Define what should happen, where, and when — without changing your backend. Everything in NinjaWeb5 is built on a single model: a rule.
Every transformation, personalization, and control action in NinjaWeb5 follows the same four-part model. You don't write code — you describe behavior. The engine does the rest.
The event that activates the rule. Defines the moment in the request-response lifecycle when the rule is evaluated.
The context in which the rule applies. Conditions filter which requests and responses actually trigger the action.
The transformation applied to the HTML response. Each rule defines exactly one or more actions that execute on the matched content.
Execution control. Defines how this rule interacts with others — which runs first, which overrides, and how conflicts are resolved.
Each rule is a structured declaration — not a script. You define behavior in plain terms. Ninja executes it at the edge, for every matching request, in real time.
A request reaches the edge. Ninja evaluates the request context — URL, geo, device, headers.
All rules with matching conditions are identified. Priority is evaluated. Conflict groups are resolved.
Matched rules execute their actions in order — HTML is modified, content injected, metadata rewritten.
The transformed response reaches the browser. Rules are invisible to users — only the output changes.
The same rule model applies across every domain. One engine, four categories — everything flows through the same WHEN → WHERE → DO → WHY structure.
Rewrite title tags, inject schema markup, modify meta descriptions, and manage canonical URLs — in real time, per page.
SEO Layer →Block third-party scripts, enforce content policies, detect risky markup, and filter response headers before they reach the browser.
Security Layer →Inject banners, change CTAs, modify layout, and personalize the user interface for any segment — without touching source code.
UI Layer →Define A/B variants, assign traffic splits, and run experiments on any element of the page — launched instantly, paused the same way.
A/B Layer →Rules are defined through a structured visual interface. No IDE, no terminal, no deploy pipeline. Product managers, growth teams, and marketers can build and activate rules — without writing a single line of code.
Rewrite title tags, inject schema markup, modify Open Graph tags — per URL, per segment, or dynamically from a dataset. No CMS access needed.
Prevent third-party scripts from loading, reorder script execution, or enforce a content security policy — at the edge, before the browser parses the page.
Show segment-specific CTAs, geo-local pricing, and audience-matched messaging. Bind dataset values to variables and deliver them in real time.
Define A/B variants as rules. Set traffic split logic. Launch the experiment instantly — no staging, no deploy, no developer required.
Inject a promo banner, replace a hero image, hide a section, or change a button label — with a single rule, active within seconds of being saved.
Run any rule as a dry-run. Preview the output against a real page before activating. Confirm the result — then ship with confidence.
You don't write code.
You describe behavior —
and the edge executes it.
| Dimension | Traditional Approach | NinjaWeb5 Rule Engine |
|---|---|---|
| How behavior is defined | Hardcoded logic in backend or frontend | Declarative rules — WHEN, WHERE, DO, WHY |
| Who makes changes | Developers — every change needs a code edit | Anyone — product, growth, marketing |
| Time to activate | Deploy cycle — staging, review, release | Seconds — activate in the dashboard |
| Rollback | Another deployment or hotfix required | Pause or disable the rule instantly |
| Scalability | Each new condition adds code complexity | Add a rule — logic scales without code debt |
| Visibility | Logic scattered across codebase | All rules in one place — searchable, auditable |
Define a rule, activate it, and the change is live. No sprint, no release, no waiting.
Combine conditions, chain actions, and compose complex behavior from simple building blocks.
Add rules without adding code debt. The engine handles scale — you handle strategy.
Every rule can be paused in one click. Preview before activating. Zero risk to your origin.
Define behavior declaratively. Control output at the edge.
No code, no backend, no deployment.
