Cloudflare

Cloudflare Workers let you run backend code at the edge, close to your users, without managing servers. For APIs, that combination of near-zero cold starts, global distribution, and tightly integrated storage makes Workers a compelling platform in 2026. This guide explains how a Cloudflare Workers API is structured and...

Cloudflare sits between your visitors and your server, which makes it one of the most effective places to improve website performance. Used well, it serves content from a location near each visitor, caches what it can, optimises images, and compresses responses. Used carelessly, it does little or even gets in the way....

Images are almost always the heaviest thing on a web page, and the way you host them decides whether your site feels instant or sluggish. In 2026 the question is no longer “should I optimise my images” but “where should they live so optimisation happens automatically.” After years of resizing images on the edge for...

If Cloudflare Images is where your images live, Cloudflare Image Transformations is the engine that makes them fast. It resizes, compresses and converts your images to modern formats at the moment they are requested, using only the original you already have. No build step, no pre-generated thumbnails, no separate...

If you host a lot of images, the line item that quietly destroys your budget is not storage, it is egress: the fee cloud providers charge every time someone downloads a file. Amazon S3 and most competitors bill you per gigabyte served, so a single viral post or a busy product catalogue can produce a bandwidth invoice...

Object storage pricing is deceptively hard to compare because the headline storage rate is rarely the number that ends up on your bill. The figure that actually decides your cost is egress, the charge for serving data out to your users, and it is exactly the number that providers bury. Cloudflare R2 made itself easy to...

For most of the last decade, running an AI model meant renting a GPU server, managing drivers, and paying for that hardware whether requests came in or not. Cloudflare Workers AI changes the model entirely: you call an AI model the same way you call any other function in a Worker, it runs on GPUs distributed across...

For years the answer to “where do I deploy this on Cloudflare” was simple: static sites and frontends went on Pages, and serverless logic went on Workers. In 2026 that line has blurred, because Workers can now serve static assets directly, which means a single Worker can host your whole site, frontend and backend...

Nobody enjoys CAPTCHAs. Squinting at traffic lights and fire hydrants to prove you are human is a tax on every honest visitor, and the data those puzzles feed back to advertising networks is its own concern. Cloudflare Turnstile replaces all of that with a smart, mostly invisible check that confirms a visitor is human...

Serverless compute solved the “no servers to manage” problem for application code, but databases were the awkward holdout. You could run a Worker on the edge in milliseconds, then watch it wait on a database sitting in a single far-away region. Cloudflare D1 closes that gap: it is a real SQL database, built on SQLite,...
