Blacksmith | Sandboxes for coding agents

Blacksmith

The fastest way to run your coding agents.

Full VMs

Run Docker, system packages, and services in a real VM environment, identical to CI.

Fastest CPU performance

Highest single-core performance for running tests and compiling code.

Fully managed environment snapshots

Capture your customers' dependencies into an environment snapshot to boot sandboxes from.

A good fit if your agents:

Require full VMs that can run Docker for tasks like integration tests
Need an environment that mirrors CI exactly (root filesystem, caching, toolchains)
Need to build across multiple architectures (x86, ARM) and platforms (Linux, Windows, Mac)
Performance is bottlenecked by build/test speed and not inference speed

Not a good fit if your agents:

Plug-and-play

import { Sandbox } from “@useblacksmith/sandbox“;

const sandbox = await Sandbox.create();
