Startups are prototypes

Startups are prototypes

A startup isn’t just an early-stage company. It’s a mechanism to reduce uncertainty. Every early customer, product release and funding round exists to answer one question: have we learned enough to justify the next investment? A startup is essentially a super complex prototype designed to validate...

Shapeshifting the Future

Every year we open our doors for a week to a student trying to find their way into the industry. Not work experience in the shadowing-only sense but a real placement, with a real brief. We do the same for a roomful of UCL students, in the studio for an afternoon. From the outside, a career in this...

Your biggest asset in an RFP, your website

Your biggest asset in an RFP, your website. I’ve spent most of my career in B2B, and at Made by ON I spend my weeks talking to leaders of the world’s most exciting B2B businesses. Lately those conversations keep circling one question, which I put to our strategists and UX team: what happens when...

From static frames to a creative operating system

From static frames to a creative operating system

Looking beyond the flashy generative UI, shader effects and animation features at Figma Config signaled a deeper, more structural shift: the transition from a static repository of files and rules into a behavioural operating system. I left San Francisco with a camera roll of screenshots and pages...

Standardise the foundations, not the brand experience

Detailed work at scale comes down to one judgement: which parts of a project are worth building fresh for every brand, and which should be solved once and reused everywhere. Shared functionality on one side, brand expression on the other Engineering teams have plenty of frameworks and platforms to...

Putting video back where it belongs

The problem with putting video in a git repo. The repo kept getting heavier, sprint after sprint. We were committing big MP4s next to the code, builds were slowing down, and deploys with them. Case studies lead with video, so every new client made it worse. We needed the media to live somewhere...

WordPress can now describe itself to machines. WordPress 7.0 landed back in May with AI infrastructure in core. There’s an AI Client, a Connectors screen where the provider keys live, and the Abilities API, which actually arrived back in 6.9. Abilities are how core, plugins and themes describe what...

Cache Components: the right content at the right time

Cast your mind back to the earlier days of the world wide web. A website was essentially a digital document, the web a library, and the internet the mechanism of delivery. Updating a document meant editing HTML on your computer and uploading it to a server by hand, usually over FTP. In 1995 PHP...

We build by leaving things out

Most of what makes a WordPress site good is what we choose to leave out of it. WordPress runs a large part of the web on a big promise: whatever you need, there’s a plugin for it. That promise is one of its greatest appeals, and its most costly trap. Almost everything that harms a WordPress site...

Letting type move

Letting type move

We treat type as something that sits still — fixed in place, headings always the biggest thing, motion bolted on at the end. For one Creative Spark we dropped those rules and asked what type could do once it started moving. Creative Spark is our in-house R&D session: ninety minutes, a single theme,...

Cache Components: the right content at the right time

Cache Components: the right content at the right time

Cast your mind back to the earlier days of the world wide web.

A website was essentially a digital document, the web a library, and the internet the mechanism of delivery. Updating a document meant editing HTML on your computer and uploading it to a server by hand, usually over FTP. In 1995 PHP arrived and changed that, generating the HTML on the server from content held in a database. Paired with MySQL it became the standard way to build a site, and still underpins WordPress, a popular CMS.

As the web grew into more than a delivery system for documents, the technologies evolved with it. React and Next.js let us build static sites in JavaScript and lift them with rich interaction and animation. But fresh content and the performance of a static build pulled in opposite directions.

Pulling content from a CMS like Storyblok, Next.js does much the same job as PHP, combining it with HTML and CSS and delivering a page to the browser. Run dynamically, this happens on every request, so a CMS edit is live the moment it’s made. The cost is latency, heavy API usage and a larger bill for the client. Run statically, the work happens in the background on a regeneration schedule. Performance improves, costs and latency fall, but content lags behind.

The fast-versus-fresh trade-off A two-by-two matrix. Performance runs fast (top) to slow (bottom); freshness runs stale (left) to fresh (right). Static sits top-left (fast but stale), Dynamic bottom-right (fresh but slow). The fast-and-fresh corner, top-right, holds a unicorn — the mythical ideal. The slow-and-stale corner, bottom-left, holds a skull.
Every approach traded one for the other. Fast and fresh at once was the unicorn — the corner nothing could reach.

It’s now 2026, and Next.js 16 has cracked it. What if we could have the best of both, heavy caching for performance with content updates that still land instantly? Better still, what if different parts of a page could refresh at different speeds, depending on what they are for?

Cache Components is the new Next.js caching model that does exactly this. Caching becomes something a developer declares in a single line, around one piece of data or an entire component. Every part of a site carries its own strategy, regenerating from fresh content precisely when it needs to.

Every part of GFSmith’s page carries its own cache tag: commerce revalidates on price and stock (Saleor), editorial on publish (Storyblok). Learn more about our work with GFSmith.

As part of our relationship with GFSmith, we’ve been tasked with building out their e-commerce presence to reflect the exciting new brand. The intersection of editorial content and e-commerce is the perfect use case for these behaviours. Data updates to the catalog within the Saleor platform trigger a flush of the cache of the relevant pages of the site: consequently, a pricing update will show almost instantly. The editorial elements of these pages are left untouched, updating independently.

Anything we do leave uncached doesn’t hold up the page. Next.js sends the cached shell straight away, with a placeholder where the live part will sit, then streams it in behind. The visitor gets the page immediately, and the live data is accurate to the second. The approach is called partial prerendering. The framework gives us the mechanism; the judgement is in what we choose to cache.

Partial prerendering: a cached shell sent instantly while dynamic parts stream in On the left, a browser sends a cached shell immediately, with dashed placeholders where dynamic content will load. On the right, dynamic content cards stream in, shown by arrows pointing into the placeholders.
Partial prerendering: the cached shell arrives immediately with placeholders where the live data will sit, then the dynamic parts stream in behind them.

The cached areas still need to update when someone edits them, so we add a webhook to the CMS. Cached content carries tags, and an edit in a CMS like Storyblok expires only the tags it affects. The change surfaces almost at once, and nothing untouched is rebuilt.

Granular caching of this kind isn’t unique to Next.js, and other platforms arrive there by their own routes. What has changed is the arithmetic. When we reach for React and Next.js it is for the fluidity they give users, through considered animation, richer state and frictionless movement between pages. This used to result in trade-offs over efficiency & performance. Now we’re able to more confidently deliver these features as part of highly performant and efficient builds which always deliver content fresh.

One of the 214 hand-drawn sheets of Inō’s map of Japan, and his team surveying Mitarai in 1806

Measure

In 1800 a retired sake brewer named Inō Tadataka set out to walk Japan’s coast. He spent 17 years and 35,000 km on foot, and died before the work was done. His team finished the first accurate map of Japan in 1821, and it stayed in use for a century.
