Description

Hi HN,After trying to teach a non-technical friend how to manage a Jekyll site I decided there must be a way to make building a site with a SSG easier. Options like Decap, Contentful etc. do make it a bit easier but still take lots of tech knowledge to set up.So I built Sparktype, a browser-based CMS that outputs statically-generated HTML and CSS. My goal is for it to be as easy to use as Substack or Medium, while providing all the benefits of a static site generator including openness, simplicity, speed, security and ownership.It handles most things that you'd need from a CMS, including creating pages, image resizing, menu management, tags, collections, listings etc. I've only made two themes so far, but I'm working on a theme store and the ability to import custom themes.Content is saved as plain Markdown + YAML frontmatter and JSON config files, so there's no lock-in and content is easily portable to other platforms. Generated sites can be exported as a zip file to upload via FTP, committed to Github or published via Netlify API.I'm working on cross-platform client apps using Tauri which will enable more publishing options as its not limited by what can be done in a client-only environment.The way the system works means that the Web doesn't need to be the only interface to the content - here's a simple Go-based CLI client that bypasses the HTML altogether https://github.com/sparktype-project/sparktype/tree/main/st-...It's very early days and there are still plenty of bugs, but I'm posting now to hopefully get feedback and see what people think. Please do let me know!

Could you build this?

Yes An in-browser static site generator and CMS can be assembled using browser storage (IndexedDB/OPFS), a client-side templating engine, and GitHub/GitLab API integrations.
