Celesto Sandboxes / Compare

Celesto vs Google Cloud

Celesto vs Google Cloud Agent Platform Sandboxes: Celesto gives each agent a virtual machine with root, an interactive shell, a desktop, and a CDP browser for 83% less per hour on the same CPU and memory, while Google's container sandboxes run one command per request without sudo, add a monthly free tier, and fit teams already inside Google Cloud.

Pick by where the agent lives: an agent that needs a full machine and a lower hourly price favors Celesto; an agent built on Gemini Enterprise Agent Platform, with VPC controls and Google billing, favors Google's sandboxes.

Google prices are its Agent Platform Sandbox rates per hour; sandboxes are billed while they exist, and paused ones at an unpublished lower rate. Code Execution sandboxes come in two fixed sizes. Celesto prices include the root disk and apply while the sandbox runs.

Agents that need a full machine run cheaper on Celesto.

Choose Celesto if

  • You want to pay 83% less per hour for the same CPU and memory
  • Your agent needs root, an interactive shell, and Docker
  • Sandboxes should start in seconds every time, not after up to 2 minutes cold
  • You want TypeScript, a CLI, or an MCP client to drive sandboxes

Choose Google Cloud if

  • Your agents already run on Gemini Enterprise Agent Platform
  • Your security model depends on VPC Service Controls and your own VPC egress
  • Your usage fits inside 50 vCPU-hours and 100 GiB-hours a month
  • You want to run sandboxes on your own GKE cluster with Agent Sandbox

Questions.

What does Google Cloud offer for AI agent sandboxes?

Google Cloud's managed option is Agent Platform Sandboxes in Gemini Enterprise Agent Platform: Code Execution, Computer Use, Shell, and custom containers. It also offers GKE Agent Sandbox, an open-source gVisor-based project you run on your own GKE cluster, and Cloud Run sandboxes in Preview.

Is Celesto cheaper than Google Cloud Agent Platform Sandboxes?

Yes, on list price. Google charges $0.085 per vCPU-hour and $0.009 per GiB-hour while a sandbox exists, $0.206 an hour for 2 vCPU and 4 GiB. Celesto Standard has the same CPU and memory for $0.030 an hour with a 30 GB disk, at least 83% less on every matched size. Google includes 50 vCPU-hours and 100 GiB-hours free each month.

Can I get a shell and root access in Google's sandboxes?

Google's Shell sandbox runs one command per request, each in a new shell, as a user with no sudo. A Celesto sandbox is a full Linux machine with sudo, an interactive shell through celesto computer ssh, and a terminal in the browser console.

What is a good Google Cloud alternative for AI agent sandboxes?

Celesto works with any agent framework, inside or outside Google Cloud: each sandbox is its own virtual machine with root, a terminal, desktop view, CDP browser, public preview URLs, Docker, and a disk that survives stops, from $0.015 per hour. New accounts get a one-time $5 credit with no card.

Start with $5 in credits. No card required.
