An opinionated project generator for TypeScript, C# and F#.
Pick a template, toggle the options you want, and download a ready-to-run project as a ZIP file, right in your browser.
- Nothing to install. Everything runs in the browser, and the project is generated on the client.
- Opinionated defaults. Formatting, linting, editor settings and
.gitignorecome preconfigured, so you can start writing code right away. - Only what you ask for. Each option adds just the files, dependencies and config it needs.
