Features and specs

What each product offers, as listed by its team.

Opalstack 5 features
Alt Audit 5 features
  • 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.
  • Alt Text Audit
    Scans WordPress sites to detect missing, empty, or low-quality image alt text.
  • AI Alt Text Generation
    Uses AI to generate meaningful, context-aware alt text optimized for accessibility and SEO.
  • Bulk Alt Text Generation
    Generate alt text for hundreds or thousands of images in one action.
  • Manual Review & Approval
    Review and edit AI-generated alt text before applying changes.
  • WordPress Media Library Integration
    Works directly inside the WordPress Media Library with no external tools.

Questions & Answers

As answered by people managing Opalstack and Alt Audit.

What's the story behind your product?

Alt Audit's answer:

Alt Audit was created to solve a common WordPress problem: missing or poor alt text across large websites.

Manually fixing alt text is time-consuming, error-prone, and often ignored until accessibility or SEO issues arise. Existing tools either lacked auditing or applied AI blindly without accessibility context.

Alt Audit was built to bridge that gap by combining: - Automated site-wide auditing - AI-assisted, context-aware alt text generation - Human review and bulk management inside WordPress

The goal is to make accessibility and image SEO practical and achievable, even for non-technical users.

What makes your product unique?

Alt Audit's answer:

Alt Audit combines alt text auditing, AI-powered generation, and bulk management in a single WordPress plugin.

Unlike basic alt text generators, Alt Audit first audits your entire site to identify missing, empty, or low-quality alt text. It then uses AI to generate context-aware alt text that aligns with accessibility best practices and SEO guidelines.

Key differentiators: - Built specifically for WordPress (not a generic SaaS) - Bulk scanning and bulk generation across media libraries and pages - Focus on WCAG accessibility compliance, not just SEO - Clear audit reports and full control before applying changes - Free monthly AI credits to test real workflows

Alt Audit is designed to solve alt text issues at scale, not just image by image.

Why should a person choose your product over its competitors?

Alt Audit's answer:

Alt Audit is ideal for users who want control, accuracy, and scalability instead of one-click automation with no oversight.

Compared to competitors, Alt Audit: - Audits existing alt text quality instead of blindly overwriting it - Allows users to review, edit, and approve AI-generated alt text - Works directly inside WordPress with no external dashboards - Supports bulk workflows for large sites and WooCommerce stores - Balances automation with accessibility best practices

Many alternative tools focus only on generation. Alt Audit focuses on fixing real accessibility and SEO problems responsibly.

How would you describe the primary audience of your product?

Alt Audit's answer:

Alt Audit is built for WordPress users who care about accessibility, SEO, and scalability.

Primary audiences include: - Website owners and bloggers managing large media libraries - SEO professionals optimizing image search visibility - Agencies maintaining accessibility standards across client sites - WooCommerce store owners with hundreds or thousands of product images - Developers and teams preparing sites for accessibility compliance

It is especially valuable for users who want to improve accessibility without manually editing alt text image by image.

Which are the primary technologies used for building your product?

Alt Audit's answer:

Alt Audit is built using modern WordPress and AI technologies.

Primary technologies include: - WordPress plugin architecture (PHP, hooks, REST API) - JavaScript for dashboard UI and bulk actions - AI models for image and context-based alt text generation - Secure API communication for AI processing - WordPress Media Library and database integration

The plugin is designed to be lightweight, secure, and compatible with standard WordPress hosting environments.

Who are some of the biggest customers of your product?

Alt Audit's answer:

  • WordPress agencies managing multiple client sites
  • WooCommerce store owners with large product catalogs
  • Content publishers and bloggers with image-heavy websites
  • SEO consultants and accessibility specialists
  • Small to mid-sized businesses improving compliance and SEO
