What each product offers, as listed by its team.

GraphComment 7 features

  • Near-Native Performance
    Lazy-loaded widget keeps Core Web Vitals close to a page with no comments at all.
  • One-File Migration
    Import your existing comments from Disqus or wpDiscuz in a single file.
  • Engagement Tools
    Nested Bubble Flow threads, votes, real-time updates, guest & social login, dark mode, 21 languages.
  • 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.

Questions & Answers

Who are some of the biggest customers of your product?

GraphComment's answer

What makes your product unique?

GraphComment's answer

GraphComment is the only WordPress comment system that blocks spam structurally: it closes the native comment endpoint so bots are stopped at the source, not just filtered — no CAPTCHA for your readers. AI-assisted moderation is included on every plan, even the free one. And unlike hosted platforms, every comment syncs back into your own WordPress database, so you never lose your data. No ads, no tracking, EU-hosted and GDPR-compliant.

Why should a person choose your product over its competitors?

GraphComment's answer

Compared to Disqus, GraphComment shows no ads and never monetizes your readers' data. Compared to wpDiscuz, features like AI moderation, customization, themes and dark mode are included rather than sold as paid add-ons. You get structural anti-spam, AI-assisted moderation on every plan, near-native Core Web Vitals, and full ownership of your comments in your WordPress database. The free plan includes every feature; paid plans start at $29/mo.

How would you describe the primary audience of your product?

GraphComment's answer

Publishers and website owners who want an engaged, well-moderated comment section without spam, ads or tracking — from independent blogs and mid-sized WordPress sites to news media handling large comment volumes. It fits anyone who takes reader discussion seriously and wants to keep control of their data.

What's the story behind your product?

GraphComment's answer

GraphComment was built to solve comment moderation and spam at scale for online media. The same infrastructure that powers comment sections handling millions of comments a month for national media is now available to every WordPress site — with structural anti-spam and AI-assisted moderation included.

Which are the primary technologies used for building your product?

GraphComment's answer

GraphComment is a cloud (SaaS) platform: a lightweight JavaScript widget that embeds on any website, plus an official WordPress plugin (PHP). The backend runs on Node.js with a real-time layer for live updates, and AI moderation combines large language models with a contextual analysis layer. Hosted in the EU.
