Build a Kayak price tracker in minutes

Point the recorder at a Kayak page, mark the flight fare, 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 Kayak item in the recorder

    Point the recorder at the Kayak page and mark the flight fare. Writ renders Kayak 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 flight fare, 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 flight fare, or trigger an optional approved workflow on your own authenticated Kayak account.

Kayak price tracking questions

How does Kayak price tracking work?
Writ sets up a Monitor on the Kayak page you choose and reads the flight fare 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 Kayak price tracker I can install?
Yes. Point the recorder at the Kayak page, mark the flight fare, and Writ builds a Monitor that reads it on a schedule. No catalog listing required; it takes minutes.
Can it act automatically when Kayak drops to my price?
Yes. A price drop can trigger an approved workflow on your own authenticated Kayak 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 Kayak 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 flight fare or pushes it to a destination.
Is it allowed to track prices on Kayak?
Collect Kayak data you have the right to access and respect its Terms of Use and rate limits. Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.
