# What is Serverside monitoring?

**Serverside Monitoring** has been reintroduced to Stellar, offering an additional layer of restock detection across supported sites like **Amazon, Walmart, Costco, Sam’s Club** and others.

This feature allows Stellar to detect restocks directly from our servers, reducing the chance of missing drops when your local monitor tasks are rate limited or throttled.

***

**How It Works**

* **No Setup Needed** – Just make sure your bot is on the latest version. It will automatically listen for Stellar's serverside pings.
* **Enhances Local Monitoring** – Serverside monitoring works *with* your monitor tasks, not instead of them. Continue running **one monitor task per product** as usual.
* **Use "Watch Tasks"** – Ensure your checkout tasks are set as Watch Tasks to take advantage of serverside triggers.
  * Amazon checkout tasks are watch tasks by default

***

**Where to Check for Supported Products**

* Since supported SKUs can change frequently, we do **not** list them in this guide. You can open a ticket in our Discord server to find out which SKUs are supported.

***

**Why It Matters**

* **Faster Detection** – Receive instant pings from Stellar’s backend, helping you stay ahead during high traffic drops.
* **More Reliable** – Minimizes missed restocks from local monitor rate limits or blocks.
* **Optimized for Key Retailers** – Supported on major retail sites including **Amazon US, Walmart US & CA, Costco US & CA and Sam’s Club**.

***

**Request a Product**

If there’s a high demand item you'd like monitored via serverside, open a ticket, we’ll review and add it if eligible.

***

**Final Tips**

* **Keep Running Local Monitor Tasks** – Serverside is an enhancement, not a replacement.
* **Stay Updated** – Our supported sites and SKU lists are updated frequently behind the scenes.

This system helps ensure faster, more reliable restock detection while reducing your chances of missing drops.
