Pricing | About Free Starter Plan | Deployment

  • Github integration for deployment
  • Has Postgres, Redis, MongoDB, MySQL
  • Can't run an app 24/7 at a free tier because it offers only 500 hours of usage per month

  • Apps are limited to 4000 requests per hour (subsequent requests will return a 429 "Too Many Requests" response).
  • 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. 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.
  • There's an additional 512MB of assets storage space. The maximum file size per upload is limited to 256MB.
