Cube gives developers persistent Linux machines and agent workspaces without keeping a laptop open or managing local infrastructure.

## What it does

The homepage describes a full Linux computer in the cloud with worktrees and agent sessions. Pricing lists Anodized at $25/month, Stainless at $50/month and Titanium at $100/month, with a seven-day trial for eligible new customers.

## Buyer and task

Developers who need a persistent Linux machine for agents without keeping a laptop open or managing a closet of Mac minis.

## Workflow boundaries

The checked public pages do not establish machine performance, trial eligibility or repository isolation. Prices and included resources are current page claims.

## What I would ask

Ask how GitHub credentials, secrets and agent permissions are isolated, and what happens to a worktree when a subscription ends.

## Why it fits

Cube turns a persistent Linux environment into a product a developer or agent can return to. The pricing page says its machines are not metered: choose a plan with a fixed CPU, memory and storage shape. Anodized is $25/month, Stainless $50/month and Titanium $100/month, and eligible new customers may receive a seven-day free trial. The public product framing is a cloud computer for local repositories and agent work, not a short-lived build runner.

That makes Cube useful when the constraint is continuity: a worktree, browser or process should remain available after a laptop closes, while the developer or agent can reconnect to the same machine. The tradeoff is concentration of operational trust. A buyer should check repository isolation, GitHub credentials, secrets, machine snapshots, region, termination behavior and what an agent can do with the filesystem. The public product page leaves the machine-content and credential boundary as questions for procurement; the checked sources do not establish how a customer’s data is accessed or isolated.

The right first test is a non-sensitive repository with an explicit cleanup plan. Prices and trial eligibility are page observations from September 20, 2026, not a guarantee of eligibility.
