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.

Click on any of these topics to learn more:

• Uptime & Project Hours
• Container Space
• Request Rate

Uptime & Project Hours

To make Glitch accessible for everyone:

• Apps created on Glitch are given an allowance of Project Hours.
• Project Hours are spent when:
  • The project is being actively edited.
  • Someone accesses the user-facing side of a Glitch project that is not a static site
• Anonymous users get 120 free Project Hours.  However, projects that are created anonymously will automatically expire after 5 days.  To get additional hours and prevent your project from expiring, the anonymous user will need to register an account or transfer project ownership to an existing Glitch account
• Every registered user gets 1,000 free Project Hours each month. Project hours are replenished on the first day of each month at 00:00 UTC. Unused Project Hours cannot be rolled over.
• The Project Hours limit does not apply to Boosted Apps. If you are a Glitch Member the monthly allowance is 4,000 Project Hours.  Project hours are replenished on the first day of each month at 00:00 UTC.  These hours will be applied to any non-Boosted apps that you own.

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).
