What technical restrictions are in place?

While we want to keep Glitch as open as possible, there are a few restrictions that apply to un-boosted apps. These restrictions are designed to maintain service levels for all, and to prevent someone’s accidental infinite loop from costing us a small fortune.


  • Apps sleep after 5 minutes if they are not used, and those running for more than 12 hours are stopped. They wake again upon receiving another HTTP request to the app's project-name.glitch.me address.
  • Registered users can have up 20 apps running simultaneously.
  • Anonymous users can have up to 3 apps running simultaneously.
  • Apps created by anonymous users expire after 5 days (login to keep your projects around).

Container Space

  • Apps have a limit of 200MB of disk space in the container. The contents of your apps's '/tmp' directory currently don't count towards that total, but those files are removed when the app restarts.
  • By default your Node.js modules don't count towards that total - there's a separate 1GB limit for node modules.
  • Plus, there's an additional 512MB of assets storage space.
  • Apps have a limit of 512MB of RAM.

Request Rate

  • Apps are limited to 4000 requests per hour (subsequent requests will return a 429 "Too Many Requests" response).

If your projects require more powers beyond these technical restrictions consider subscribing to Boosted Apps
