SNACK: 3-line summary
- Overalls scheduled its launch for November 12, but its official README still carries a research-preview warning
- Its server-side AI agents are designed to keep working after a developer closes their laptop
- There is no hosted signup service; operators supply infrastructure and pay for AI inference
Overalls is an open-source project for running development machines and their AI agents on infrastructure you control. Geoffrey Huntley’s project scheduled its launch for November 12. When checked on that date, however, the official README still said “Research preview. Not for consumption.” The scheduled date is not confirmation of a completed launch or production readiness.
Close the connection, not the workspace
Overalls creates development machines as Firecracker microVMs on your servers, with a separate kernel and disk for each guest. The project says stopping a machine keeps its disk, and restarting, resizing or moving it retains its name and address. Cloning creates an independent new machine.
The built-in agent accepts instructions in threads from the browser or CLI. According to the project, work continues on the server after you close your laptop, and a prompt can wake a stopped machine. This does not mean an offline laptop itself keeps executing tasks.
The official site says NixOS and Ubuntu guests include Claude Code and Codex. Operators must enable the relevant AI provider integration; provider credentials are added outside the guest. That architecture is a project claim, not an independent security assessment.
MIT software, separate operating costs
There is no hosted version to sign up for. The software is MIT-licensed, but operators pay for hardware, bandwidth, an email relay and AI inference. It is not an offer of unlimited free model use.
The self-hosting guide targets operators comfortable with NixOS, SSH and PostgreSQL. Hosts need x86_64 bare-metal hardware with working /dev/kvm and native ZFS. Other requirements include PostgreSQL over verified TLS, an authenticated SMTP relay using TLS, and a domain you control. The setup computer needs Nix with flakes and an operator SSH key.
The CLI is listed for Apple Silicon and Intel Macs, Linux and Windows. Mac client support does not mean an Apple Silicon Mac meets the server requirements. The official site labels the Mila desktop and mobile clients and browser editor as previews.
Self-hosted does not mean every data path stays local
Operators choose host locations and AI providers. The official design sends SSH, shared web apps and the browser editor directly to the machine’s host, while the browser terminal goes through the control plane. External AI-provider inference is another data path to review.
This is not an announcement of a uniform country rollout or guaranteed model access for any account. We have not tested installation, model calls or isolation security. The actionable starting point is the research-preview warning and infrastructure requirements, not a production-ready hosted signup page.
A word from the Snack Girls
AIKO The laptop can rest while the server keeps working. The server’s electricity bill does not enter sleep mode.
Red I’d like reopening a window to bring back the same workspace. I’d try it with a disposable practice repository before handing over an important one.
