Pricing
Billed per second, only while a sandbox runs. A stopped sandbox costs no running time and keeps its disk. Every VM runs Ubuntu 24.04 or 26.04, Debian 13 or Omarchy with Docker, Chrome, a desktop and coding agents installed.

A plan is needed to start sandboxes. It's not a fee: every plan dollar comes back as usage in that billing period. Each plan buys one VM of the matching size running all month, or the same money spread over many short runs.

Usage past the plan comes from your wallet, a prepaid balance. Unused plan usage expires at the end of the period. Need more sandboxes at once? Email hello@froog.tech.
The first 7 days are free: 25 hours of running time, up to 2 sandboxes at once, in the small and default sizes, each with an auto-stop of 2 hours or less. One trial per card. The trial starts with your first plan. A card is needed, and nothing is charged until the trial ends.

This compares price, not speed. froog's vCPUs are shared, like everyone's here. A VM that runs only part of the month costs less, at froog and at the other per-second and hourly providers. Prices change; tell us if one of these is out of date.
Included at no cost
- Automatic snapshots of every VM, and a stopped VM's disk for 14 days
- Saved snapshots, kept until you delete them: 10 with the $10 and $20 plans, 25 with the $50 plan
- Network traffic (no egress charges), SSH from anywhere, and HTTPS URLs for any port
- The desktop in your browser, SSH, and the file and exec API
/dev/kvminside every VM, for QEMU, Firecracker or the Android emulator- Account environment: env vars, repos, secret files and a setup script in every VM
How billing works
- Running time is billed per second at its size's hourly rate, only while a sandbox runs. Stop a sandbox and its running time stops too. Its disk is kept 14 days, and a saved snapshot keeps it longer.
- Your plan is charged at the start of each billing period, and its full amount is usage you can spend in that period. Unused plan usage expires at the end of the period. It doesn't carry over.
- Plan changes apply at once. An upgrade charges the difference for the rest of the period, and that money comes back as usage too. Cancel and the plan ends at the end of the period.
- Usage past the plan comes from the wallet. Add money with
froog wallet pay 15($15 minimum), charged to your saved card. Auto top-up (froog wallet auto 20) adds that amount whenever plan usage left plus the wallet drops below 10% of it. - If plan usage and the wallet both run out, new starts fail and running sandboxes get a 24-hour grace period, then they stop (sooner if the grace period adds more new debt than 25% of the plan, or $5 on smaller plans). The grace period's usage goes on the wallet as debt. Each stop snapshots the disk, so nothing is lost. Paying into the wallet lifts it.
- Saved snapshots past those included cost $0.056 per snapshot per day, from the wallet.
- Stripe charges the plan monthly, and wallet payments are separate charges.
