No description of Opalstack yet.

Vizivo is an AI-powered document generator built for UK small businesses. Most AI tools start from zero every conversation. You re-explain your rates, your VAT position, your audience and your tone every single time. Vizivo doesn't. You profile your business once (or simply paste your website and...

Features and specs

What each product offers, as listed by its team.

Opalstack 5 features
Vizivo 6 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.
  • Business Memory
    Profile your business once, or paste your website and Vizivo reads it. Every document after that uses your rates, VAT position, services and tone of voice without you retyping them.
  • 14 UK business document tools
    Invoices, quotes, sales proposals, business plans, marketing plans, job descriptions, RFPs and responses, privacy policies, terms and conditions, budgets and website copy.
  • Built for UK conventions
    VAT-aware totals, British English, and UK legal and business norms by default, rather than US templates adapted after the fact.
  • Finished PDF and Word exports
    Documents export as formatted PDF or Word files with page numbers and consistent typography, not chat text you have to reformat. Paid plans remove the watermark and apply your brand colour.
  • Guided journeys
    Pick an outcome and Vizivo sequences the right documents in the right order. Launch a Business, Win More Clients and Get Compliant (UK), with everything a journey produces kept together in one project.
  • Quote to invoice in one click
    An accepted quote becomes the matching invoice with totals recalculated, so the figures cannot drift between the two documents.

Questions & Answers

As answered by people managing Opalstack and Vizivo.

What makes your product unique?

Vizivo's answer:

Business Memory. You profile your business once, or paste your website and Vizivo reads it, and from then on every document is written with your rates, VAT position, services and tone already in place. Most AI writing tools start from an empty context every session, so you re-explain your business each time. Vizivo also finishes the job: documents come out as formatted PDF or Word files, not as text in a chat window you still have to lay out.

Why should a person choose your product over its competitors?

Vizivo's answer:

If you need one-off text, general AI chat is cheaper and more flexible, and you should use that. Vizivo is for the documents a UK small business produces repeatedly: invoices, quotes, proposals, business plans, terms and conditions, privacy policies.

Three things differ. It remembers your business between documents. It applies UK conventions by default, including VAT-aware totals, British English and UK legal norms, rather than US templates you adapt afterwards. And documents connect, so an accepted quote becomes the matching invoice with the totals recalculated.

How would you describe the primary audience of your product?

Vizivo's answer:

UK small businesses: sole traders, freelancers, consultants and small agencies. Anyone who writes their own invoices, quotes, proposals and policies instead of having a finance team, a lawyer or a marketing department.

Newly formed limited companies especially, because incorporation is immediately followed by needing a business plan, terms and conditions, a privacy policy and a first invoice.

What's the story behind your product?

Vizivo's answer:

Vizivo started from a straightforward frustration: general AI tools are good at writing and bad at remembering. Every session began by re-explaining the same business details, and the output still needed reformatting before it could go to a client.

Vizivo was built around the opposite idea. Tell it about your business once, and it produces finished documents from then on. It is built and run in the UK by Vizivo Technologies Ltd, company number 17345034, designed for UK conventions rather than a US product with the currency switched.
