Green Custard

Super-fast B2B Jamstack Website With Gatsby js and Headless Sanity.

About The Client

Green Custard is a cloud-native professional services company and AWS Advanced Tier Services Partner, helping clients innovate and deliver value back to the end-users and customers.

Green Custard works across multiple sectors and with a broad range of client sizes, from entrepreneurs and tech start-ups to global enterprises and public sector organisations.

They are focused on the four key disciplines: IOT, Cloud infrastructure, Apps and Cloud Operations.


When Green Custard reached us, their existing website was already built with Jamstack. The User Experience wasn’t bad, but because of the chosen tech stack, they struggle with scalability, new page creation and content management.

They wanted to get a new, one-of-a-kind website that would reflect their knowledge of the latest technologies and wide experience in that field.

We started the project with the discovery phase, where we determined all the essential components based on the customer requirements and site map.

We delivered a document covering the components and available options for each and every page, so the customer could get acquainted with the scope of work and confirm that all the requirements would be met.

The customer didn’t establish the design, so our UI designer proposed two different style scapes accordingly to the brand visual concept.

The chosen style scape was the foundation for the components library and wireframes that we created to present the UI and UX design.

The team of four was delegated for the project delivery. It consisted of the JavaScript Developer, UI developer, Project Manager and a Tester. To run the development phase smoothly, we run the daily meetings to check the work progress and quickly deal with any blockers that could impact the delivery of the sprint.

Apart from our internal meetings we met the customer every other week for status meetings to keep him up to date with the progress.

Technologies chosen for the project





Why Gatsby.js?

While choosing the tech stack, we were also considering Next.js. We found Gatsby.js more appropriate for this project because most of the Green Custard website (besides the Contact form) can be statically generated and it’s not updated very frequently.

Our general approach at Pagepro is to choose Gatsby for smaller, less frequently updated marketing websites. Gatsby allows building highly performant websites that are easy to maintain. It also allows us to use a leverage of rich plugins ecosystem.

Even though Next and Gatsby are quite similar, they differ in the use cases they are best suited for. We’ve created an article on which one to choose and when. If you’re not feeling like reading, check out the video:

Why Sanity?

Sanity was the best choice for this project because it provides full flexibility in content management. It was Green Custard’s primary requirement because employees from different departments were about to collaborate during content distribution.

Live previews were another important factor for the customer. Green Custard didn’t have this option in the previous CMS, so content management was time-consuming and ineffective. Live previews in Sanity enable you to keep an eye on the overall look of the content during creation. Just take a look:


We decided to go headless because this is the best solution for flexible content management in future-proof projects like this one. The headless approach decouples content management from the presentation layer, which brings many benefits, like:

  • Flexibility

  • High Security

  • Reusability

  • Easy Content Management


We split the development process into 4 phases:

  • Initial Works

  • Static Version Development

  • Headless CMS Integration

  • Finalization

We chose Pagepro because they passed our technical test, and their offer matched how we wanted the website to be done. In addition, we liked the flexibility of their package. Pagepro’s team was accommodating, and they did small tasks outside of our contract.
