Getting started

Browser SDK

HTTP API

Quickstartbrowser.js

Install the browser SDK, identify the user, and send your first event. Autocapture starts on init, so page views, clicks, and forms flow without extra code.

import { initGFlux } from "@getfluxly/browser";

const gflux = initGFlux({ apiKey: "gflux_pub_live_xxx" });

gflux.identify("user_42", { plan: "pro" });
gflux.track("pricing_viewed");
Open the quickstart

Quickstart in ten minutes.

Three steps. Each one is independently useful: SDK, identity, triggered email.

Full quickstart
01 · Install

Drop the SDK in your app

npm install @getfluxly/browser or paste a script tag. 7KB minified, no peer deps.

Install guide
02 · Identify

Tie sessions to real users

Identity stitching
03 · Trigger

Send the right email at the right moment

Full changelog
FeatureMay 14, 2026

Computed traits, live

Define traits as a query over a user's event history (sessions in last 30 days, first paid plan) and use them in segments and templates.

ImprovementMay 9, 2026

Browser SDK 0.9

Smaller bundle (6.8KB to 6.1KB), keep alive batching on tab close, and an opt in consent gate before any auto capture fires.

FixMay 6, 2026

Stitching edge case fixed

Anonymous IDs created in incognito were occasionally orphaned during identify(). Profiles are now reconciled on the next event.
