb ws code opens the editor.

Can my teammates get into my server?

No. The bastion checks on every connection that the key belongs to the server's owner. Admins can revoke sessions and set how many servers each member may own.
