Aider still wins for a simple reason: you stay in the terminal, it respects git, and it works with almost any model. The downside is the same as every shell agent — it runs real commands on real files. Don’t give that free rein on your daily driver. Run Aider on its own Firecracker microVM, keep your keys in the box, and pair from the in-browser terminal.
What Aider is
Aider is the classic open-source AI pair programmer for the terminal. Drop into a git repo, point it at Claude, GPT, Gemini, DeepSeek, or a local model, and it reads relevant files, proposes edits, and commits as it goes. Model-agnostic and BYO API key — the community still treats it as one of the most-used coding CLIs for a reason.
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 Aider
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 Aider 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 Aider in 3 steps
1. Pick a plan and pay
Starter is enough for most Aider work. Checkout runs the auto-provision chain — no manual SSH to stand the box up.
2. Your microVM boots with Aider ready
A fresh Ubuntu microVM boots with the CLI pre-installed and on your PATH. Open the in-browser terminal:
export OPENAI_API_KEY=… (or ANTHROPIC_API_KEY / your provider), cd into a repo, then `aider`
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 Aider 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.
