Monitor Instacart for changes

Watch any Instacart 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 Instacart monitor in minutes

Point the recorder at a Instacart page, mark price change 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 Instacart page in the recorder

    Point the recorder at the Instacart page you care about and mark what to watch: price change, a CSS selector, or a visual baseline. Writ renders Instacart 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 Instacart account.

Three ways Writ monitors Instacart

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

How fast Writ checks Instacart, 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 Instacart change to an action in seconds

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

  1. 1
    Watch Instacart

    Pick the Instacart page and the change you care about: price change, 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 Instacart account.

◉

Notify any channel. Route a Instacart 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 Instacart questions

How fast can Writ check Instacart?
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 Instacart changes almost as they happen.
Is there a ready-made Instacart monitor I can install?
Point the recorder at the Instacart page, mark what to watch (price change, 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 Instacart?
Common targets include price change, item back in stock, new coupon. You can watch a specific element, the whole page, or a visual baseline, and Writ renders Instacart in a real browser so it catches values that load with JavaScript.
What happens when Instacart 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 Instacart account.
Is it allowed to monitor Instacart?
Use Writ on your own Instacart account, within Terms of Service. Authorized automation of your own ordering. 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.
