# Queuing

Use **Run Queue** when you need to see which runs are waiting to start, which ones are already running, and how much account concurrency is currently in use.

## Overview

The queue lives in your workspace sidebar, not as a separate page. It gives you a live view of active queue items for your account, including whether each item is still waiting for a slot or already using one.

Fetch Hive uses queueing when a run cannot start immediately because your account is already at its concurrency cap. For the current plan-based concurrency caps and `429` responses, see [Errors and rate limits](https://docs.fetchhive.com/api-reference/errors-and-rate-limits).

## How do I open the queue? <a href="#open-queue" id="open-queue"></a>

In the left sidebar footer, click **Run Queue**.

If Fetch Hive already has active queue items, the **Run Queue** button can show a count badge so you can see there is work in progress before you open it.

The sheet opens on the right side of the app and shows active queue items plus current concurrency usage.

## How do I read queued versus running items? <a href="#queued-vs-running" id="queued-vs-running"></a>

Each item in **Run Queue** shows its name, queued time, and current status.

**Queued** means the item is waiting for an available concurrency slot.

**Running** means the item has started and is already using one of your available slots.

Only **Queued** items show a **Cancel** control in the sheet. **Running** items do not.

## Why does Fetch Hive queue runs?

Fetch Hive queues runs so your account stays within its concurrency cap. When all available slots are already in use, additional work waits until a slot becomes available instead of starting immediately.

This is why you may see a mix of **Queued** and **Running** items at the same time. **Running** items are consuming slots now. **Queued** items are next in line.

## Concurrency usage

At the top of **Run Queue**, **Concurrency usage** shows how many slots are currently in use out of your total account limit.

The `{concurrency_count} / {concurrency_cap} slots` display helps you understand why an item is already **Running** or still **Queued**.

If there are no active queue items, Fetch Hive shows **No items in queue**.
