LIVE PREVIEW · NO BACKEND CHANGES · EDGE EXECUTION

Control HTML delivery
at the edge

NinjaWeb5 intercepts HTML responses at the edge, evaluates rules against request context, applies targeted transformations, and returns modified output to the browser — without touching origin code.

Rules

Define WHEN, WHERE and WHAT to transform. Match by URL, context, headers or any request attribute.

Logic layer
📌
Datasets

Inject structured values into rule execution — prices, variants, flags, geo data, user attributes.

Data layer
📝
Scripts

Run custom transformation logic — rewrite nodes, extract values, apply conditional modifications.

Transform layer
Edge Engine

Execute changes at delivery time, before the response reaches the browser. Origin stays untouched.

Execution layer

NinjaWeb5 intercepts HTML responses at the edge, evaluates your rules against request context, applies targeted transformations — and returns modified output to the browser without touching your origin code.

Teams use NinjaWeb5 to control exactly what gets delivered — from metadata and markup to full page transformations — without touching backend code or triggering deployments. The same rule engine powers SEO, QA, security, personalization, and experimentation from one centralized place.

Core Capabilities

Rules Engine

Evaluate conditions against any request signal and trigger precise actions on matching responses.

Edge Execution

Modify HTML responses at delivery time — before the browser receives them, after the origin sends them.

Datasets

Use structured data inside rules to inject dynamic values, localized content, and audience-specific output.

Scripts

Run custom JavaScript logic at the edge — transform markup, validate output, or call external services.

Dry Run

Simulate rule execution safely before going live — validate output, catch issues, and preview transformations.

Centralized Control

Manage all delivery logic — rules, scripts, datasets — from one console across any number of sites.

How it works

01
Request

A browser request hits the Ninja edge worker before reaching the origin server.

02
Ninja evaluates rules

Rules are matched against URL, headers, cookies, geo, and other request signals.

03
Actions / Scripts / Datasets

Matching rules trigger actions — scripts run, datasets inject values, markup transforms.

04
Modified HTML delivered

The transformed response is returned to the browser — fast, accurate, and without origin changes.

Architecture

Sits between browser and origin

NinjaWeb5 sits between the browser and the origin server and governs how HTML is delivered. Every request passes through the Ninja edge layer where rules are evaluated and transformations applied — before the response ever reaches the user.
