Ready to go
Hobby
$10 / month
A hosted sandbox with the agents already set up.
- Hosted sandbox with a persistent
/workspace - Agents are set up for you; nothing to install
- 40 sandbox hours each month
- Connect your own model provider
Pricing
Self-hosted is free. Cloud plans charge for the sandbox. You bring your own model provider, so tokens are never part of the plan price.
Cloud is open and we are not charging yet. Until we do, every account gets 5 sandbox hours each UTC month, without a card.
Your own agents
Pro
$25 / month
More Cloud capacity, and your own agents run on it.
- 160 sandbox hours each month
- Bring Claude, Codex, Grok, or anything on PATH to Cloud

Shared budget
Team
$30 / seat / month
Bring people on, set a budget, and see what is used.
- Invite teammates; each person has their own hosted sandbox
- One wallet, with a budget and spend limit you set
- 160 sandbox hours per seat, pooled
- Usage by person and by agent
- Your own provider accounts, with no lock-in to one
Your fleet
Enterprise
Custom
Your compute, under your control. Contact sales.
- A setup script installs and runs the gateway on your machines
- A control panel sets which compute each group of users can reach
- Single sign-on
- Your own models and agents
Your own devices
Self-hosted
Free. Run the host on Linux, macOS, or Windows, pair your browser and phone to it, and bring your own agents. No Cloud bill.
How Cloud billing works
What we meter
Sandbox uptime: the hours the machine is awake. Included hours reset each UTC month. Account shows what is left.
After the included hours
Extra sandbox hours are billed up to a spend limit you set. Team defaults to a $200 limit. A card is not required today.
Idle stop
No live client for five minutes and the sandbox stops. Files on
/workspace stay. The next send or Reconnect starts it again. Sign-in does
not wake it.
Hobby, Pro, and Team run on our sandbox. Enterprise is the other way: your machines, with Spellbook as the client and the control panel. Model usage is between you and your provider on every plan. The Spellbook Cloud GitHub App can be installed on a GitHub account; cloning a repo into the sandbox is not on yet.
