Possible disadvantages

• Smaller Community and Ecosystem
  Compared to major hosting providers like DigitalOcean, AWS, or even shared hosts like SiteGround, Opalstack has a smaller user base, which means fewer community tutorials, third-party guides, and forum discussions available for troubleshooting.
• Limited Scalability Options
  Opalstack is primarily a shared hosting provider, which means it may not be the best choice for high-traffic applications or projects that require rapid, on-demand scaling of resources like CPU, RAM, or storage.
• Not Ideal for Beginners
  While developer-friendly, Opalstack's approach can be intimidating for non-technical users. Setting up applications often requires familiarity with the command line and server configuration, which may not suit those looking for simple one-click solutions.
• Limited Data Center Locations
  Opalstack offers a relatively small number of data center locations compared to major cloud providers, which may result in higher latency for users targeting audiences in regions not well-served by the available server locations.
• Fewer Managed Services and Add-ons
  Unlike larger hosting platforms, Opalstack lacks a wide range of managed add-on services such as built-in CDN integration, managed backups with granular restore options, or one-click SSL management that more mainstream providers offer out of the box.
