Features and specs

What each product offers, as listed by its team.

GPU Mart 7 features
Opalstack 5 features
  • Up to 80% Lower Cost — No Hidden Markup
    We own our hardware and skip the cloud middleman entirely — so you pay for raw GPU compute, not a platform premium.
  • Built for Long-Running Workloads That Never Stop
    Every plan, including GPU VPS, is a dedicated physical GPU — no virtualization. Performance is exactly what the spec sheet says, every hour.
  • Real Engineers — Responding in Minutes
    Our GPU infrastructure team is online 24/7. From provisioning to CUDA configuration, help arrives fast — every time.
  • AI Inference & LLM Serving
    The most cost-efficient GPU for AI inference — deploy LLaMA, DeepSeek, Gemma and other open-source LLMs with predictable throughput.
  • Generative AI & Image Pipelines
    Run SDXL, Flux, ComfyUI, and video models with full VRAM access and flat monthly pricing for cost-efficient large-scale generation.
  • 3D Rendering & Visual Production
    Render with Blender, Redshift, or V-Ray on dedicated GPUs — without render farm pricing or shared queues. Simple hourly or monthly pricing, no per-job markup.
  • Game Dev · Streaming
    Full Windows GPU environments with RDP access — rare among providers. Ideal for interactive workloads. Linux also supported.
  • Developer-Friendly Hosting
    Opalstack is designed with developers in mind, offering SSH access, Git integration, and support for multiple programming languages and frameworks including Python, Node.js, Ruby, and PHP, giving developers granular control over their hosting environment.
  • Affordable Pricing
    Opalstack offers competitive pricing for shared and managed hosting plans, making it an accessible option for small businesses, freelancers, and individual developers who need robust features without enterprise-level costs.
  • Modern Control Panel
    Opalstack provides a clean, modern, and intuitive web-based dashboard for managing sites, applications, databases, and email accounts, which is a significant improvement over older-style hosting control panels like cPanel.
  • Strong Support for Multiple Applications
    The platform supports a wide variety of application types including WordPress, Django, Flask, Express, static sites, and more, allowing users to host diverse projects on a single account with easy deployment.
  • Reliable Infrastructure and Support
    Opalstack is built by former WebFaction team members, bringing experienced hosting expertise. They offer responsive customer support and a reputation for stable, well-managed server infrastructure with good uptime.

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.
