From SEO and QA to security and UI changes — apply rules in real-time without backend changes.
Inject and rewrite meta tags, Open Graph, structured data — without touching origin code.
Remove unsafe scripts, enforce CSP, sanitize HTML before it reaches the browser.
Assert DOM structure, inject QA banners, catch regressions before users do.
Swap heroes, inject variants, test changes at the edge with zero backend deploys.
Whether you're updating metadata for search, validating output before rollout, enforcing delivery policies, or injecting personalized content — the engine is the same. No origin code changes. No redeployments. Just rules running at the edge, at request time.
Browse solutionsEvery incoming HTTP request hits the Ninja edge worker before it reaches the origin server.
Rules are matched against request context — URL, headers, cookies, geo, and custom signals.
Matched rules trigger actions: scripts execute, datasets inject values, markup transforms.
The transformed response reaches the user — fast, accurate, and origin-independent.
Apply changes at the edge without touching your backend or redeploying origin code.
Ship experiments in hours, not sprints. Rules go live without code deployments.
Manage rules, scripts, and datasets from one console across any number of sites.
One rule engine covers all use cases — SEO, QA, security, and personalization together.
