Your next AI feature might not need a trip to the cloud.

In “Unlocking Client-Side AI in Your Web App,” Maximiliano Firtman shows how browser APIs and local models can bring text, vision and speech features straight to the user’s device. He covers options including WebNN, WebGPU and WebAssembly, and how to choose between built-in models, your own models or a cloud fallback.

@firt is a mobile and web developer, international speaker, trainer and author of 14 books. He’s created more than 35 development courses and teaches workshops on web performance, mobile development, PWAs and AI.

Your browser already has a performance toolkit. You might just not know where to look.

In “Web Performance APIs That You (Probably) Never Knew Existed,” Matheus Albuquerque explores the browser’s built-in tools for understanding responsiveness and tracking down bottlenecks. Expect a tour of observers, timing APIs, scheduling primitives, resource hints and View Transitions - and ideas for measuring what users actually experience.

Matheus is a Staff Front-End Engineer at Medallia, where he works on the surveys platform with React. He’s also a Google Developer Expert in Web Performance, a speaker on React and developer experience, and a volunteer front-end instructor at TechLabs.

You type npm install. A whole supply chain shows up. Everything’s fine… right?
In “What You’re Really Trusting When You Run npm install,” Karen Li unpacks the hidden network behind that everyday command: how packages get from publishers to your project, where trust can break down, and how approaches like identity-based publishing and provenance can help.

Karen is a software engineer at @GitHub whose path runs from concert pianist to elementary school teacher to technologist. She brings a teacher’s eye to complex systems - and lives by the motto, “I invest in brains.”

AI that runs in your browser, on your hardware, without calling the cloud? That’s not boring. That’s pretty handy.

In “Boring but Effective: WebAI That Ships,” Nico Martin shows how small open models can handle useful tasks right in the browser - from semantic search to speech recognition and background removal. No API key, no cloud subscription, no giant download. Just WebAI that’s ready to get to work.

@nicodotdev is a Machine Learning Engineer focused on WebML at Hugging Face, and a Google Developer Expert in AI and Web Technologies. He makes it easier for web developers to bring machine learning into the browser - and shares what he learns through workshops, articles and talks.
