Three things that matter when you're choosing a monitoring tool for the long run.
ChangeTower captures what changed — it shows you text snapshots and visual screenshots. Watchobots takes the next step: it reads the change in context and generates a plain-English summary with a High, Medium, or Low importance score. You know immediately whether to act on it, without opening the page and comparing screenshots.
ChangeTower needs Zapier to connect to Slack, and Discord only works through a generic webhook you wire up yourself. Watchobots has both built in natively — paste your Slack or Discord webhook URL in Settings and you're done, with formatted, color-coded alerts out of the box. No third-party tool, no manual setup.
Watchobots' $9/mo Starter plan keeps 90 days of change history. ChangeTower's closest-priced plan, Lite at $12/mo, only keeps 30 days — if you ever need to look back further than a month, that data's already gone.
2 pages, no credit card, no setup. If you've been using ChangeTower, you'll be up and running in under 2 minutes.
