Krova Cloud vs Vercel Sandbox
Ephemeral sandboxes for running AI-generated code, inside Vercel. Here is the same machine priced both ways, the arithmetic that produced each number, and what a Cube gives you beyond the price.

What you get on a Cube that you don't get there
Price is the headline. This is the part that decides whether you stay.
No maximum runtime. Their sandboxes are capped at 45 minutes on Hobby and 24 hours on Pro — a Cube runs until you stop it.
Any disk size you like. Every one of their plans caps a sandbox at 32 GB, on Hobby, Pro and Enterprise alike.
Full root SSH into a real Linux server you can also serve production traffic from, rather than an execution environment that has to hand off to something else.
Memory is billed on what you provision either way, but our vCPU is billed on the minute the machine is up rather than metered per active CPU-hour — one predictable line instead of two variable ones.
Snapshot a warm base once, then clone it into a fresh Cube per run, so every agent starts from a known-good machine.
Export any Cube as a portable .cube archive and import it again — your environment is a file you hold, not state inside one vendor's platform.
Before you decide
Where do these Vercel Sandbox numbers come from?
From Vercel Sandbox's own pricing page, opened in a browser and read off it on 2026-08-13 — not from a blog post, a comparison site or memory. The rates and the arithmetic are printed above so you can redo the sum yourself, and a build-time guard fails once any comparison on this site passes ninety days, so a stale reading cannot sit here quietly.
Why is Krova Cloud cheaper at the same size?
You pay per resource — $0.001 per vCPU-hour, $0.0025 per GB of RAM and $0.00005 per GB of disk — instead of buying a fixed plan and rounding up to whatever it includes. There is no platform fee and no subscription on top, so what you pay for is the machine you asked for, by the minute — and every GB of RAM and disk in it is reserved 1:1 against real hardware.
What am I committing to?
Nothing monthly. There is no subscription and no minimum — you top up prepaid credit and pay for the minutes a Cube runs, and powering one off stops compute billing that same minute, with only its disk still billing. Signing up is free and needs no card, and your first top-up of $5 or more earns a flat $5 bonus credit, one-time.
What exactly is a Cube?
A Firecracker microVM with its own Linux kernel and full root SSH, inside a per-cube jailer sandbox — install anything, run systemd, run Docker, and leave it up as long as you like. Your app is public; your server isn't: outbound is unrestricted, so package installs, image pulls and API calls all work normally, while nothing reaches in until you map a port, and every mapping takes an IP allowlist. Custom domains run through the managed HTTPS ingress, so the origin is never exposed.
Run the same machine for $9.93 a month
No subscription and no minimum — top up prepaid credit, size a Cube however you like, and compute billing stops the minute you power it off. Signing up is free and needs no card, and your first top-up of $5 or more earns a flat $5 bonus credit, one-time.
