Direct answer
How much does ChangeTower cost?
ChangeTower runs a free tier plus paid plans, and the practical cost driver is not the headline price — it is how many URLs you watch and how often each one is checked.
- Change-detection tools price on monitored-page count and check frequency, so a low entry price can still be expensive across a client portfolio.
- Check the shortest interval on the plan you are pricing — hourly versus daily changes the tool's usefulness for pricing or stock pages entirely.
- Always price the plan you would actually run, not the entry tier, before comparing vendors.
