rich multimedia content & lightweight animations
text-to-speech output in multiple languages
quizzes, surveys, and self-checks
online programming and executable examples
ASCII-art diagrams & dynamic charts
seamless JavaScript integration
collaborative and interactive classrooms

Open-courSe: like open source, but for courses

You stay in full control of your content — but by hosting your courses on GitHub, you make it easy for others to contribute, translate, and adapt them. There is no single source of truth, and there does not have to be only one course. With branches and forks you can evolve multiple variants for different languages, contexts, and target groups.

JavaScript-ready by design

Unlike most Markdown parsers, LiaScript lets you use any JavaScript library you like. Integrate visualizations, simulations, computer algebra systems, or custom widgets — whatever helps your learners.
To make this easy and reusable, LiaScript provides a powerful macro system that lets you wrap HTML and JavaScript into simple, author-friendly building blocks.

LiveEditor: collaborative authoring in your browser

The LiveEditor is a browser-based collaborative editor built specifically for LiaScript. Your content is stored locally in your browser; collaboration happens peer-to-peer via WebRTC and Yjs. Snippets for common LiaScript patterns are built-in — just type “lia” to discover them. And if you have a GitHub account, you can export your courses directly as gists with a few clicks.

Try the LiveEditor

How it works

Write in Markdown

Add LiaScript syntax where you want a quiz, a TTS voice, a runnable code block, or a chart. No template project, no dependencies to install.

Host the file anywhere

A GitHub repo, GitLab, Dropbox, IPFS, or a plain link. LiaScript doesn’t care where the text lives, since it renders in the visitor’s browser.

Share the link

Anyone opens it in a modern browser and gets the interactive course, no login and no server needed. Works offline once loaded, too.

Frequently asked questions

Do I need to install anything to write a course?

No. A LiaScript course is a plain Markdown file. You can write it in any text editor; the browser based Live Editor adds live preview and autocompletion if you want it.

Do I need to install anything to read a course?

No. Any modern browser renders the course directly from the Markdown file, no server or app required.

Is LiaScript free?

Yes, and it stays that way. LiaScript is developed in the open on GitHub; there’s no paid tier and no account requirement to create or run a course.

Where do I host my courses?

Wherever you already store text: GitHub, GitLab, Dropbox, a plain web server, or IPFS. There’s no LiaScript hosting service you’re locked into.

Can I use LiaScript without internet access?

Yes, once a course is loaded it keeps working offline, since everything runs client side in the browser.

Can I add quizzes, simulations, or my own JavaScript?

Yes. LiaScript supports quizzes, surveys, executable code blocks, and a macro system for wrapping any JavaScript library into reusable, author friendly blocks.

Can I use LiaScript courses in Moodle, ILIAS, or another LMS?

Yes, via the LiaScript Exporter, which packages a course as SCORM for import into common LMS platforms.

Can multiple people write a course together?

Yes, the Live Editor supports real time, peer to peer collaborative editing (WebRTC + Yjs), with no account or central server involved.

What if I already have a LiaScript file?

Paste its URL into the box on the homepage and it opens directly as a live course, no upload step needed.

Your next course starts as a text file

No installation, no build step, no account required. Write it in Markdown, drop in a quiz or a bit of JavaScript where you need it, and open the link in a browser.
