Cognition's Devin for Terminal puts the agent in your shell: install with one curl, log in, work the repo, optionally hand off to the cloud. The failure mode is still the same as every tool-using agent — if it only lives on a laptop, you stop using it; if it shares a kernel with neighbors, isolation is theater.
Here's the clean setup: run Devin on its own always-on Firecracker microVM.
What Devin for Terminal is
Official install:
curl -fsSL https://cli.devin.ai/install.sh | bash
That lands devin on ~/.local/bin (versioned under ~/.local/share/devin/cli/_versions/).
Useful entry points:
devin— interactive sessiondevin auth login --force-manual-token-flow— remote/SSH-safe authdevin -p "…"— non-interactive print modedevin models,devin mcp,devin skills,devin pluginsdevin cloud— cloud resources when you need handoff
User config: ~/.config/devin/config.json. Credentials: separate (credentials.toml after login). Skills under ~/.config/devin/skills/.
Why a real microVM
Devin acts on a real filesystem and can call tools. Laptop blast radius = everything you can reach. Shared containers still share a kernel.
jurniti gives Devin its own Firecracker microVM — own kernel, KVM boundary, one tenant per box.
You keep Cognition auth. Login stays in the guest. We run the box; we don't own your agent relationship.
Most CLI work fits Starter (1 vCPU / 2 GiB). 30-day money-back.
Run it in 3 steps
1. Pick a plan and pay
Starter is the default. Checkout auto-provisions.
2. Boot with Devin ready
devin auth login --force-manual-token-flow
devin auth status
cd your-project
devin
3. Put it to work
Add AGENTS.md, install skills, wire MCP, use -p for unattended jobs. Config survives restarts on the persistent home.
What people run it for
- Terminal-native Devin without babysitting a desktop session
- PTY-safe auth on remote boxes
- Headless jobs with
devin -p - Skills + MCP with secrets that never leave the guest
- Cloud handoff when a job outgrows local compute
Snapshot into a template — skills and config structure, never credentials.
