Web Test
Check browser, HTML, CSS, JavaScript, forms, images, and small games across many environments.
Overview
Web Test is a small static site for checking whether a browser or operating system can connect to a web server, render basic HTML and CSS, run JavaScript, submit forms, handle text encoding, display common image formats, and run simple browser games.
Core browser checks
Test server connections, page loading, HTML and CSS rendering, JavaScript execution, and text encoding.
Media and favicon tests
Check whether JPEG, PNG, GIF, and favicon assets display correctly in the target environment.
Forms and input
Submit simple forms and verify input handling, form results, and character encoding.
Small browser games
Run Snake, Memory, and Reaction Time to check interactive JavaScript behavior and input response.
Install
Web Test has no build step, package manager, framework, CDN, web font, or external runtime dependency. Plain HTTP is useful for old browsers that cannot connect to current HTTPS servers.

Use it to check whether a browser, operating system, virtual machine, emulator, or low-spec device can handle common web features.
No. The pages use conservative HTML, CSS, and JavaScript so older browsers can still display and use the essential tests.
Yes. Clone or download the repository, start a local static server, and open the local address from the target environment.
The repository includes Snake, Memory, and Reaction Time mini-games.
