Automate Website Data Extraction with AI
Thunderbit helps you scrape data from websites while you browse, using AI Suggest Fields to detect the right columns and formats. Collect structured results from listings, directories, and paginated pages, and enrich rows by scraping subpages for deeper details.
Scrape content from PDFs, docs, and images, then summarize, categorize, or standardize fields as part of extraction. Export your data to Google Sheets, Airtable, or Notion, or download as CSV or JSON for your workflows.
How to Check Website Status Using Thunderbit
STEP 1Download and InstallDownload and install the Thunderbit Chrome Extension from the Thunderbit Chrome Extension Download Page. Once installed, log in or create a free account to get started.
STEP 2Open ExtensionOpen Chrome and go to the tool tab labeled "Check a Website URL". Open the Thunderbit Chrome Extension, then select the "Website Down Checker" tool. In the input field named "url", enter the website address you want to verify (for best results, include https://, such as https://example.com).
STEP 3Click the Check website status ButtonClick the "Check website status" button. Thunderbit will test whether the URL is reachable and return a plain-text report that includes the overall status (Up or Down), the final URL attempted, the HTTP status code when available, response time in milliseconds when available, and a short explanation (such as redirect, timeout, DNS failure, or SSL error). Copy the results for sharing, or paste them into your documentation or a spreadsheet as needed.
Learn how to check whether a website is down or reachable
Check website availability by URL
Enter any website URL or domain to verify whether the site is reachable right now. Website Down Checker helps you confirm if an outage is real or if the issue is on your side, such as Wi-Fi, VPN, DNS, or browser settings. It’s built for support teams, marketers, sales reps, and operators who need a quick, reliable status check before escalating an incident.
Diagnose the reason with clear status details
Get a concise report that explains why a site is Up or Down, including common causes like HTTP 200/301/302 responses, timeouts, DNS failures, SSL errors, or connection refusals. When available, it also returns the HTTP status code and response time in milliseconds. If you paste only a domain, it tries https first and then http to reduce false downtime reports.
Triage incidents and reduce back-and-forth
Use the output to decide your next step: retry later, switch networks, disable VPN, or contact the site owner or hosting provider with concrete evidence. Support and IT teams can paste the status report into tickets, while account managers can share it with customers to set expectations. The standardized fields make it easy to compare checks across multiple sites and times.
Monitor critical pages during launches and campaigns
Run quick checks before and during product launches, email sends, paid ads, or major content updates to confirm landing pages are reachable. Ecommerce and operations teams can validate storefront uptime, while marketing teams can verify tracking and redirects are responding as expected. The response time and status code help spot slowdowns or misconfigured redirects before they impact conversions.
