AI + SEO + Social · 29+ bots · ~200ms · Zero config · Any theme & page builder

25% of Google queries now trigger AI Overviews. If ChatGPT can't read your site, it will never recommend you. If Google can't see your JavaScript-rendered content, you're losing rankings.

Modern sites rely on JavaScript for everything — page builders, lazy loading, WooCommerce, dynamic widgets. But AI crawlers like GPTBot and ClaudeBot don't execute JavaScript at all. Google does, but with delays of hours to weeks.

Prerex fixes this. When any bot visits your site, it gets a fully-rendered version — every image loaded, every script executed, all content visible. Your visitors notice nothing. Bots see everything. AI cites you.

Prerex doesn't do SEO for you. Prerex makes sure the SEO you've already done actually works — for Google, for ChatGPT, for every bot that matters.

• WordPress 5.8+
• PHP 7.4+

Built by engineers, not marketers.

• Cloud rendering engine with sub-second response times — pages served in ~200ms from edge cache
• DNS-verified bot detection — reverse + forward DNS lookup confirms every bot is genuine. No spoofing gets through.
• Adaptive wait technology (Rex Sense) — captures content when it's truly ready, not on a fixed timer. Handles lazy-loaded images, AJAX calls, and deferred scripts.
• Three-tier network isolation — the rendering sandbox never touches your data. Separate networks for public traffic, internal services, and database layer.
• SSRF protection — URL validation blocks private IPs, DNS rebinding, octal notation, and internal hostnames. Rendering can't be weaponized.
• Every input validated — all API endpoints enforce strict schema validation. Every user-submitted regex checked for catastrophic backtracking (ReDoS).
• Credentials hashed at rest — bcrypt for passwords and API keys, SHA-256 for verification codes. Nothing stored in plaintext.
• Revocable sessions — JWT tokens can be invalidated instantly on logout or password change. No stale sessions.
• Rate limiting everywhere — login, registration, rendering, webhooks. Multi-layer: application-level per key, infrastructure-level per IP.
• HTML cleanup pipeline — strips scripts, styles, event handlers, and tracking pixels. Preserves JSON-LD, Open Graph, images, and semantic structure. Pages up to 80% lighter.
• Smart cache integration — coexists with WP Super Cache, WP Rocket, W3 Total Cache, LiteSpeed, and any object cache. Ensures bots always get fresh rendered content without disrupting your existing cache setup.
• 154 automated tests, zero tolerance for regressions

We don't ship features. We ship guarantees.

Prerex detects and serves optimized content to 29+ bot families across 4 categories:

Every bot is verified using reverse + forward DNS lookup — not just user-agent matching. This means:

• crawl-66-249-66-1.googlebot.com → Verified Google bot → Served
• fake-googlebot.com → DNS mismatch → Blocked
