Why

• Nothing leaves your browser. All generation happens client-side in plain JavaScript — no server, no telemetry, no accounts.
• No build step. Each tool is a single self-contained HTML file. Clone the repo and open it directly, or serve it with any static file server.
• No dependencies. No framework, no bundler, no npm install.

Running locally

git clone https://github.com/linusali/hatch.git

Or just open index.html directly in a browser.

Project structure

index.html      landing page
sysprep.html    Windows sysprep / autounattend.xml generator
cloudinit.html  cloud-init user-data / network-config generator
nmstate.html    nmstate state YAML / NodeNetworkConfigurationPolicy generator

Each tool page is fully self-contained (HTML + CSS + JS in one file) — there is no shared build artifact or component library to keep in sync.

Contributing

Issues and pull requests are welcome. Since each tool is a single file, most changes are localized — no build pipeline to fight.
