Build a Craigslist price tracker in minutes

Point the recorder at a Craigslist page, mark the item 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 Craigslist item in the recorder

    Point the recorder at the Craigslist page and mark the item price. Writ renders Craigslist 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 item 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 item price, or trigger an optional approved workflow on your own authenticated Craigslist account.

Check cadence by plan

How often Writ checks Craigslist is set by your plan. Static pages check faster than pages Writ has to render in a full browser.

{ }

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 Craigslist 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.

Craigslist price tracking questions

How does Craigslist price tracking work?
Writ sets up a Monitor on the Craigslist page you choose and reads the item 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 Craigslist price tracker I can install?
Yes. Point the recorder at the Craigslist page, mark the item price, and Writ builds a Monitor that reads it on a schedule. No catalog listing required; it takes minutes.
Can it act automatically when Craigslist drops to my price?
Yes. A price drop can trigger an approved workflow on your own authenticated Craigslist 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 Craigslist 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 item price or pushes it to a destination.
Is it allowed to track prices on Craigslist?
Collect Craigslist 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.
