Instant launch
No bundled Chromium to spin up. Nop opens the instant you click — cold start feels warm.
Native HTTP client
Nop.
The HTTP client for the RAM apocalypse.
Nop is a fast, small, native, desktop app — without Electron, bundled browser, or gigabytes of overhead. It launches instantly and barely sips from your precious RAM. Gives you some RAM back to open more Chrome tabs.
While other clients eat your RAM…
Nop sips. Typical idle memory footprint:
Illustrative figures. Actual usage depends on your requests, collections and history.
Built to be barely there
Every byte earns its place. Nop is fast because it has almost nothing to slow it down.
Buttery smooth
Runs at your display's full refresh rate — 120 Hz, 144 Hz, whatever you've got. Silky on Retina and 4K screens.
Megabytes, not gigabytes
A self-contained binary that fits in a rounding error of the competition. Your RAM stays yours.
Local-first
Your requests, headers and collections never leave your machine. No account, no cloud, no telemetry.
No per-request pricing
Other clients charge you by the request or lock features behind a subscription. Nop is yours — send as many requests, collections as you want.
Built for capturing
Compose requests or capture live traffic through a local proxy. Inspect timing, headers and bodies side by side.
Get Nop
Pick your platform. All builds are self-contained — no runtime to install.
