OverRider terms

Device profile

A stored description of one real device — user agent, screen size, platform, fonts, graphics hardware and more, across over 60 attributes. OverRider holds 100,000 and applies one per visit.

Engine

The browser automation stack a project uses. Engine-1 is Google Chrome driven by Puppeteer; Engine-2 is Chromium driven by Playwright.

Project

One traffic configuration: target URLs, traffic sources, engine, stop condition and schedule. Stored as a JSON file on your computer.

Thread

One simultaneous visit. The thread count is global and divided between running projects.

Stop condition

What ends a project — either a fixed duration or a target visit count.

Traffic source

A referrer page the browser loads before your site, which is what makes analytics assign a source and medium.

Qualified proxy

A proxy that has tested as working and matches your auto-select criteria. Only qualified proxies are chosen automatically.

Geo-matching

Deriving the browser language and timezone from the proxy’s exit country, so the two agree.

Browser and fingerprinting terms

Headless

A browser running without a visible window. OverRider always runs headless; the browser is otherwise fully functional, so JavaScript executes and analytics tags fire normally.

Fingerprint

The combination of attributes a site can read from a browser — screen size, fonts, graphics hardware, timezone and dozens more. Together these can identify a browser without cookies.

User agent

A text string the browser sends identifying its name, version and operating system. One of the oldest and weakest fingerprinting signals.

Canvas fingerprinting

Drawing hidden graphics and hashing the result. Small hardware and driver differences make the hash fairly distinctive. OverRider’s canvas noise option varies it per profile.

WebGL

A graphics API that exposes your GPU vendor and renderer strings — a strong fingerprinting signal, which OverRider can override per profile.

WebRTC leak

WebRTC can reveal your real IP address even behind a proxy. OverRider’s WebRTC protection prevents this and should stay enabled whenever you use proxies.

navigator.webdriver

A flag browsers set when under automation. Analytics platforms use it to filter automated traffic. OverRider always masks it.

Proxy terms

Proxy

An intermediary server that relays your requests, so the target site sees the proxy’s IP address instead of yours.

Public proxy

A free, unauthenticated proxy found by scraping. Unreliable and short-lived, with typical success rates of 20 to 40 percent.

Private proxy

A paid proxy requiring a username and password. Far more reliable.

Residential proxy

A proxy routing through a real consumer internet connection, so it carries ordinary IP reputation and is not filtered as data-centre traffic.

Data-centre proxy

A proxy hosted in a server facility. Fast and cheap, but the IP ranges are widely known and frequently filtered by analytics platforms.

Exit IP

The address the target site actually sees. Its country determines the geography your analytics reports.

SOCKS

A proxy protocol that forwards traffic at a lower level than HTTP proxies. SOCKS5 is the current version; SOCKS4 is older and lacks authentication.

Anonymity level

How much a proxy reveals about the original client. Transparent proxies pass your real IP through; elite proxies reveal nothing.

Analytics terms

Session

One continuous period of activity by a visitor. In OverRider, one visit produces one session.

New vs returning user

Analytics distinguishes these by a cookie set on a previous visit. Because every OverRider visit starts with an empty cookie jar, all traffic is recorded as new users.

Referrer

The page a visitor arrived from. With no referrer, analytics records the session as direct.

Source / medium

How analytics categorises a session’s origin, derived from the referrer — for example google / organic or facebook / referral.

Bounce

A session with no meaningful engagement. GA4 treats a session as engaged if it lasts over 10 seconds, records two or more pageviews, or converts — so OverRider traffic rarely bounces.

Engaged session

GA4’s replacement for bounce rate. Default OverRider stay times clear the threshold on every visit.
