  • 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

  • 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.

Questions & Answers

As answered by people managing EPOS-AI and Opalstack.

What makes your product unique?

EPOS-AI's answer

EPOS-AI reads and remembers your entire manuscript across sessions. Unlike generic AI writing tools, it understands narrative structure, tracks character consistency across chapters, and gives editorial feedback with full story context — not just on the current paragraph.

Why should a person choose your product over its competitors?

EPOS-AI's answer

Most AI writing tools lose context after every session and treat a novel the same as a blog post. EPOS-AI is built exclusively for fiction authors — it reads your entire manuscript, remembers your characters and worldbuilding across sessions, and offers three levels of editorial analysis that check consistency across chapters. It doesn't generate text for you — it makes your writing better. Swiss-hosted, GDPR-compliant, your manuscript never leaves Switzerland.

How would you describe the primary audience of your product?

EPOS-AI's answer

Fiction authors writing novels and series, self-publishing indie authors, traditionally published writers, freelance editors looking for AI-assisted manuscript analysis, copywriters and content writers who need deep text editing beyond grammar, and journalists working on long-form narrative pieces.

What's the story behind your product?

EPOS-AI's answer

Built by Marcel Tobien, a published author with 12 books across urban fantasy, children's fiction, cozy romance, and non-fiction. After years of frustration with AI tools designed for marketers, he built the writing studio he wished existed — solo, from scratch, in Weggis, Switzerland.

Which are the primary technologies used for building your product?

EPOS-AI's answer

Node.js, PostgreSQL, Claude by Anthropic (primary AI), Gemini and GPT as fallbacks, Stripe for payments, LanguageTool for spell-checking, hosted on Ubuntu with Nginx and PM2.

Who are some of the biggest customers of your product?

EPOS-AI's answer

  • Independent fiction authors in the DACH region (Germany, Austria, Switzerland)
  • Self-publishing authors working on novel-length manuscripts
  • Writers seeking professional-grade AI editing for their fiction
