Website Uptime Monitor: What Went Down Since Last Run

Website Uptime Monitor - Check a list of sites on a schedule and see right away which ones went down, came back, lost their text or have an SSL certificate about to expire.

What does Website Uptime Monitor do?

Every row says what changed since the last run (went_down, recovered, status_changed, same) and shows SSL days left plus a 'page must contain this text' check per URL - the leading uptime checkers only return a status snapshot and ssl true/false.

• Went down / recovered / status changed vs the last run, per URL
• SSL expiry date, days left, issuer and an early warning
• Per-URL 'must contain' text check (url | text)
• Status, response time, redirects, page title, server
• Run never fails on a dead site - it reports why (timeout, DNS, SSL)

Who uses Website Uptime Monitor, and for what

• Agencies - see every morning which client site went down or lost its checkout button
• Shop owners - get warned two weeks before an SSL certificate expires
• Developers - run a post-deploy check that pages still show the right text
• Indie hackers - a cheap scheduled stand-in for Datadog synthetic checks

Why this Website Uptime Monitor?

Low tools return a bare status code once, so the user still has to compare runs and track certificate dates by hand. This Website Uptime Monitor checks every run and tells you plainly when a page could not be read, instead of returning empty or wrong rows.

FAQ

Does Website Uptime Monitor need a login, cookies or an API key? No. It reads public pages only.

Can I run Website Uptime Monitor on a schedule? Yes - with Apify Schedules; each run returns fresh rows.

Can I call it from Python, JavaScript or an AI agent? Yes - through the Apify API, the Apify client libraries or the Apify MCP server.

Is it legal? It collects only data anyone can see without logging in. You are responsible for using it within the source site's terms and data protection law (GDPR, CCPA).

What if the site blocks a request? The run retries from a fresh connection and, if it still cannot read the page, stops with a clear message - never with made-up rows.

Do I need proxies? No setup needed - Website Uptime Monitor uses Apify Proxy by default where the site needs it.

Troubleshooting

• No results: check the input (a public URL or a search term that returns results in a normal browser), then try the example input once.
• Fewer results than expected: raise the maximum in the input; some sites show only a part of their data without logging in, and Website Uptime Monitor never logs in.
• The run stopped with a message: the message says what the site answered; run it again later or with fewer items.
