Cloud computersfor AI agents.
Persistent, isolated workspaces that pause, resume, and fork with your agents.
A full computer.
A longer memory.
A workspace keeps the work, the tools, and the context around them. Your agent can leave a task and return to the same place.

One versioned template. Private copies for each project.
A workspace for every customer.
Open one by key, per customer or per project. It keeps its files and installed packages between sessions, pauses when idle and wakes on the next request.
Wakes mid‑task
in under a second.
Workspaces run on demand. When your agent calls a tool, its workspace resumes where it left off, runs the command, and pauses again when the agent goes quiet. You pay only while it runs.

Your agent.
Its computer.
Keep your model calls and agent logic. Give the agent a workspace and the tools to use it.

Monthly plans for individual builders and growing products. Every account starts on Free. Only running workspaces count toward workspaces at once: suspended ones wait in retained storage, sized for one workspace per customer. The storage counts assume 2 GiB each and are an estimate, not a limit on how many you create. Incoming data is included. Overage is off until you turn it on, with a spend cap you set. It costs $0.08 per awake hour of a 2 GiB workspace.
