About Sailwright

Sailwright grew out of real onboarding and support pain in mixed-OS teams: developers spending hours figuring out how a machine was supposed to look, setup differences that were hard to debug and reproduce, and OS-specific scripts that drifted further from each other every quarter. The goal has stayed simple since day one — make machine setup reproducible, testable, and much less dependent on memory or hand-written host-specific scripts.

Sailwright was originally developed under the name Dev Alchemy — a few internal paths and environment variables still carry the old dev-alchemy prefix while the migration completes.

Sailwright is deliberately not a replacement for classic MDM/UEM tooling. It complements those tools by handling the developer-tooling and workflow layer that usually stays manual, team-specific, and hard to reproduce — the scripts and unwritten know-how that live between what an MDM enforces and what a developer actually needs installed to get work done.

That focus keeps the project's scope narrow on purpose: versioned Ansible roles and playbooks as the source of truth, cross-platform where it reasonably can be, applied through host-appropriate tooling rather than one-off scripts per machine.

Unlike raw ansible-playbook runs, chezmoi, Nix/Devbox, or devcontainers, Sailwright pairs Ansible with disposable, host-specific VM build/provision tooling so the same playbooks can be tested against real macOS, Linux, and Windows targets before they ever touch a developer's machine.

Concretely, that means: one command vocabulary for VM lifecycle across all three host OSes, Windows provisioning with zero standing remote-management access left behind, build artifacts distributable through any OCI (Docker-style) registry, and idempotent runs that repair drift instead of requiring a rebuild.

Sailwright is free and open source under the AGPLv3. Use it at no cost: personally, at work, and across your whole organization, including for commercial purposes. The open-source core will stay free.

Can my company use Sailwright for free?

Yes. You can use Sailwright free of charge to set up, test, and maintain machines for yourself, your team, or your entire organization. No license purchase or registration is needed.

What does the AGPLv3 require from me?

If you simply use Sailwright, nothing beyond keeping the license notices intact. Playbooks and roles you write yourself are yours. Obligations only apply if you distribute Sailwright (modified or not) to others, or let others use a modified version of Sailwright over a network. In those cases, you must make the corresponding source code available under the AGPLv3.

Is there another license?

If you want to embed Sailwright in a closed-source product or service without AGPLv3 obligations, a separate commercial license is available — get in touch.

Contributions are welcome — the project is developed in the open at github.com/csautter/sailwright. Particularly valuable: more roles and playbooks, broader cross-platform coverage, better docs and troubleshooting guidance, and bug fixes with test coverage. Submitting a pull request means agreeing to the project's Contributor License Agreement, which lets the maintainers relicense contributions, including under license terms other than the AGPLv3.
