Monitor Amazon for changes

Watch any Amazon page for the things that matter, and act the instant it changes. Monitors check as fast as every 10s on Scale; see the per-plan floors below.

Build a Amazon monitor in minutes

Point the recorder at a Amazon page, mark price drop or any selector, and Writ builds a Monitor that checks on a schedule and fires a workflow on a change, running on your own account, on a page you are authorized to use.

  1. 1
    Open the Amazon page in the recorder

    Point the recorder at the Amazon page you care about and mark what to watch: price drop, a CSS selector, or a visual baseline. Writ renders Amazon in real Chromium, so it sees values that load with JavaScript.

  2. 2
    Set the schedule and threshold

    Choose how often Writ checks (as fast as every 10s, 10s on Enterprise) and what counts as a change worth acting on.

  3. 3
    Connect a workflow to the change

    On a real change, an automation trigger runs a workflow: notify a channel, log the new value, or take an action on your own authenticated Amazon account.

Three ways Writ monitors Amazon

Content, availability, and dynamic values, all rendered in a real browser.

◈Content changeTrack a selector, the full page, or a visual baseline and get notified the moment Amazon changes what you're watching.
◈Uptime & SSLCheck that a Amazon page or your own Amazon integration is reachable, with response-time and certificate-expiry alerts.
◈JS-rendered valuesWrit renders Amazon in real Chromium, so it sees prices, stock, and status that load dynamically, not just the raw HTML.

frequency

How fast Writ checks Amazon, by plan

A faster cadence is a paid capability: a lightweight HTTP check costs far less than a full JS render, so the tightest intervals live on higher plans.

Plan Static page Dynamic (JS-rendered)
Free 5 min 15 min
Starter 60s 10 min
Growth 30s 5 min
Scale 10s 2 min

Enterprise checks down to 10s. Local and BYO runs carry no compute charge; cloud checks are metered from your plan’s included usage, and past it from your wallet.

From a Amazon change to an action in seconds

A Monitor detects the change; an automation trigger runs your workflow.

  1. 1
    Watch Amazon

    Pick the Amazon page and the change you care about: price drop, a selector, or a visual baseline.

  2. 2
    Detect the change

    Monitors check as fast as every 10s (10s on Enterprise). On a real change, an automation trigger fires.

  3. 3
    Act in seconds

    The trigger runs a workflow: notify a channel, extract the new value, or take an action on your own Amazon account.

◉

Notify any channel. Route a Amazon change to any of six providers (Email, SMS, WhatsApp, Signal, Pushover, or a custom webhook), or run a full workflow that takes an action on your own account.

Built on the same engine as the recorder and workflows.

Monitoring Amazon questions

How fast can Writ check Amazon?
It depends on your plan. Static-page checks run every 5 min on Free, 60s on Starter, 30s on Growth, and 10s on Scale; JS-rendered pages are slower (15 min down to 2 min), and Enterprise checks down to 10s. A detected change fires the connected workflow in seconds, so you act on Amazon changes almost as they happen.
Is there a ready-made Amazon monitor I can install?
Point the recorder at the Amazon page, mark what to watch (price drop, a selector, or a visual baseline), and Writ builds a Monitor that checks on a schedule and fires a workflow on a change. It takes minutes.
What can I monitor on Amazon?
Common targets include price drop, restock, buy-box change, new review. You can watch a specific element, the whole page, or a visual baseline, and Writ renders Amazon in a real browser so it catches values that load with JavaScript.
What happens when Amazon changes?
A change becomes an automation trigger that runs a workflow you choose: send a notification through one of six providers, extract the new data, push it to a destination, or take an action on your own authenticated Amazon account.
Is it allowed to monitor Amazon?
Use Writ on your own Amazon account and on public listings you have the right to access. Respect Amazon's Terms of Service and rate limits. These are Monitors and change detection on pages you are authorized to access. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.
