Fast, modern API client for the browser

Test APIs Like a Pro

The lightweight API testing tool that gets out of your way. No accounts, no installs — just open and send.

"data": [...]
}

Why reqx?

API testing tools got bloated. We went the other way.

The old way

Slow startup, heavy RAM usage
Install on every machine
Paywalled features
Cluttered UI you never use

The reqx way

Instant, runs in your browser
Zero setup, just open & send
Completely free, forever
Clean UI, only what matters
