Speler29

labs.speler29.nl
Personal dev lab for hosting live demos of my public git repositories. Not a sales page — just code, experiments, and things worth sharing in the browser.

Dave de la Roij (@speler29)

Building practical solutions for technical and operational problems. This domain mirrors my GitHub profile: small repos, browser demos, and tools that solve real friction.

What lives here

  • > Live browser demos linked to public git repositories.
  • > Small standalone apps — no login, no tracking, no pitch deck.
  • > Source on GitHub, demo on labs.speler29.nl.
