Heroku Vibes runs in a controlled pilot to ensure stability. Keep these limits in mind as you build.

Message quotas

Account statusMessages per weekHow to increase
Unverified15Verify your account (free) to double the quota.
Verified30Contact Heroku Support if your team needs higher limits.
Messages include prompts and follow-up instructions. Deleting a project does not restore messages consumed for that week.

Project slots

  • 3 active projects per workspace.
  • Transfer or delete a project to free a slot.
  • Transferring spins up a Basic dyno in your account and does not consume project slots.

App generation limits

  • Daily caps protect shared infrastructure. If you hit a cap, wait until the next UTC day or contact Support with your use case.
  • Extremely long prompts may be truncated; break work into smaller iterations for best results.

Runtime characteristics

  • Temporary apps run on Eco dynos. They may sleep after periods of inactivity.
  • After transfer, the app runs on a Basic dyno ($7/month) by default. Adjust the plan to match your workload.

Support channels

  • Runtime or deployment issues: Heroku Support
  • Product feedback: heroku-ai-feedback@salesforce.com
Respecting these limits keeps the pilot reliable for everyone while we scale capacity.
