CrawlCheck vs Supademo: Which Is Better in 2026?

CrawlCheck is a free GEO (generative engine optimization) audit tool that shows exactly how AI crawlers see your website. Paste any domain and get an instant report: which of 61 AI crawlers are allowed, blocked, or ignored by your robots.txt, whether your llms.txt file exists and is well formed, and whether your sitemap is healthy and discoverable.

AI search is becoming a real traffic source. Chatbots like ChatGPT, Claude, Perplexity and Google AI Overviews fetch pages before they answer, and they obey very different rules from Googlebot. A robots.txt that looks fine for classic search can silently lock out GPTBot, ClaudeBot, PerplexityBot or Google-Extended, which means your content never enters the index behind those answers.

CrawlCheck checks all of this in one scan. You get a per-crawler breakdown that separates allowed, blocked and ignored agents, a check on your llms.txt and sitemap, and a short list of concrete fixes ordered by impact. Every scan produces a shareable report link you can send to a client, a developer or your team, so the fix list turns into a work item instead of a vague warning.

The report flags the exact user-agent lines that are missing or disallow rules that are too broad, points out a missing or malformed llms.txt, catches sitemap errors such as blocked entries or a stale lastmod, and gives copy-paste snippets for the most common setups, including Cloudflare, Next.js, WordPress and plain static hosting. Each finding is labelled with a severity level so you can fix the blockers first and leave the cosmetic items for later.

The tool is built for SEO teams, content marketers, developer-facing SaaS founders and indie makers who want their pages to be cited by AI search engines, not just ranked by classic search. It runs on Cloudflare Workers, needs no account, and returns results in a few seconds. Visit crawlcheck.dev to run a free audit on your own site.

What problem it solves

A robots.txt that looks fine for Googlebot can silently lock out GPTBot, ClaudeBot, PerplexityBot and Google-Extended, so your content never enters the index behind AI answers.

Alternatives & competitors

Manual robots.txt checkers, Screaming Frog, and generic SEO audit tools that do not model individual AI crawler user-agents.

Supademo is an AI-powered interactive demo platform that lets you show your product instead of just describing it. Rather than a passive video, viewers click through a real, guided walkthrough at their own pace — with branching, personalization and analytics baked in. More than 200,000 professionals use it to embed demos, power outreach and train users.

The idea behind Supademo

The problem it solves is simple: people understand a product far better when they can interact with it than when they watch a recording. Supademo captures your workflow and turns it into a clickable demo you can drop on a landing page, send in a sales email, or embed in help docs — so prospects and customers experience the product firsthand, on their own time.

Who's using it

Supademo spans the whole go-to-market org: marketing teams embed demos on landing pages, sales teams personalize them for outbound, presales and customer success use them in deals, and product teams lean on them for onboarding and internal training — across 25+ languages for customer education at scale.

What you get

• Interactive demo recorder that captures workflows into shareable demos
• HTML demo builder for pixel-perfect, code-free product clones
• Sandbox demo environments and a screen recorder
• Figma integration to turn prototypes into interactive demos
• Editor with annotations, tooltips, hotspots and branching
• AI personalization by audience, persona or account
• AI Demo Agents that autonomously guide prospects
• Engagement, drop-off and conversion analytics

Where the AI earns its keep

Supademo is AI-first in ways that save real time. Its AI Command handles bulk edits, voiceovers, translations and even analytics queries, personalization tailors a demo to a specific audience automatically, and AI Demo Agents can run autonomous conversations that guide a prospect through the product without a human present. For a small team, that's the difference between one demo and dozens of tailored ones.

Built to be shared and measured

A demo is only useful if it reaches people and tells you something. Supademo distributes via links, embedded pages and a browsable Demo Hub, integrates with HubSpot, Salesforce and Intercom, and tracks engagement, drop-off and conversion so you can see exactly where interest peaks or fades. Demos export to GIF, MP4 and PDF and work across desktop, tablet and mobile.

Pricing that won't punish reach

Supademo bills per creator seat, and crucially, viewers and views are unlimited on every plan — including the free tier. That means a demo can go viral on a landing page without your bill scaling with traffic, which is a meaningful contrast to tools that charge by views. Plans run from a free tier up through Business, Growth and Enterprise, with AI Demo Agents as a usage-based add-on.

Many ways to capture a product

Not every product demos the same way, so Supademo gives you several capture methods: an interactive recorder for live workflows, an HTML builder for pixel-perfect clones, sandbox environments, a screen recorder, and a Figma integration that turns prototypes into interactive demos before a feature is even built. That flexibility means teams can create the right kind of demo for the moment — a polished marketing walkthrough, a hands-on sandbox, or an early prototype tour.

Why teams pick it

Supademo has been named a G2 Demo Automation Leader for multiple consecutive quarters and is often cited as the easiest demo tool to use. For a team that wants to let buyers experience the product early — and to personalize and measure that experience without a big learning curve — it's a strong, AI-forward choice with pricing that rewards, rather than penalizes, getting your demo in front of as many people as possible.
