Overview Every session has resource limits to ensure fair usage and prevent abuse. Understanding these limits helps you build efficient applications and avoid errors.
Memory Limits Plan Memory Per Session Free 1 GB Paid 4 GB Enterprise Custom
When exceeded:
{ "error" : { "code" : "memory_limit_exceeded" , "message" : "Session exceeded 1GB memory limit" } }
CPU Limits Plan vCPU Per Session Free 0.25 cores Paid 1 core Enterprise Custom
CPU is shared and may be throttled under sustained high usage.
Execution Timeouts Plan Default Maximum Free 30s 30s Paid 30s 300s (5min) Enterprise Custom Custom
Configure per execution:

Disk Space Plan Storage Per Session Free 1 GB Paid 5 GB Enterprise Custom

Request Rate Limits Plan Requests/Minute Free 100 Paid 1,000 Enterprise Custom

File Limits Resource Free Paid Enterprise Max file size 10 MB 50 MB Custom Files per request 100 1,000 Custom Total files Unlimited Unlimited Unlimited
Best Practices
Monitor usage Check execution metrics to optimize resource usage
Set timeouts Use appropriate timeouts for different operations
Clean up files Delete unused files to stay within disk limits
Optimize code Efficient code uses fewer resources
