Plan limits
Each plan caps how much of certain resources you can use. When you hit a cap, the platform shows a modal explaining the limit and offers an Upgrade plan button.
The limits
| Resource | Community | Education | Pro | Teams | Enterprise |
|---|---|---|---|---|---|
| Orchestrators | 1 | 1 | 20 | 5 / seat | Unlimited |
| vPLC devices (across all orchestrators) | 2 | 10 / seat | 100 | 20 / seat | Unlimited |
| Private projects | 0 | ✓ | ✓ | ✓ | ✓ |
| Members per org | 1 (only you) | per Education agreement | n/a (personal) | per seats purchased | per contract |
| ACUs (AI Engineer) / month | 0 | 1,125 | 6,125 | 12,375 / seat | Custom |
"Unlimited" means there's no hard cap; usage is governed by your contract.
How limits apply per workspace
Limits are scoped to each workspace:
- Your personal workspace has its own limits, governed by your personal plan.
- Each organization workspace has its own limits, governed by that organization's plan.
So a Pro user (personal) who belongs to a Teams organization has Pro limits in their personal workspace and Teams limits in the org workspace. The two pools are independent.
What happens when you hit a limit
The platform blocks the creation that would exceed the limit, and shows a modal:
You've reached your plan limit. {Resource} limit reached ({used} / {total}) on plan {Plan}. Upgrade to add more.
Buttons: Cancel (dismisses) and Upgrade plan (jumps to the pricing page).
Examples:
- Trying to create a 2nd orchestrator on Community → orchestrator limit modal.
- Trying to create a 3rd vPLC on Community → device limit modal.
- Trying to make a project private on Community → private-projects limit message during the New Project wizard.
Grandfathering
If your plan decreases (downgrade, trial ends, subscription cancellation), the platform doesn't delete your over-quota items. Instead it:
- Lets them keep working.
- Blocks you from creating new items over the limit until you're back under.
Example: you were on Pro with 5 private projects. You downgrade to Community (0 private projects). The 5 stay private and you can keep using them. You just can't create a 6th private project until you upgrade again.
You can confirm your current state in Settings → Usage.
When the limit count looks wrong
If the usage page shows a number that doesn't match what you see:
- Click the small refresh icon at the top right of the Usage card to force a recount.
- Verify you're looking at the right workspace: limits are workspace-scoped.
- Recently deleted items may take a few seconds to drop from the count.
If it still looks wrong, contact support via the Feedback action in the user menu.
Where to next
- Upgrade to lift a limit → Upgrading and downgrading.
- Current quotas → Settings → Usage.
- AI credit semantics → AI Credit Units.
