How do I increase my Novita Sandbox concurrency limit?

Add account balance or enable a credit line to move from the Free tier (5 concurrent sandboxes) to the Paid tier (100). If you need more than 100, contact the Novita team for an Enterprise quota, which starts at 500 concurrent sandboxes and can be adjusted.

Details

Tier	Concurrent sandboxes	How to get it
Free	5	Default for new accounts
Paid	100	Add account balance or enable a credit line
Enterprise	500 by default, adjustable	Contact sales

usage.concurrent_instances (Python) / usage.concurrentInstances (JavaScript) from the quota API shows how many sandboxes currently count toward the limit.
Total vCPU and RAM in use across running sandboxes are also limited (concurrentVcpu, concurrentRamMb).
A request over your quota fails. Creation can also fail if a region has no free capacity, even when your quota isn’t used up.

How to

Check your limits and current usage before launching a large batch:

from novita_sandbox.core import Sandbox

quota = Sandbox.get_quota()
print("Limit:", quota.limit)   # concurrent_instances, concurrent_vcpu, concurrent_ram_mb, ...
print("Usage:", quota.usage)

import { Sandbox } from 'novita-sandbox'

const quota = await Sandbox.getQuota()
console.log('Limit:', quota.limit) // concurrentInstances, concurrentVcpu, concurrentRamMb, ...
console.log('Usage:', quota.usage)
