Your prioritized fix list

The fix, done for you

Don't do the homework. Let Arachne compile it.

Arachne compiles your site into a Shadow API — a native MCP server, an OpenAPI surface, and an agent policy — without you touching your codebase. Preview the exact Shadow API we'd build for you, right now.

Make it live

$500one-time setup + $99/mo hosted
  • Setup: compile, domain-ownership verification, initial tuning
  • Monthly: hosting, re-sync as your site changes, hash-chained metering ledger

We'll verify your domain and get your Shadow API live. No charge until your build is scheduled.

Quick answers

The questions buyers ask most often before clicking unlock.

Doesn't this make my site more vulnerable to AI agents?

Your front door is already open. Arachne replaces it with a glass door and a guest log.

Agents are scraping your site right now, anonymously and unauditably. Arachne doesn't make them possible — it makes them visible and accountable. Writes default to draft_only and require explicit approval. Page content is flagged as data, not instructions (the canonical defense against prompt injection). Every call lands in a hash-chained audit ledger you can re-walk. You're trading invisibility for accountability.

How is my score calculated?

Deterministic, 7 weighted signals, max 100. Each is binary — full weight or zero. The weights sum to 100.

The full $49 report breaks down exactly which signal you missed, why it matters, and your projected score after Arachne compiles a Shadow API.

What happens after I pay the $49?

Instant redirect to your full report — every readiness signal scored with the specific detail, a prioritized fix list, and your projected score after Arachne. Plus a live preview of the Shadow API we'd compile for your domain (real manifest, real tools), and the option to commission a hosted build.

Is the $49 a subscription?

No. One-time, per domain. You only enter subscription territory if you commission a hosted Shadow API ($500 setup + $99/mo), and that's an explicit separate decision on the next page.

What MCP client do I need?

The Shadow API works with any MCP-capable agent. Most common: Claude Desktop, plus Claude Code, Cursor, Continue, and custom agents built with LangChain MCP adapters or the OpenAI Agents SDK. One URL, every client.

Do you need access to my codebase?

No. Arachne is fully egress-side — we only see what a normal browser sees on your public site. Domain ownership is proven via a single DNS TXT record. We never touch your code, your database, or your auth system.
