Watches a URL every 6 hours, hashes the page's text content (HTML tags and whitespace stripped so cosmetic edits don't trigger false alarms) and sends a Telegram alert only when it actually changes. Good for tracking a competitor's pricing page, terms of service, or product availability. Setup: point it at your URL, connect a free Telegram bot, 5 minutes.
Pay by card (Stripe) or USDC. Instant automatic delivery after payment — no account required. 7-day money-back guarantee: email deus@lumnika.com if it doesn't work as described.
