Introduction

Overview of FlashTraffic, key capabilities, and architecture.

Introduction to FlashTraffic

FlashTraffic is a next-generation desktop platform for simulating human web browsing, stress-testing web server capacity, and verifying web analytics tracking (Google Analytics 4, Plausible, Umami, PostHog, Mixpanel).

Built using Nuxt 4, Nuxt UI, and a high-performance Rust / Tauri 2 backend, FlashTraffic combines the power of local Playwright browser automation with real cloud mobile devices on BrowserStack.

Download FlashTraffic for Windows

SmartScreen Notice: As FlashTraffic is newly published, Windows Defender SmartScreen may display an "Unknown Publisher" dialog on first run. Click "More info" → "Run anyway". FlashTraffic is open source and built transparently via GitHub Actions.

Key Capabilities

Organic Search Attribution: Simulate search engine query referrer headers across Google, Bing, Yahoo, Yandex, Baidu, Naver, DuckDuckGo, and Ecosia.
Social Media & Inbound Referral: Simulate traffic origins from Facebook, X (Twitter), YouTube, LinkedIn, Instagram, Reddit, Pinterest, and TikTok.
GA4 UTM Tagging: Verify that custom utm_campaign, utm_medium, and utm_source tags populate correctly in your analytics realtime stream.
Human Physics Simulation: Natural cursor movement calculated with cubic Bézier equations, randomized reading intervals, and multi-page link surfing.
Proxy Orchestrator: Test proxy latency, rotate IP addresses automatically, and filter out dead endpoints.
Real Physical Device Matrix: Execute sessions on actual physical iPhones and Android devices via BrowserStack Automate API.
Portable & Offline-First: All data, campaigns, and credentials stay on your laptop. Export and import settings across computers via .json files.

High-Level Architecture
