Limits

​

Concurrency limits

Pricing tier	Limit
Free	5 concurrent runs
Hobby	25 concurrent runs
Pro	100+ concurrent runs

If you need more than 100 concurrent runs on the Pro tier, you can request more by contacting us via email or Discord.

​

Rate limits

Generally speaking each SDK call is an API call.

Limit	Details
API	1,500 requests per minute

The most common cause of hitting the API rate limit is if you’re calling trigger() on a task in a loop, instead of doing this use batchTrigger() which will trigger multiple tasks in a single API call. You can have up to 100 tasks in a single batch trigger call.

​

Queued tasks

The number of queued tasks by environment.

Limit	Details
Dev	At most 500
Staging	At most 10 million
Prod	At most 10 million

​

Schedules

Pricing tier	Limit
Free	5 per project
Hobby	100 per project
Pro	1,000+ per project

When attaching schedules to tasks we strongly recommend you add them in our dashboard if they’re “static”. That way you can control them easily per environment.

If you add them dynamically using code make sure you add a deduplicationKey so you don’t add the same schedule to a task multiple times. If you don’t your task will get triggered multiple times, it will cost you more, and you will hit the limit.

If you’re creating schedules for your user you will definitely need to request more schedules from us.

​

Task payloads and outputs

Limit	Details
Single trigger payload	Must not exceed 3MB
Batch trigger payload	The total of all payloads must not exceed 5MB
Task outputs	Must not exceed 10MB

Payloads and outputs that exceed 512KB will be offloaded to object storage and a presigned URL will be provided to download the data when calling runs.retrieve. You don’t need to do anything to handle this in your tasks however, as we will transparently upload/download these during operation.

​

Batch size

A single batch can have a maximum of 500 items.

​

Log retention

Pricing tier	Limit
Free	1 day
Hobby	7 days
Pro	30 days

​

Log size

We limit the size of logs to prevent oversized data potentially causing issues.

​

Alerts

An alert destination is a single email address, Slack channel, or webhook URL that you want to send alerts to. If you’re on the Pro and need more than 100 alert destinations, you can request more by contacting us via email or Discord.

Pricing tier	Limit
Free	1 alert destination
Hobby	3 alert destinations
Pro	100+ alert destinations

​

Machines

The default machine is small-1x which has 0.5 vCPU and 0.5 GB of RAM. You can optionally configure a higher spec machine which will increase the cost of running the task but can also improve the performance of the task if it is CPU or memory bound.

See the machine configurations for more details.
