Build a Instacart price tracker in minutes

Point the recorder at a Instacart page, mark the product price, and Writ builds a Monitor that reads it on a schedule and fires a workflow on a drop, running on your own account, on a page you are authorized to use.

  1. 1
    Open a Instacart item in the recorder

    Point the recorder at the Instacart page and mark the product price. Writ renders Instacart in real Chromium, so it reads values that load with JavaScript, not list-price theater.

  2. 2
    Set the schedule and target

    Choose how often Writ checks (as fast as every 10s) and a target price or percentage drop. Each check records the product price, building a real price history.

  3. 3
    Act on the drop

    A matching change fires a workflow: notify you across six providers, log the new product price, or trigger an optional approved workflow on your own authenticated Instacart account.

Guardrails on by default. Approved actions run behind a dry-run mode, a confirm gate, a rate limit, and idempotency, so one detected change never triggers the action twice. They run on your own authenticated Instacart account. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.

Approved actions are a cloud-only capability, gated by plan.

Instacart price tracking questions

How does Instacart price tracking work?
Writ sets up a Monitor on the Instacart page you choose and reads the product price in a real browser, so it catches values that load with JavaScript. It checks as fast as every 10s and records each reading, so you see a true price history and get alerted on a real change.
Is there a ready-made Instacart price tracker I can install?
Yes. Point the recorder at the Instacart page, mark the product price, and Writ builds a Monitor that reads it on a schedule. No catalog listing required; it takes minutes.
Can it act automatically when Instacart drops to my price?
Yes. A price drop can trigger an approved workflow on your own authenticated Instacart account. It runs with guardrails on by default: a dry-run mode, a confirm gate, a rate limit, and idempotency so one detected change never triggers the action twice.
How will I be notified of a Instacart price change?
Through any of six providers (Email, SMS, WhatsApp, Signal, Pushover, or a custom webhook), or by running a full workflow that records the new product price or pushes it to a destination.
Is it allowed to track prices on Instacart?
Use Writ on your own Instacart account, within Terms of Service. Authorized automation of your own ordering. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.
