MONITOR SPIDER

Website change & defacement detection, synthetic login monitoring, and uptime alerts by email, Slack, Telegram and webhook. Start free.

MonitorSpider is a website monitoring service that goes beyond "is the server up?". It detects when your pages change or get defaced (recursive crawl + per-page content hashing), runs synthetic scripted logins to catch broken authentication that still returns HTTP 200, and monitors uptime, DNS records, SSL expiry, FTP/SFTP and SOCKS proxies. Debounced alerts reach you by email, Slack, Telegram or signed webhook, and each account gets shareable public status pages. Built for developers, agencies and MSPs managing one or many sites. Free tier (15 monitors); Premium $20/month flat.

A startup from Israel that is founded by Sebastian Sejzer.

Questions & Answers

As answered by people managing MONITOR SPIDER.

  1. Who are some of the biggest customers of MONITOR SPIDER?

    • Independent web agencies and MSPs monitoring client portfolios
    • Blockchain infrastructure operators monitoring node fleets
    • MonitorSpider itself

  2. What makes MONITOR SPIDER unique?

    MonitorSpider combines three monitoring jobs that normally require three separate subscriptions: uptime monitoring (like UptimeRobot/Pingdom), website change & defacement detection (like Visualping/Hexowatch), and synthetic login monitoring โ€” scripted logins that catch broken authentication even when the server still returns HTTP 200. It crawls your site recursively and hashes every page, so it alerts on what changed with a visual diff, not just "the homepage looks different". One flat plan, no per-check credits.

  3. Why should a person choose MONITOR SPIDER over its competitors?

    Because a green uptime check doesn't mean your site works. Competitors tell you the server responded; MonitorSpider also tells you when a page's content changed (defacement, broken deploy, hacked plugin) and when customers can no longer log in. Pricing is deliberately simple: a free tier with 15 monitors and email alerts, and one Premium plan at $20/month flat for 1,000 monitors, 1-minute checks, all monitor types, Slack/Telegram/webhook alerts and team seats, versus per-monitor or credit-based pricing that punishes agencies monitoring many client sites.

  4. How would you describe the primary audience of MONITOR SPIDER?

    Web agencies, MSPs and freelance developers who are responsible for many client websites, plus solo SaaS founders and sysadmins who want uptime, change detection and login monitoring in one tool. If a client's hacked homepage or broken login form is your phone call, MonitorSpider is built for you.

  5. What's the story behind MONITOR SPIDER?

    MonitorSpider started as an internal tool built by a systems engineer to watch his own production sites and client infrastructure. First: uptime and SSL. Then the checks he actually wished existed: "when any page on this site changes" and "log in as a real user every minute and tell me when that breaks". After years of working on real infrastructure, it was opened up as a self-serve product in 2026, keeping the flat pricing a small team would want to pay.

  6. Which are the primary technologies used for building MONITOR SPIDER?

    The old and stable PHP and MySQL stack. Monitoring covers HTTP(S), DNS, FTP/SFTP, SOCKS and SSL, recursive crawling with per-page content hashing for change detection, and agent/infrastructure metrics via Prometheus scrape, Nagios NCPA, and Telegraf push ingestion. Alert delivery integrates Slack, Telegram and HMAC-signed webhooks.
