Up and Running in Three Steps

No build-step required. Drop in the script, configure your destinations in the visual studio, and ship.

01

Install the Runtime

Add a single <script> tag. At ~14 KB gzipped, the smallest in the market and blazing fast.

02

Build Your Flows

Use our Unique drag-and-drop workflow builder to map events delivery without writing code.

03

Ship & Monitor

Publish in one click. Monitor events in real-time with built-in debugging tools.

Track your events in minutes

Build workflows visually, validate every step before you release, extend the graph with custom nodes, inspect each staging run in detail, and monitor live event delivery after publish.

  • Move faster with pre-built nodes

    Compose triggers, vendors, utilities, and branching logic without writing production glue code.

  • Debug before releasing

    Use Test Flow to simulate an event, open the run panel, and validate the workflow before you publish the runtime.

  • Extend the graph with custom nodes

    Start with official vendors, then add custom logic when your implementation needs something unique.

  • Inspect every workflow run in staging

    Replay executed events, inspect node properties, and review rendered inputs and outputs before pushing the flow to production.

  • Monitor live events after publish

    Track delivery health, volume, and failures from the same workspace after the flow goes live.

Everything You Need.
Nothing You Don't.

Smart Minification

We don't render or execute what's not used. Unused nodes are stripped from the runtime bundle.

Visual Workflow Builder

Drag and drop nodes on a canvas. Build complex routing logic visually — no code required.

Versioning

Every publish creates a snapshot. Roll back to any previous version in one click.

Got Questions? We've Got Answers

What exactly is Fluxyn?

Fluxyn is a lightweight (~14 KB gzipped) event routing platform. It captures browser events and routes them to marketing and analytics destinations like GA4, Meta, and Floodlight through visual workflow builder flows and server-aware delivery options.

Does Fluxyn work with my existing dataLayer?

Yes! Fluxyn intercepts dataLayer.push() calls natively. If you already have a dataLayer set up, Fluxyn will capture those events automatically — no code changes needed.

What about ad blockers?

Ad blockers affect any client-side setup. Fluxyn includes consent controls and can work with server-side delivery patterns to reduce client-side drop-off while keeping routing logic visible and manageable.

Can I create custom destination nodes?

Yes. Fluxyn supports custom nodes built directly on the canvas. Define inputs, write your transformation or delivery logic, version it, and reuse it across your flows.
