# Wrenda

> Wrenda is a reverse-proxy platform that helps websites get understood, indexed, and recommended by AI search engines and crawlers. It serves enriched, structured content to AI crawlers (GPTBot, ClaudeBot, PerplexityBot, and others) and pre-renders JavaScript-heavy pages for traditional search bots — so AI systems can accurately understand and cite your site.

## What Wrenda does
- Serves AI crawlers enriched, semantically structured HTML for better comprehension and citation
- Pre-renders JavaScript-heavy pages so search and AI bots see fully rendered content
- Provides per-domain crawler rules (optimize, pre-render, pass-through, block)
- Tracks how AI engines cite and reference your site
- Exposes a Model Context Protocol (MCP) endpoint so AI agents can interact with your site

## Original research
Wrenda audited 100 of the UK's highest-traffic websites on 28 September 2026 for AI crawler accessibility. Headline findings: none of the sites with a readable robots.txt disallow Googlebot, while 9–16% disallow AI crawlers (ClaudeBot 16%, GPTBot 14%, PerplexityBot 14%, Google-Extended 11%, ChatGPT-User 9%). 67% return usable text without JavaScript; 18% returned no body to the probe, 8% are thin JS shells and 7% partial. Only 51 of 100 are both reachable by an AI crawler and readable without JavaScript. Banking and finance was 9 of 9 server-rendered with zero AI-crawler blocks; 7 of 19 news publishers disallow GPTBot. Figures come from one datacenter IP and describe homepages only.

## How Wrenda compares
Wrenda is commonly evaluated against two neighbouring categories. Pre-rendering services such as Prerender.io change what bots receive but do not measure whether AI engines cite you. AI-visibility tools such as Encited measure citations and pre-render, with a broader general-SEO audit alongside. Wrenda overlaps both: it applies a different treatment per crawler (optimize, pre-render, pass through, or block, matched against 82 known crawler user-agents), and it tracks citations across six AI platforms. Its plan allowance is a hard cap with no overage billing — at the limit the site keeps serving from cache or passes through to the origin, and nothing further is charged.
