Frequently Asked Questions
Everything you need to know about CheckSite
CheckSite visits your specified websites at regular intervals and captures the page content. When meaningful changes are detected — like price updates, new listings, or content modifications — you get an instant notification with a clear summary explaining what changed and why it matters.
Any publicly accessible website: e-commerce stores, competitor pricing pages, real estate listings, API documentation, news sites, job boards, government pages, and more. If it loads in a browser, CheckSite can monitor it.
Most tools just diff raw HTML and flood you with noise. CheckSite uses intelligent analysis to understand context — it knows a price change matters more than a timestamp update. You get smart summaries that explain what actually changed, not a wall of code.
Free users get daily checks (every 24 hours). Pro users can choose hourly, every 4 hours, 8 hours, or daily. The moment a meaningful change is detected, you receive an instant notification via your preferred channel.
Free plans include email notifications. Pro plans unlock all channels: Email, Telegram, Slack, Discord, Teams, and Webhooks. You can configure different notification preferences for each monitor.
Yes — all plans include intelligent summaries. Every notification explains exactly what changed, like "Price dropped from $99 to $79" or "3 new job listings added." Pro users get additional features like custom monitoring prompts and faster check frequencies.
If you reach your website limit (3 on Free), you won't be able to add new monitors until you upgrade or remove existing ones. Your active monitors continue working normally.
Absolutely. You can upgrade, downgrade, or cancel at any time from your account settings. No long-term contracts, no cancellation fees. We also offer a 30-day money-back guarantee on all paid plans.
