What we found

Agent Checker starts with a quick protocol scan, then offers a full audit where a real AI agent uses the site in a browser and reports task-level problems.

- Agent Checker says it sends a real AI agent to a website and scores it against WebMCP, llms.txt, Core Web Vitals, and structured data.
- Its free quick check is described as a static scan of 20 protocol surfaces that returns in about 60 seconds.
- Its paid full audit says a real AI agent drives a browser through tasks such as search, signup, checkout, contact, support, and error handling.

Choose CanAgentUse when

- You need broad coverage across crawler policy, llms.txt, schema, semantic HTML, APIs, OAuth metadata, MCP, A2A, WebMCP, UCP, and x402.
- You want focused validators and public suite docs that technical owners can inspect.
- You need a readiness workflow before choosing whether to run deeper agent task tests.

Choose Agent Checker when

- You want to see whether a real browser-driving agent can complete user tasks.
- You need click replay and task-level evidence for navigation, forms, checkout, signup, or contact flows.
- You are comfortable with a free quick check plus a paid full audit model.

Comparison matrix

CanAgentUse vs Agent Checker

Vendor pricing and packaging move quickly, so this table sticks to the product job, output, and team fit.

Criterion	CanAgentUse	Agent Checker
Primary job	Audit whether a public site exposes the crawl, content, metadata, API, protocol, and commerce signals agents need.	Agent Checker combines a static quick check with a paid full audit that drives a real AI agent through browser tasks.
Check depth	Broad checks across crawler policy, llms.txt, schema, semantic HTML, OpenAPI, OAuth, MCP, A2A, WebMCP, UCP, x402, and more.	Public pages usually show a smaller or more specialized check list. Test the report before assuming parity.
Output style	Evidence-led reports with issue details, fix guidance, public reports, exports, and focused validators.	Often a score, quick scan, app report, implementation offer, or visibility dashboard depending on the product.
Team fit	SEO, product, engineering, ecommerce, platform, and developer relations teams that need fixable evidence.	Teams that want a quick scan, a narrower tool, or an implementation-specific path.
Pricing and packaging	Public scanners are available. Product, plugin, and workflow pricing depends on scope.	Check the vendor site before buying. Plan names, free limits, and paid implementation offers change.

Other tools worth checking

CanAgentUse

Deep technical AI readiness audits across content, discovery files, APIs, protocols, and commerce signals

CanAgentUse is for teams that need proof. It checks whether crawlers can reach the site, whether AI systems can parse the page, and whether agents can discover usable actions.

Works well for

- Covers crawler policy, llms.txt, schema, semantic HTML, OpenAPI, OAuth metadata, MCP, A2A, WebMCP, UCP, x402, and related agent signals.
- Returns evidence and fix guidance that SEO, product, and engineering teams can act on.
- Includes focused validators for AI crawler compatibility, llms.txt, MCP, A2A, UCP, and agent website structure.

Watchouts

- It is not a keyword database, backlink suite, or generic brand mention tracker.
- It goes deeper than a quick free scanner, so the best value comes when a team plans to fix the issues it finds.

Profound

AI answer visibility and executive market intelligence

Profound is mainly a visibility platform. Use it when the question is where your brand appears in AI answers and how that compares with competitors.

Works well for

- Good fit for answer share, competitive visibility, and reporting for leadership.
- Useful when the site foundation is already healthy and the next question is market presence.

Watchouts

- Visibility reporting does not prove that crawlers, schema, APIs, MCP, or checkout flows work.
- Technical teams may still need a readiness scan before chasing visibility gaps.

Peec AI

AI search analytics and prompt monitoring

Peec AI is useful when a marketing team wants to track brand presence in AI search and compare that presence with competitors.

Works well for

- Strong match for prompt monitoring and AI search reporting.
- Easy to explain to brand, growth, and content teams.

Watchouts

- Prompt visibility does not diagnose agent protocol readiness.
- Engineering teams still need separate checks for crawler access, schema, OpenAPI, MCP, and authentication metadata.

Scrunch AI

AI search presence and customer journey analysis

Scrunch AI focuses on how brands appear during AI search and buying journeys. It is a marketing visibility tool more than a technical website audit.

Works well for

- Good fit for demand teams studying AI-assisted discovery.
- Useful when content opportunities and journey visibility matter most.

Watchouts

- Journey visibility does not validate machine-readable contracts.
- A technical scan is still useful for protocol, API, metadata, and crawler problems.

OtterlyAI

AI search monitoring, prompts, links, and brand mentions

OtterlyAI fits teams that want to watch brand mentions and citations across selected AI search prompts.

Works well for

- Good starter layer for AI search monitoring.
- Useful when the buyer wants mention tracking before deeper technical work.

Watchouts

- Mentions do not show whether an agent can fetch, parse, authenticate, or act on the site.
- Technical remediation needs a different kind of report.

SiteSpeakAI Agent Readiness Scanner

A quick scan tied to SiteSpeakAI's chatbot and WebMCP product

SiteSpeakAI checks for signals such as WebMCP, llms.txt, structured data, and content quality, then points users toward its agent and chatbot setup.

Works well for

- Simple free entry point for teams learning what AI agent readiness means.
- The page explains WebMCP and llms.txt in plain terms.

Watchouts

- It is closer to a quick scanner and product lead-in than a full evidence report.
- Teams that need many protocol checks, exports, or engineering detail may outgrow it.

FAQ

Is CanAgentUse a direct Agent Checker replacement?

Only for the readiness-scanning side. CanAgentUse goes broader on protocol, API, commerce, and suite documentation. Agent Checker has a different strength when the buyer wants a real browser task audit.

When should I run Agent Checker and CanAgentUse together?

Use CanAgentUse first to find missing discovery files, crawler rules, schemas, APIs, and protocol metadata. Use Agent Checker when you also need to know whether an agent can complete live tasks such as search, checkout, signup, or contact.
