About 4mapper

4mapper is a browser‑based projection mapping tool for visual artists, performers and small events.

What 4mapper is

4mapper was created to make projection mapping accessible without expensive software or complex setups. It runs directly in the browser, so you can start mapping in a few minutes without installing anything.

The focus is on a playful, visual workflow: upload your media, map it to your surfaces, add live widgets, and project.

Core principles

• Accessible – learn and experiment without paying hundreds of euros for pro tools.
• Browser‑first – no installation, cross‑platform, easy to use at home, in studios and schools.
• Live data & sensors – connect widgets, APIs and Arduino sensors to create reactive installations.
• Friendly to beginners – made for designers, students, performers and makers, not only professional VJs.

Who is behind 4mapper

4mapper is an independent project developed and maintained by a single developer based in Italy. The goal is to build a focused tool for creative people who want to explore projection mapping without friction.

If you use 4mapper in a show, installation or experiment, it is always great to see it in action. You can share screenshots, videos or feedback by email.
