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.

Level Devil features and specs

  • Simple and Addictive Gameplay
    Level Devil features straightforward platformer mechanics that are easy to pick up but hard to master, making it highly addictive for players of all skill levels.
  • Unpredictable Challenges
    The game constantly surprises players with unexpected traps, shifting floors, and moving obstacles that keep the gameplay fresh and exciting throughout each level.
  • Free to Play
    Level Devil is accessible as a free browser-based game, meaning anyone can play it without needing to download software or pay for access.
  • Minimalist Design
    The clean, minimalist art style and simple controls make the game visually appealing and easy to understand without cluttered interfaces or overwhelming graphics.
  • High Replayability
    The difficulty and unpredictable nature of the traps encourage players to replay levels multiple times, providing a satisfying sense of accomplishment when finally completing a tough stage.

Possible disadvantages of Level Devil

  • Extremely Frustrating Difficulty
    The game's reliance on surprise traps and sudden deaths can feel unfair, leading to significant frustration especially for players who prefer skill-based challenges over trial-and-error gameplay.
  • Repetitive Mechanics
    Despite the surprise elements, the core gameplay loop of running, jumping, and dodging traps can become repetitive over extended play sessions with limited variety in mechanics.
  • Limited Content Depth
    As a simple browser game, Level Devil lacks the depth of a full platformer โ€” there are no storylines, character progression, or complex level design elements to keep players engaged long-term.
  • Trial-and-Error Design
    Many traps are nearly impossible to avoid on a first attempt, meaning success often depends on memorization rather than genuine skill, which can feel cheap and unsatisfying.
  • No Save or Progress System
    The game may lack robust save or checkpoint systems, meaning players can lose significant progress and have to redo sections they have already completed, adding to the frustration factor.

Questions & Answers

As answered by people managing Agent-Ready.dev and Level Devil.

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.
