We don't limit how many streams you can run simultaneously - only how quickly you can start new ones, giving you unlimited scale while ensuring reliable performance.
Free users can start 5 new streams per minute, while pay-as-you-go accounts start with 100 new streams per minute. Anytime you are using 70% or more of your current limit, your new sessions rate limit will automatically increase and scale up by 10% every 60 seconds. This means within 5 minutes of sustained usage, you can scale from 100 to 146 new streams per minute (for a total of 610 concurrent streams), with unlimited ceiling as your usage grows.
These limits are designed to never interfere with legitimate applications - normal scaling patterns automatically get more capacity before hitting any walls, while protecting against runaway scripts or abuse. Your baseline limit is guaranteed and never decreases, so you can scale smoothly from dozens to thousands of simultaneous streams without artificial barriers or surprise fees.
