Support Responsive Test Tool

It's free, ad-free, and no-signup — on purpose. If it's saved you time, here's how to help keep it that way.

One-time or monthly — whatever works

Enjoying the tool?

Your support goes straight toward keeping it free, fast, and ad-free for everyone who uses it after you.

New to Buy Me a Coffee? It’s a simple, trusted way to send a small one-time or monthly tip — no account needed, and your payment details never touch this site.

Can’t chip in right now? Sharing helps too.

Where it goes

Domain, hosting & infrastructure

Covers the domain name and the servers that load every site you test — the recurring costs that keep the tool reachable at all.

New features

Compare and Device View both started as "it'd be nice if" ideas — coffee is what turns those into shipped features.

Staying free & ad-free

No paywalls, no account wall, no ad networks tracking you. Support is what makes that sustainable instead of temporary.
