Live Lesson Lab
An interactive online classroom platform where teachers and trainers embed runnable code examples in their slides and worksheets, recompiling instantly in the browser so students see results the moment a concept is explained.
Computer science teachers, coding bootcamp instructors and corporate trainers who lecture and demo code in class
- Embeddable runnable code blocks that recompile inside a slide or worksheet on every keystroke
- Library of starter templates for Scheme, Python, JavaScript and a visual output pane
- Class dashboard showing which students ran which examples and where they got stuck
- Shareable assignments that students open in a browser tab with zero setup
Goeteia shows a working compiler can run entirely in the browser in milliseconds, removing the install-and-configure friction that turns the first 20 minutes of every coding class into dead time — a teacher-facing product on top of that capability addresses a daily pain.
Validated demand — CapyClass, Codeboard, Codesters, LiveCodes, and Replit for Education all serve the same teacher/instructor audience with browser-based coding classrooms; LiveCodes explicitly targets 'schools, colleges, and coding bootcamps' as a free open-source playground.CapyClass — Interactive Coding Classroom Platform ↗LiveCodes for Education | LiveCodes ↗
Crowded niche — LiveCodes (open-source, free, 80+ languages with embeddable playgrounds), Codeboard, CapyClass, CodeSlides, Demo Time, and CodeSlide (Slidev + code-server) all overlap with 'runnable code in slides/classroom'; Replit even deprecating Teams for Education is a bearish signal for new entrants.Replit Teams for Education Deprecation: All you need to know ↗Stop Alt-Tabbing: Embed a full IDE for live coding in your slides ↗
Weak willingness to pay — Replit Education is free for verified teachers, LiveCodes is fully free/open-source, and bootcamp instructors typically use free tools; Replit Teams for Education was launched then shut down, suggesting classroom plans are hard to monetize profitably.Replit Pricing 2026: Plans, Costs & Free Options | AISO Tools ↗
Durable — coding education demand is structural, browser-based compilers (Pyodide, WASM Scheme, etc.) continue improving, and edtech lock-in with institutions supports multi-year retention.LiveCodes for Education | LiveCodes ↗
Moderate — browser compilers and embeddable editors already exist (LiveCodes SDK, Pyodide, CodeMirror), but combining a polished slide/lesson tool with shared live execution and instructor controls requires meaningful product work beyond wrapping existing building blocks.CodeSlides - Present your code with animations ↗Demo Time - Never stress about live coding again ↗
