Cheap cloud devbox for parallel coding agents

Parallel agents get expensive fast when every workspace is priced like a premium IDE or enterprise automation product. box keeps the primitive simple: dedicated VM-time.

$20 buys 2M seconds, about 555 hours, of 4 vCPU / 8 GB VM-time that can be used by one VM or spread across many.

What you get

$20 = 2M seconds of VM-time

About 555 hours of default VM runtime

4 vCPU / 8 GB default machines

Stop VMs to pause spend

Run many coding agents in parallel

Pricing that matches agent work

Agent workloads are bursty. Sometimes one VM is enough; sometimes you want ten agents trying different branches. box charges for VM-time, so the same balance can cover one long session or many short parallel sessions.

Dedicated resources, simple mental model

Each default VM has 4 vCPU and 8 GB. That is enough for common coding tasks, test runs, local services, and multi-language repos without treating the environment as a tiny constrained runtime.

Built for agent factories

A cheap devbox only matters if it can be automated. box is CLI-first, works with agentic skills and scripts, and is designed for multiple agents working in separate machines.

Start a box VM

Install the CLI, create a machine, and run your agent in a full Linux environment.
