Agent Ready is a free agent-readability checker for websites. Enter any public URL and it returns a 0โ€“100 score for how well AI agents, crawlers, and LLMs can understand and act on your site - plus a plain-English fix for every issue it finds.

It validates against the standards that govern the agentic web: โ€ข Vercel Agent Readability Spec - semantic HTML, metadata, structured data, content clarity โ€ข llmstxt.org - llms.txt and llms-full.txt discovery files โ€ข Agent-protocol manifests - MCP server cards, A2A, agents.json, agent-permissions.json, NLWeb, x402, and more

Results are grouped into Site, Page, llms.txt, and Protocol checks, each with a clear pass/fail and a remediation step, so developers can ship changes and re-scan immediately. A corpus benchmark shows how your site ranks against every other site scanned, and every scan gives you a shareable result URL and an embeddable SVG score badge.

Agent Ready is available wherever you work: web app, REST API, MCP server (Claude Desktop, Cursor, Cline, Goose, Continue), CLI (npm: agent-ready-scanner), client SDKs (npm + PyPI: agent-ready-client), and a browser extension for Chrome, Edge, and Firefox.

Freemium: scan free with no signup (3 scans/30 days anonymous, 10 signed in, 25 pages each). Pro ($19/month) adds deeper scans, history, monitoring, and API/MCP access. Built for developers, technical founders, and DevRel teams.

Questions & Answers

As answered by people managing devfair and Agent-Ready.dev.

Why should a person choose your product over its competitors?

Agent-Ready.dev's answer:

Most agent-readiness tools check a shallow list of well-known paths and produce inconsistent or false-positive results. Agent Ready validates against the actual published specs in depth, groups findings into Site / Page / llms.txt / Protocol layers, and gives a concrete remediation step for each. It scans free with no signup, shows how your site ranks against the whole corpus, and meets you wherever you work - API, MCP, CLI, SDK, or browser extension - not just a single web form.

How would you describe the primary audience of your product?

Agent-Ready.dev's answer:

Developers, technical founders, and DevRel teams preparing their websites for AI search and autonomous agents. Anyone who needs their site to be discoverable and usable by LLMs, AI assistants, and agentic crawlers.

What makes your product unique?

Agent-Ready.dev's answer:

Agent Ready is the only readiness checker grounded in the full set of agentic-web standards at once - the Vercel Agent Readability Spec, the llmstxt.org standard, and the major agent-protocol manifests (MCP, A2A, agents.json, NLWeb, x402). Independent scanners score the same site anywhere from 46 to 96 because they disagree on what to check; Agent Ready's value is spec fidelity and depth of protocol validation, with a plain-English fix for every issue. It's also available on every surface developers use - web, REST API, MCP, CLI, SDKs, and a browser extension.

What's the story behind your product?

Agent-Ready.dev's answer:

As AI assistants and autonomous agents became a primary way people find products and information, websites built only for human visitors started getting left behind - and there was no precise, standards-grounded way to know how "agent-ready" a site actually was. Agent Ready was built to fill that gap: a rigorous, spec-faithful score plus actionable fixes, so teams can prepare for the agentic web with confidence instead of guesswork.

Which are the primary technologies used for building your product?

Agent-Ready.dev's answer:

Next.js (App Router) and TypeScript, Tailwind CSS with shadcn/ui, Postgres for scan storage, deployed on Vercel. Standards/protocols implemented include the Vercel Agent Readability Spec, llmstxt.org, Model Context Protocol (MCP), A2A, agents.json, NLWeb, and x402.
