Beacon

A fast alternative to Postman and Insomnia. Compose requests, script tests, mock APIs and inspect responses down to the TLS handshake — all stored locally.

What it does

Built around a few ideas

Keyboard-first

Built to be driven from the keyboard. Requests, collections and environments without reaching for the mouse.

Full timing waterfall

Every response breaks down into DNS, TCP, TLS and TTFB, so you can see where the time actually went.

Flows and load testing

Chain requests on a visual canvas, then run the same request under load and watch the numbers.

Local by default

Everything lives on your machine, and signing out clears it for the next person — after saving an encrypted backup first. Optional end-to-end encrypted sync if you want your data across devices.

Install

Getting it running

Homebrew (recommended)

brew tap jeet427/beacon && brew install --cask beacon

Worth knowing: Beacon is an indie project without a paid Apple Developer subscription, so it is not notarized. Installing via Homebrew handles this for you. If you download the DMG directly, macOS will refuse to open it the first time — run `xattr -cr /Applications/Beacon.app` once and it will open normally after that.

Questions

Before you click through

Is Beacon free?

Yes. Beacon is free to download and use, no account required.

Why does macOS say Beacon "cannot be opened"?

Beacon isn't notarized by Apple — that requires a paid $99/year developer subscription this indie project doesn't have. Installing via Homebrew clears the quarantine flag automatically. Downloading the DMG directly needs one manual step: run `xattr -cr /Applications/Beacon.app` in Terminal, once.

Does Beacon send my requests or data anywhere?

No. Collections, environments and history are stored locally on your machine. Requests go directly from your machine to whatever API you point Beacon at, the same as any HTTP client — nothing passes through a server Beacon operates.

Does Beacon run on Linux?

Not currently — builds are published for macOS (Apple Silicon and Intel) and Windows.
