Upstash Box
A cloud-based, on-demand lightweight sandbox computing environment introduced by Upstash, designed specifically for hosting AI coding agents. It supports features including disk snapshots, network firewalls, file system isolation, and remote code execution.
Timeline (last 90 days)
Upstash Box is a lightweight cloud computer that starts on demand, with each box pre-installed with an independent file system, bash, git, node, and agent execution environments such as Claude Code and Codex.
Calling Upstash Box's create endpoint yields an online Linux machine in approximately two and a half seconds.
By installing dependencies once on a base box and then taking a disk snapshot, the disk state can be frozen into a reusable image, so that machines launched in parallel afterward already have all dependencies in place when they start.
In this solution, each Agent runs on a separate VPS (the author uses Upstash's Box), each allocated its own hardware resources, such as 2 CPUs and 4 GB of memory.
The Upstash free tier has a maximum limit of 10 Boxes.
The Snapshot mechanism can freeze the current state of a virtual machine into a reusable template, and Boxes created from that snapshot automatically inherit pre-installed tools and skills.
