OpenHands is what a lot of builders mean when they say “open coding agent” after Claude Code and Codex. It’s powerful, and that power is exactly why you don’t want it loose on the laptop you use for banking, SSH keys, and browser sessions. Here’s the fix: run OpenHands on its own always-on Firecracker microVM, give it root there, and keep the blast radius to one disposable box.
What OpenHands is
OpenHands is an open software-development agent with a large OSS community — the name many people reach for after Claude Code and Codex. The CLI/TUI mode runs in your terminal, talks to your LLM of choice, and can take headless tasks for automation. The heavy lifting is the model; what OpenHands needs is a shell, your files, and a place that stays up.
It’s happiest on a box that’s always on: hand it a refactor, a failing suite, or a multi-file cleanup and let it grind while your laptop is elsewhere.
Why a real microVM for OpenHands
A coding agent runs bash. It installs packages, edits files, and executes model-chosen commands. On your laptop, that has the run of your home directory, SSH keys, and browser sessions. Containers share the host kernel. jurniti gives OpenHands its own Firecracker microVM — own kernel, KVM hardware boundary, one tenant per box. Hand it root there; a runaway stays contained. Something goes sideways? Reprovision in seconds.
You keep your model / product relationship. jurniti’s BYOK is architectural: credentials live only in your VM, traffic goes straight to the vendor, and we never sit as a token proxy.
Most CLI agent work runs on Starter (1 vCPU / 2 GiB). Every plan has a 30-day money-back guarantee on first purchase; workspace kept 7 days after cancellation.
Run OpenHands in 3 steps
1. Pick a plan and pay
Starter is enough for most OpenHands work. Checkout runs the auto-provision chain — no manual SSH to stand the box up.
2. Your microVM boots with OpenHands ready
A fresh Ubuntu microVM boots with the CLI pre-installed and on your PATH. Open the in-browser terminal:
export LLM_API_KEY=… and LLM_MODEL=… (or follow first-run settings), then `openhands`
3. Put it to work
Point it at a repo, hand it a task, close your laptop. Config on the persistent home survives restarts. Snapshot into a template when you want to fork the setup without leaking credentials.
What people run OpenHands for
- Always-on sessions. Long refactors and test loops that outlast a commute.
- Isolation for autonomy. Give the agent a real shell without risking your primary machine.
- A pinned environment. Tools and project state set up once, always there.
- Parallel agents. Multiple microVMs instead of a tangle of local tabs.
