eCloud VPS Limits

The following limits apply to eCloud VPS plans per instance:

  • Processes: No limit on running processes beyond available RAM and CPU resources
  • Bandwidth: As stated in your plan (1 TB, 4 TB, or unmetered). Overage on metered plans incurs $0.02/GB
  • Snapshots: Up to 3 manual snapshots per VPS on Starter; 10 on Pro and Business
  • IPv4 Addresses: 1 address is available on all plans. Additional addresses $4/mo each
  • Reinstalls: No limit on OS reinstalls, subject to fair use
  • Support Tickets: Unlimited; priority queue on Business plan

ePanel Limits

ePanel is free and has the following limits on an eCloud service plan:

  • Managed Processes: Up to 50 PM2 processes per ePanel installation
  • File Manager: Upload limit of 500 MB per file via the browser interface
  • Log Retention: Live logs displayed in real-time; historical log retention depends on your server's disk space
  • API Requests: See API rate limits below
  • Installations: ePanel can be installed on any number of servers you own or manage

eAuth Limits

eAuth limits vary by plan:

  • Free: 500 authentication requests per calendar month. Exceeding this limit will result in auth requests being declined until the next month.
  • Developer: Unlimited authentication requests, subject to fair use
  • Enterprise: Unlimited, with dedicated infrastructure
  • Applications: Up to 10 registered applications on Free; 50 on Developer; and unlimited on Enterprise
  • Redirect URIs: Up to 100 on all plans, subject to fair use
  • Custom Domains: Not available on Free; 1 domain on Developer; unlimited on Enterprise

API Rate Limits

The ePanel and eAuth REST APIs are subject to the following rate limits to ensure platform stability:

  • ePanel API: 120 requests per minute per API token. Exceeding this returns HTTP 429.
  • eAuth Token Verification: 300 verifications per minute per client ID
  • eAuth Admin API: 60 requests per minute

Rate limit headers (X-RateLimit-Remaining, X-RateLimit-Reset) are included in all API responses so you can implement appropriate backoff logic.

Fair Use Policy

Services marked as "unmetered" or with high limits are subject to fair use. Fair use means usage consistent with the intent of your plan and not disproportionately impacting other customers sharing infrastructure.

Activities that constitute abuse of fair use include but are not limited to:

  • Sustained CPU utilisation above 90% for extended periods on shared infrastructure tiers
  • Network traffic patterns consistent with DDoS amplification or reflection
  • Automated abuse of the eAuth system (bot-driven fake auth requests)
  • Storing data volumes disproportionate to your plan's allocated disk space

If we identify fair use violations, we will contact you to discuss a resolution before taking any action. If you require higher limits, please contact us to discuss enterprise options.
