SliderDevs is a web development studio in Catania, at the foot of Mount Etna. We have been building websites and web applications since 2017 — first as freelancers, then as a team of three, and since 2021 as a studio of eight: four frontend developers, two backend engineers, one DevOps specialist, and one project manager.
We work on modern stacks — React, Next.js, Vue, Node.js, TypeScript, PostgreSQL. We deploy to Vercel, AWS, and DigitalOcean. We write tests. We document our code. We set up CI/CD pipelines. And we measure everything against the only metric that matters: does the website accomplish its business objective?
Catania might seem like an unusual home for a development studio. But Sicily has been a crossroads of technology and innovation for millennia — the Greeks, the Arabs, and the Normans all built engineering marvels here. Today, Catania is one of Italy's fastest-growing tech hubs, home to STMicroelectronics and a booming startup scene. We are part of that.
140+ sites shipped. Average Lighthouse score: 97. Average load time: 2.1 seconds. €8.4 million in tracked client revenue generated through the products we have built. We are not an agency that subcontracts to cheaper developers. Every line of code is written by our team, in our workshop, under our quality standards.

We deliver working software on schedule. Then we improve it based on real user data. Perfection is the enemy of deployment, but sloppiness is the enemy of trust. We find the middle.
Page speed is not optional. It affects SEO, conversion, and user experience. Every project ships with 90+ Lighthouse scores because we test before we deploy, not after.
Clean, documented, tested code. Because the developer who maintains your site in 2 years (whether that is us or someone else) needs to understand what was built and why.
