Developer builds 118+ browser-based device tests with no server uploads

By Meridian48 News Desk · Summarised from DEV Community ·

A developer created TestOnDevice, a collection of 118+ device tests that run entirely in the browser using Web APIs. The tool tests microphones, webcams, keyboards, and more without sending any data to a server. It requires no account, no installs, and all processing stays local.

Meridian48 take
The project is a practical showcase of modern browser capabilities, but its real value is in offering a privacy-respecting alternative to sketchy online testers.
