SiteMonit is a website change monitoring tool that renders pages in a real browser and produces a before/after diff for every check, including a Diff Axis change map and a Text mode that marks additions and deletions like tracked changes. Users can monitor a whole page or select a specific element/area, filter alerts by keyword, and schedule checks from monthly down to every 15 minutes on paid plans. Alerts are sent via Email, Telegram, Slack, Viber, Discord or webhook, each linking directly to the before/after diff. It offers a free plan plus paid subscription tiers and a pay-as-you-go top-up for extra checks.

Pricing
The pricing page includes a free plan and an enterprise/custom option for users needing more than 50k checks a month. Exact paid-tier prices are not publicly listed. There is a discrepancy between the site's description of the free plan (checks every 15 minutes) and the FAQ (15-minute checks only on paid plans).
Site advertises a free plan ('Get Started for Free', 'Start Monitoring — Free'); paid tier prices are rendered dynamically via template variables on the pricing page and are not stated as static text.
Yearly billing saves ~15% compared to monthly billing.
