Slots control how many scrapers lobstr.io can run in parallel at the same time. Every plan includes a fixed number of slots, and you can see your current usage on the dashboard home page.

What is a slot?

A slot is a parallel scraper instance. Each Squid has a slots setting that determines how many scrapers it launches simultaneously to process its tasks — and each of those scrapers counts as one slot against your plan’s total. Open your Squids list and you’ll see the per-Squid slot count next to each entry:
List of Squids with their slot counts
Why do some Squids have more than one slot? Because the slots setting has been raised in their Settings to boost speed — each additional slot adds another scraper working through the task list in parallel.

To change a Squid’s slot count: open the Squid → Settings → adjust the slots value → Save & Exit. Higher slots = faster runs, at the cost of more of your plan’s total capacity being used at once.

​
How your total slot count is computed

Your total is the sum of the slots setting across all your active Squids. For example, with 5 active Squids:

Squid A1
Squid B4
Squid C1
Squid D1
Squid E4

​
Limits on the slots setting

There are two caps on how high you can set a Squid’s slots value:
  • 20 per run — regardless of your plan’s total, a single Squid can’t exceed 20 parallel instances in one run. Even on the Team plan (50 slots), each individual Squid is still capped at 20.
  • Number of synced accounts — for Squids that require account sync (Sales Nav, Leboncoin, Twitter/X, Facebook), the slots value is also capped by the number of accounts you have synced for that platform. One scraper instance uses one account’s session, so you can’t run 10 instances with only 5 linked accounts.
Plan slot allowances:
  • Starter — 2 slots
  • Pro — 10 slots
  • Team — 50 slots
To unlock higher slots on account-synced Squids, sync more accounts for that platform. Each additional synced account raises the ceiling.

​
Freeing up slots

If you’re approaching your plan’s total and need capacity for another Squid, deactivate any Squid you’re not currently using. Deactivating a Squid releases its slots immediately.

Open your Squids dashboard

Go to your Squids list.
2

Select the Squid to deactivate

Click the Squid you want to pause.
3

Set it to Inactive

Click Change Status to → Inactive. Your total slot count drops by that Squid’s slots value immediately.
Deactivating a Squid and watching the slot count drop
You can reactivate the Squid at any time — its slots are re-added to your total.
If you regularly need more concurrent capacity than your plan allows, upgrading is the most direct fix. Alternatively, stagger your Squid schedules so they don’t all fire at the same moment.

  • Account Sync — synced accounts are what let you raise slots on account-gated Squids
  • Account Bans & Limits — why slot capacity matters for account-based scraping
