# [An AEO tool that changes what agents receive](https://rebilder.com/solutions/aeo-tool)

- **Updated:** 2026-09-10
- **Description:** Inspect your business information, connect source-backed responses and turn missing answers into an improvement queue.

Use Rebilder to inspect your pages, connect business information and act on incoming requests. Start with a free scan, then choose the reporting and managed features your team needs.



## What you get

- Score any URL against a published, deterministic spec
- See the exact markdown an agent receives, side by side with your HTML
- Connect source-backed responses with the self-hostable SDK
- Read the miss log: what agents asked for and did not get

## Turn findings into useful improvements

A useful tool helps you understand the evidence and complete the next action. Rebilder connects inspection, source-backed serving, request reporting and Answers management.

| Job | What it costs here | What it needs |
| --- | --- | --- |
| Score a URL | Free, no account | A URL |
| See what an agent receives | Free, no account | A URL |
| Serve agents markdown | Free to 1,000 agent visits a month | Source integration through the SDK |
| Read the miss log | The count and your three worst routes free; every route on Pro | The gateway running |
| Run it entirely yourself | Free, no account, no telemetry | The open SDK |

## What the tool actually does

The gateway renders configured source information for supported requests. Its rendering path runs without a model; source-backed drafting is a separate workflow.

middleware.ts

```ts
import { NextResponse } from 'next/server'
import { createGatewayProxy } from '@rebilder/gateway/next'
import { gatewayConfig } from '@/lib/gateway-config'

// Configure storeId and source resolvers in gatewayConfig.
export default createGatewayProxy(gatewayConfig, () => NextResponse.next())
```

On the reference product capture, that took a page from 91,226 bytes to 1,315 and moved the first substantive fact from character 23,185 to line 4, with the facts unchanged. There are adapters for common platforms, and the core has no framework dependency.

> **Self-hosted serving** The self-hosted SDK serves independently of your Console plan. Connect reporting and managed services for the operational features your team needs.

## How to evaluate any AEO tool, including this one

- **Ask what it changes.** If the answer is "it reports", budget for whatever will do the changing.
- **Check reproducibility.** Compare scores using the same captured evidence and ruleset; review changed responses and versions when results differ.
- **Ask to see the spec.** [Ours is published](/spec/ars), including the arithmetic, so a score can be checked rather than trusted.
- **Ask how citations are measured.** Identify the prompts, platforms and dates used in the report.
- **Check data handling.** The local scanner requests the target website and keeps scan results on your machine.

## What does an AEO tool do?

AEO tools support research, content improvement, technical inspection and measurement. Compare the specific workflow and evidence each provides.

## Is there a free AEO tool?

The gateway SDK is free to self-host. Paid plans add reporting, managed services and Answers operations.

## Do I need to change my CMS?

Use the adapter that fits your platform and connect your current sources. Verify the integration with your theme, analytics and checkout.

## Will this affect my search rankings?

Content negotiation serves your existing information in another format. Recognized search crawlers continue receiving canonical HTML.
