Website Change Detector Free
A free tier that watches a few pages before you pay for speed.

A website change detector free tier is enough to watch a few pages before you pay for speed. Free should mean a real check, not a watermarked screenshot that expires in three days.
AyeWatch Free Preview is six lifetime runs across three topics. Checks are Daily or slower. You get push and the in-app feed. No card. That is a proof, not a forever plan. If the first alerts are useful, Pro is $9 a month.
What "free" usually hides
Self-hosted ChangeDetection.io is free if your time is free. You run Docker, you patch it, you filter HTML noise. Chrome extensions are free until the laptop sleeps. Visual tools often cap checks or blur the overlay on the unpaid tier.
Read the tools roundup if you want the comparison table. This page is the free AyeWatch path: three topics, six runs, Daily.
What you give up until you pay
No email, Slack, Discord, or webhooks on Free Preview. No six-hour or ASAP interval. Six lifetime runs means you do not burn them on a noisy homepage. Use them on the URL you already babysit.
Paid plans add those channels and faster checks. Pro is 50 topics and six-hour checks. Pro+ is 150 topics and hourly. Max and Ultra are ASAP. Start free. Upgrade when the interval is the blocker, not the idea.

Try AyeWatch freeA fair free test
Pick one pricing page or one jobs URL. Write a tight rule. Wait for a real change or edit a page you control. If the summary is usable, the product class is right. If you needed a pixel overlay, you wanted a visual tool, and free AyeWatch will not become that.
Do not expect a Keepa-style history chart or an infinite check budget on the free tier. Expect a handful of real pings. That is the honest version of free. If you need charts of Amazon prices, stay on Camel or Keepa. If you need any other store's live page, the free AyeWatch proof is the right first hour. Upgrade when six runs or Daily checks are the wall. Free is a proof. Paid is the schedule.
