Possible disadvantages

  • Static Site Limitations

  • Resource Limitations
    Imposed restrictions on bandwidth and storage may not be suitable for high-traffic or large-scale websites.
  • Configuration Complexity
    Initial setup and configuration, especially when dealing with custom domains or SSL, can be complex for beginners.
  • Limited Customization Options
    While Jekyll is powerful, there are still limitations in terms of plugins and customization compared to more robust CMS solutions.
  • No Backend Support
    Inability to run backend processes or databases means that dynamic applications requiring real-time data and complex backend logic cannot be hosted.
  • Corporate Restrictions
    Enterprises or organizations with strict security or compliance policies may find GitHub Pages insufficient for their needs.
  • Dependent on GitHub
    Reliance on GitHub's platform means that any downtime or outages on GitHub can directly affect the availability of your website.

Questions & Answers

As answered by people managing Postio.co.uk and GitHub Pages.

What makes your product unique?

Postio.co.uk's answer

Postio charges only when a lookup returns a result — searching is free. Address, email and phone validation sit behind one API with a single JSON response envelope, so you integrate once rather than stitching three vendors together. Address data comes from Royal Mail's Postcode Address File under a direct licence, not scraped or resold sources. There are no tiers, contracts or minimum spend, and the first 100 lookups need no card.

Which are the primary technologies used for building your product?

Postio.co.uk's answer

A REST API served from edge locations, with official SDKs for JavaScript/Node, Python, Go, PHP, Ruby and .NET, all open source on GitHub. The API is documented by a public OpenAPI specification.

Why should a person choose your product over its competitors?

Postio.co.uk's answer

Pricing is published and pay-as-you-go: 2.2p per address, 1p per email, 1p per phone, billed only on a result. No sales call, no annual contract, no minimum commitment. You can be live in a few minutes with 100 free lookups and no card, and the same API covers all three validation types. For UK addresses specifically, the data is licensed directly from Royal Mail rather than obtained second-hand — which matters after the 2025 High Court ruling on database rights in this market.

How would you describe the primary audience of your product?

Postio.co.uk's answer

Developers and technical teams building UK-facing forms — ecommerce checkouts, signup flows, CRM and logistics systems. Typically small to mid-sized product teams, agencies building for UK clients, and software vendors embedding address lookup in their own product. It suits anyone who wants a UK-accurate API without an enterprise procurement process.

What's the story behind your product?

Postio.co.uk's answer

Postio is a trading name of Onno Group Limited, registered in England & Wales (company no. 08622799). It was built to make Royal Mail PAF-accurate UK validation available on straightforward pay-as-you-go pricing, rather than the contracts and minimum commitments that have been standard in this market. Address, email and phone validation were brought together behind one consistent API so a team can solve all three at once.

Who are some of the biggest customers of your product?

Postio.co.uk's answer

Serving a huge range of customers across the world looking for a blazing fast UK Address AIP product. From bootsrapped entrepreuners to FTSE 250 companies. We serve them all.
